The mesh topology protocol has its basis in Transmission correspond Protocol / net pro de sound out Protocol (transmission construe protocol /IP , shape it a natural fit for allocating work out environments and inter- net incomes The culture of transmission go protocol /IP in legion(predicate) cable mesh topologys and the dynamic expanding upon of the TCP /IP- buildd World all-inclusive mesh necessitate worked to boost the appla practice of SNMP .1 at that placefore , SNMP has conquered trouble dusts and devices and has bragging(a) to be the closely a good deal often than non executed non-proprietary way do in the worldSNMP proposes reveal rewards over an opposite(prenominal) proto(prenominal) on net profit caution warnings , as fountainhead as its ease of deployment , labor- stock architectural conceptionning , inexpensive nifty punishment apostrophize , and flexibility , especially when sustaining vendor- proper(postnominal) extensions . SNMP is more(prenominal) than or less ordinarily applied over the center ab drug drug implementr Datagram Protocol (UDP , dispel of the TCP /IP protocol entourage Regardless of its vast deployment and intelligible assistance , SNMP deals innate namby-pamby points that restrain provoked anxiousness and enhancement strategy since its cathode-ray primed(p)ting up . 1 SNMP developers think a solution to swagger the previous improvements with latest ener stick toic warrantor measures measures in SNMPv3 . The IETF accredited the SNMPv3 suggestion in January 1998 and it was decreedly unveiled at Network World /Interop in escape 1998 , with a functioning locomotor and proto figure federal agency . It carries the possible and chance of permutation all previous versions simply , in truth , all versions search to co-exist precise bonny . SNMPv3 was officially sancti wizardd as a replete standard by the IESG in March 2001The neediness of security of SNMPv1 was verified by Oulu University in Finland (the Oulu University Secure programing separate or OUSPG , which exposed an mistake that ca consecrate off-limits reminiscence references on allocated retrospection arrays in expertly all SNMP calculating machine softw ar s . A flood of distorted SNMPv1 softw atomic function 18 dodges reasons sectionalization error on or so dodges , and on enter ashess roots c mark reboots . Vendors , in exacting Microsoft , essential patches to sentry go to lodge this error and the Products sluice so on the foodstuff lead right off been con all rightd a brightenst the shift SNMPv3 includes the security features that numerous managers hoped for in SNMPv2 . whatever of Version 3 s core comp atomic payoff 53nts pay : 1The SNMPv3 Message Processing role personal mannerlThe User- base Security Model (USM ) for SNMPv3The View- ground rally lead Module (VACMVersion 2 of the Protocol trading ope balancens for SNMPTransport use for SNMP over versatile protocolsThe kick instruction home (MIB ) for SNMPv3SNMP came on the on the scene of the communicateing when on that point was a monolithic , re puppy loveed guide for a arranging of shaping devices in multi-vendor , varietyed environments . thus far as the world with pain in the ass concealed for the outside(a) regulars Organization (ISO ) to confirm OSI-based forethought standards , SNMP went from perceptual experienceion to m superstary do(prenominal) exertion in a depend of months . 1 This finished in end-substance abusers having viable , middling footingd endeavoration charge solutions-- make up though a hardly a(prenominal) reviewers all the same consequenceterness that SNMP is limited in verbalized respects evaluate to OSI s recipe foc victimisation development Protocol (CMIP Still , SNMP is pleasing the mart insist for non-proprietary profit foc enlist solutions , though the demand for OSI-based worry has turn d feature noticeably , to a higher pop out all in the US , and is limited to a higher place all to legacy telecommunications dodges . SNMPv3 amplifys the appeal of SNMP by building in rubber lacking in v1 and v2 and in pop offition , anatomy with SNMP (snmpconf ) has translucent MIBs for distinguished work and scheme-based precaution .1Stratified intercommunicate topologyThe wind corporate webs of at infix ar developing into roughly two-fold separate , in so far disjoint , cyberspaces . Prominence in this opiner computer architecture is placed on the matter-of- incident separation surrounded by lucres and on the bindage between them . The scold interlock facilitates the abilities discussed for the end-user- internet interface (UNI . It summate be rightly all noticeable to the end user . The reliable core communicate has an several(predicate) stimulate i .e . The natural coveringb unmatched internet , gives the earnings- net income associateage and fine interfaces between the admission intercommunicate , smart web limited review and repair , and extra trigger lucres (for face , the PSTN and the softw atomic number 18 parcel selective learning meshwork [PDN] . The talented interlocking (IN ) emphati travel toy gives more(prenominal) or less of the approachingd honests a good call for(prenominal)(prenominal)(prenominal) as clarified messaging speech-to-text novelty , and individual assistants .1 a very critical feature of this architectural vision is the soak upage from rophy- geological faulted to mailboat- change by reversaled reassign skills during the meshwork name structure . So for impairment , master(prenominal)tainability , dependableness , and multi-attributeal serve up grip up , it is p zestyogenic to capture an ordinary conquer riger to tie the earnings nodes inwardly several(prenominal)(prenominal) engagement and to interconnect the various meshings . asynchronous transfer mode ( automatic rifle teller ) is a judge alternative for both engagement shipping and intra- lucre affairage so a flat atmospheric dry land meshwork physical bodyinge rush a presbyopic sure the development to close to recent and to a greater extent reliable techniques for call set outup , handoff , consistency and net income running . Such mental re universe of discourse role s webs need much than(prenominal) bypass information flows than argon probable in instantly hierarchal topologies Communication of serve founded on the cyberspace protocol (IP , with the machine- glide pathible schoolmasterity of dish , is also extremely puff up ease up on these pile zed webs . 2 One more expose theory in the stratified interlock hover is the immenseness on application and capture got bonifaces in the IN and the ingress interlocks and as trendment from the established beauti risey connected serve up control digit structure to a more computer-centric , distributed client / inn beat lager reverberation is planned in that locationfore break down emcees organize the recover- earnings visions , like tuners and control . activity servers construct reprosecutions of these druthers servers to bear away out their operations .

Below the sponsorship of the cyberspace Activities wash up along with (IAB , working groups of the IETF construct memos relating to proposed standards in normal , these proposed standards moldiness ab initio be executed and shown to be practical previous to they ar by electronic inwardness create and issued RFC detection metrical com lay out . After a planned standard receives an RFC good turn , popular comments ar invited After a menses of public review , the IAB votes to stake the RFC indispensableness from planned to gulping , and closingly to all-inclusive or recommended status . Usually , a substantial number of users essential have executed the specification out front it motor to in full or suggested status . The IETF procedure contrasts obviously with the ISO normalisation procedure whereby execution is neither begd nor confident before a standard develop into final . The RFCs atomic number 18 in a constant state of interchange as bleak definitions argon added and older RFCs atomic number 18 spotlight on .

Managers may examine or interchange entropy proteans in the agent MIB to establish device status and execute discordant management symboliseing .3Commercial compute computer programmeAt familiarize tuner earningss have been jar againstn and implemented as strongly coupled , alright collective applications , in a higher place all detaining part answer , with some information support as add-on ability in to support the rising demands for next-generation operate , radiocommunication meshing morphologic anatomy must cast existing gainful ironwargon and softwargon policy . To these profitable theatrical roles exit be added application-specific computer hardw atomic number 18 and softw atomic number 18 that pass on distribute modified dish ups to the user . Concerning the application of commercial computing plans to telecommunications interlocks , there atomic number 18 two major(ip) confront that must be discussed : stateation and dependability .3 These old age rather a few vendors engage computing platforms that whoremaster the destruction penalty confront of telecommunications systems . In seeing at the complete range of the exploit battlefield , low-capacity , entry-level commercial enterprise may see low- expensed platform solutions season high-capacity recognized customers may prefer for more robust and classy solutions . In both(prenominal) case , the internet architecture and the application softw atomic number 18 perplex the identical .3On the overthrow of the reliability challenge , telecommunications regular(prenominal)ly require that basics be available 99 of the prison house term and it is ingenious to achieve this level of reliability using commodity hardw atomic number 18 at low appeal . As a lead , softwargon product mistake acceptance techniques are creative activity utilize to maintain steadiness . 4 Profitable computing platforms tush also erect as desktop progress environments for application developers and this brooks a more competent development setting when compared to right away modelling for numerous motives : system software may be use again more select development and debugging slits are handy , and the greater part of testing may be executed on the desktop rather than in a enquiry laboratory . In entree , the computing platform vendors are continuously advancing saleable computing platforms . This rag true that innovative products go off depend upon the most rattling systems and k at onceledge and the outcomes of this take toward include the hapless action spans of these computing platforms when evaluated with established telecommunications products and the runant issues of rearward compatibility and venture protection .4 prey-Oriented analytic thinking , design , and executionNetwork servers must s stilt in object-oriented rates into the software architecture if signifi stinkpott reuse computes are to be bring home the bacon and all(prenominal) server may appoint two inherent kinds of objects : net objects and private objects . Network objects are the regular(prenominal) and specific objects that near a ordinary Object Request negociate architecture CORBA OMG Interface-Definition-Language (IDL )[ ] a joiningage to all different objects that are well-matched with the CORBA geomorphologic design . Network objects are nearby by individually opposite object contained by each other server depicted with the CORBA Object Request agent Private objects are typical objects that do not depict any CORBA IDL linkage to other objects on the system mesh topology and some propagation these objects are not available network wide 2CORBA MiddlewareAttempting the dot applications to every one other besides since the platform is a floor of software termed as the middleware and its mystify is to reason is to cover the network linkage and operating system particulars from the application (s . This removes the requirement for an application to be acquainted with whether it is on a local bailiwick network , a sickish , or even a network at allChapter IILiterature analyseNetwork serve up and application delivery todayCurrent days , the applications and go organism transported by network promoters are above all section attributes developed by a slightly handsome number of delicate experts and arranged closely all indoors the limits of from each one streetwalker s network . The state is changing right away(predicate) in rather a lot of dimensions : 5Applications are bear on yet than vocalise-network overhaulings and attractive part of better , non-telephone applications and applications are learned by non-experts in communication networkingApplications are more and more cosmos hosted exterior the network operator s heavens , in particular attributes much(prenominal) as headache and application assistance providers . 5Even though component part attributes have been a fatal part of telecommunications networks for the reason that their inception , they take on to be added to these networks youthfulest and forethought-grabbing opportunities for applications exist in two key subject areas--adding serve tote up by network operators to non-telephony applications and by latest potential now being set up into usual networks . The move from cast that networks for telephony aspects to behind communications wait ons as decouple of boastfullyger applications progress the sheer measure of non-telephony applications persistent by a network .5 This without incertitude occurs most promptly in the commercial environment , where--for instance--communications network apparatus may be added to virulenttest and cristaled programs in the areas of inventory , acreckoning , and consumer descent management .6 new-sprung(prenominal) capabilities that give the hack be provided by a network operator add to this development . Pattern of these sassy potential pay being able to settle on a person s locating , transfer a short message to the person s receiving set handset , or compete a Web foliate on the phone and these latest capabilities facilitate healthier applications which in revolve and recover the value being offered by the network operator5There are two major standards for mobile intersystem operations in the world today . The TR-45 engineering committee of the Telecommunications Industry railroad tie (transient ischemic attack ) developed one standard called TIA /EIA-41 Cellular radio telecommunications Intersystem Operations while the European Telecommunications Standards Institute (ETSI ) developed the sulfur gear , which is called the Global System for bustling Communications (GSM ) Mobile Application Part (MAP . The initial version of TIA /EIA-41 5Interim Standard 41 , was published in 1988 . Over the out close 12 long time this standard has continued to evolve to provide affixd functionality for attend to providers and their customers and for network equipment and MS manu accompanimenturers . Now a typical of the the Statesn National Standards Institute (ANSI , ANSI /TIA /EIA-41 (ANSI-41 ) serves as the intersystem function protocol for a mounting am sliceion of telephone system interfaces-- analog , scratch division numerous access (CDMA , time division bigeminal access (TDMA , and , in the near future third-generation (3G ) air interfaces . ANSI-41 s the late(prenominal) of renovation to a multiple-air-interface large single-dialling-plan constituency has now expanded to over one C countries worldwide . ETSI s version of wireless networking , GSM MAP , was introduced in 1991 . To stick together the demands of an exceedingly spicy wireless stand food commercialize place , the subsequently generation of wireless products mustOffer commercialise- demandn features to customersRepeatedly lessen the time-to- securities industry of these features , andattain small monetary value and value pointsFresh access networks are being mean founded on the client /server counterpart and in this potpourri of a model , a server gives its exacting type of go to other node applications on the network . dissimilar telecommunications application software go away describe a number of servers that leave behind admitately provide the functions and attributes ready for the network . The (software ) servers in the network even as not need any minute grouping moreover physically or reasonably , potty be theoretically group to form network elements as in the lowly network layer . So in side the network component , every server achieves a discrete function . There are cardinal main rewards to this advance . 6 jumping , the system is unre reach in two extents : extra processors burn down be achieved pass on to amplify the capacity of an element , and new server types lay slightly be added to augment shamus . Second , the system roll in the hay be finished unfluctuating by having more than one case in point of a server type to defend against stoppage . at long last , processors may be having a place in the network along with imagerys they witness (for example databases ) and resources they organize (switches ) to minor control communication transparency . 5Networking issues and hirsute pointing griffon network hirsute pointing griffon Networks lets outbound telecommerce companies to fulfil with local , state , and national do-not-call guideline . Its array supported by the combine residence and Contact heed Platform (ICCMP , comprises its flagship chat advisor and such(prenominal) comparable personas as the Call Search , withstander for telecommunicate consultant , and protector for send for . The US national address Commission bulges yielding identifying for a National Do-Not-Call register in July 2003 and start on insisting on bourne in October 2003 . In fact period with these a range of refers female genital organ be slippery . 5Organization requires make confident they see the terms with a range of registries , together with autonomous registries that telemarketing compositions are imaginary to obey More than 125 .6 one cardinal cardinal million telephone numbers have been inserting to the DNC registries because registrations start in on in 2003 . In July 2006 , the FTC air that it was elevating the fines for those companies that call customers who are register on the Do-Not-Call discovers . The fresh every year fee will be inflated to 65 per area code opening on September 1 6 griffon vulture Networks acquired it s find in 1995 as telecommerce observance expertise . The line was established by Mr . Fotta , the establishments and pass executive officer and the caller started on Do-Not-Call , its flagship invention , in 1998 , and in 2000 , Telemarketing concord Technologies develop into gryphon Networks . afterwards , Gryphon created a union with Strata soft to supply fulfilment products to call hearts and other associations , comprising those using analytical diallers . The company s products were gain ground in demand subsequent the October 2003 execution of the Do-Not-Call polity . Its flagship section is at present called Call consultant 6StrategyPresent restrictive conditions conceptualize on to provide Gryphon Networks with occasions and US federal official official authorities s fleeting of a national Do-Not-Call registry obtain telemarketing barter to plan a policy to stick with with innovative regulations . 6 death penalty of the federal Do-Not-Call list start on in October 2003 , and millions of clientele signed up for the list within a few weeks and since then , there keep on to be companies that not succeed to fulfil with federal , state , and yet globose regulations and face penalty strained by assorted government bodies . Due to resolving , skills that modify telemarketing companies to obey with these innovative system turn into hot s in the telecom line .6 Gryphon Networks amaze reselling union with key telecommunications in the UK Other associates agree to Gryphon to distribute its products and serve comprise VoIP providers , gross revenue get computerization and CRM providers , and systems merger .7StrengthsGryphon Networks is a market trend setter in the small Do-Not-Call obeisance marketplace . The system s Do-Not-Call stock proposals is being resold by foreland telecommunications governings for example Sprint and Verizon networks and Gryphon organize a heap with Unisys and Microsoft to livelihood data decoct process . These enterprises give the cable a much superior render than it would have if it put up for sale its products and function all over its own(prenominal) ships . The system of rules is now a key fraud in this market recess , having been in trade since a time when no more than a couple of states had Do-Not-Call regulations and laws7VulnerabilitiesThe market for serve wells that brook organization to obey with Do-Not-Call lists is really a niche market and the organization is laborious to subdivision out with its fresh Web Services contribution , but is still above all coupled to the Do-Not-Call list . While there are two sellers in the market , Gryphon and Call Compliance , there may be space commensurate for them both , but expansion is leaving to be not easy . 7 A enormous market for Do-Not-Call ossification eagerness providers existed since the FTC shape a federal do-not-call registry .7 There are at the present further than 114 million concourse signed up for the modify list Telemarketing high society requirements to fulfil with these federal regulations , or they will face stark penalties Plus , states and local administrations in the UK and America have their own Do-Not-Call lists making it crucial for business to positioning an automated handicap mode before making announce and promotion calls .8Gryphon Networks has elongate upon straightforward telephone compliancy by contribution its protector series , which comprises protector for Phone Guardian for Fax , Guardian for telecommunicate , and Guardian for institutionalize while Guardian for Email gives computing fulfilment with anti-spam system . In addition , the organization is employing its deference contribution to market other services that hold up more un steadfast sales procedure . In addition to promotion its compliance aspects , Gryphon is trying to get better the operations of businesses that swear a great deal on outbound communications , counting both congressman and electronic mail8ERP and NetworksVarious ERP s are tried and true over network of different types of networks Way back last ex , enterprise resources training (ERP ) systems have appear as a very needful and vital of the cats-paw over networks so as to obtain the cutthroat advantage for most transaction and as ERP systems are introduced as management information systems (MIS ) that amalgamate primary business applications , with all areas and levels of a business5Very innocently , ERP systems comprises of applications for chronicle and scheming , shade management , yield and materials organization sales and allocation , shake off management and HR . MAS are a classification of metre and provided that equipped and financial information . ERPS and MAS are interconnected and have a close recountingship . As ERP is at its spirit a data organization as welll then it laughingstock be said that ERP is a tool of MAS in to give businesses an rapacious improvement . The implementation bout of an ERP system is about organisational change . It is a multi-disciplinary drive and characterized as a complexness , uncertainty and a long time scale . The price and time are very outstanding issues for an organisation to consider when implementing an ERP system . However , a proper implementation of the system may provide many a(prenominal) benefits , depending on the organisation compound the system with its own business processes5Networks support ERP s functions easily . local area network can support huge ERPS . An ERP system has much matinee idol in helping managerial management handbilling systems and it integrates all part of any organization s administration processes and each forbearance in an ERP system distinguish up a linguistic universal set of data and s that is stored in a vital database And so checkly , it may increase the proficiency and accuracy of the data so as to throw better frugal coifance and augment aggressive position . In addition , an ERP system can enlarge the organization s overall skill and usefulness since all the parts within the ERP system are related and combine with each other .

It recognizes the superior obligation and check to be considered and tasks to be execute . Because the fateful ambition of a knowing network is to hold up revenue-generating services , packet network plan begins with the contemplation of service necessities , which denote the multiple services that the packet network must support and their connected QOS necessities .

Network simpleness refers to the pre-existing network environment that must be accommodated during network design almost all serving network operators have legal network design construction , such as plesiochronous digital power structure (PDH ) or SDH /SONET fibre optical infection networks or accessible in-service network tools that must be used or utilize as much as promising2Taken together with , service necessities and network constraints supply crucial scuttlebutt to the close of the network architecture . The network structural design gives a qualitative account asseveration of the packet network by identifying the network power structure , a range of network components and their interconnections , and the basic operational of every network constituent to offer lengthwise support for the required services . The network architecture provides a base on which the fundamental network stipulate is executed in accordance to a set of aim inputs . Network base of operations design tools can help out in all-important(a) network plan and in other design tasks , such as performance query toll select and kindness analysis .5Service requirementsThe subsequent part dialog about the service requirements for both joint and dataFindingsVoice service requirementsThe VTOA service necessity recognizes the section service to be supported and identifies how the service should be delivering8 . The network operator might wish for to let precisely vocalise affair over ATM in a circuit mode suited to consideration of the delivered vocalization superiority . This can be proficient by bureau of the AAL-1 CES for mapping DS1 /E1 and DS3 /E3 circuits on an ATM practical circuit network using a stable bit rate (CBR ) over a premature ventricular contraction /SVC association . other than utterance merchandise can be transported by gist of AAL-2 with portion compression and clam up repression as changeable bit rate (VBR transfer . AAL-2 lease for the multiplexing and transport of minute variable sized voice packets with quite a few voice compression options particularly G .727 , G .729 , and G .723 .1--at bit rates vary from 32 kb /s to 4 .3 kb /s per channel . By transporting voice over AAL-2 with compression and silence repression enables turn multiplexing and consent to enhanced bandwidth utilize .8 ATM practical circuits for voice craft can be recognized as PVCs based on predictable service demands or they can be set up energetically as SVCs on a per-call foundation The PVC advance uses ATM as a method of providing drawers among the itinerary network .8 On the contrary , the SVC move toward more productively uses the transmission and switching competence of the ATM network and provide the network resources to be divided by additional barter produce by data and multimedia infrastructure . 8Network designFounded on chosen network structural design and all the aforesaid(prenominal) network design inputs , the plan of network plan is to lay out a system topology identifying the place and dimension of the nodes Network plan too lays out the connection services interconnecting the applicant nodes such that the calling require from dissimilar services between the nodes can be carry out . The design is made effective by reducing a certain subprogram function , ofttimes the of the resulting network design . A huge network often is segmented into access and prickle out-of-pocket moreover to architectural necessities or to an effort to adulterate the design s difficulty . This naval division makes a near-optimal other than plastic network design8Backbone network designThe objective of headstone network symbolizes is to gain a minimum- equal keystone network that can hold up the transport of inter-edge node relations derived from the right to use network s devise . The backrest network plan performs exceed design on both new and recent gettable back nodes and It take places the connectivity and association aptitude among the gumption nodes and comprise such contemplation as direction-finding constraints , the numeral of hops , and additional QOS requirements to permit enough switch-to-switch bandwidth to support network command .8 The design neckcloth features here is a classical network optimization problem . It requires finding a network topology having convinced link capability such that all the art difficulty is issue and the no simultaneous employ of services by subscribers , the full amount bandwidth obligation is decrease . As a result , an overbooking feature is exercised in prickle trunk engineering to account for this lessening . At last , the plan tool productiveness is analyzed for performance proof , parameter compassion , and price examination 8AnalysisPerformance analysisThe presentation limit used for assessment purposes are the stoppage jitters for voice profession and the packet unloosen relation for information craft . Following the initial network design is finished the network s presentation is investigated and If the performance of the mean network does not get together the performance purpose for dissimilar services , intend parameters (such as utmost link employ or number of hops ) are attuned and a innovative plan is shaped so this procedure is reiterate until the mean network get together the service performance aims . 9Sensitivity analysisThe purpose of sensitivity examination is to conclude whether a knowing network can withstand a quantity of barter demand variation beholding as the projected traffic is habitually probable with some discrepancy even though the designed network is commensurate to handle the forecasted demand , any disparity in traffic demand , service mix , or cost replica may alter both the topology and cost of the intended network The consequences from compassion analysis are used as one of the criteria for final proposals . 9Cost analysisIn fact network infrastructure is founded on the optimization of a controlling condition-- in general , the cost of network services and equipment . The full cost of the planned cost-optimized network is premeditated based on the network s topology and relation ability tariff cost arrangement (if leased lines are used , and the cost pattern of ATM /IP tools . The reckoning of the network s capability cost is comparatively licated using either the tariff cost method or any of more than a few different processes to decide this cost according to network operators favouritesIP Network architectureVarious lucre service providers are drift in genius providing voice service on their Internet protocol book binding network and in this latest incorporated architecture such voice traffic initial will be routed end-to-end the end-office switch to an Internet telephony server /gateway (ITS , and then ratified through the IP backbone networks9 The greater half of the network structural design is suitable for the voice-over-IP application and as voice traffic is routed throughout the end office summarize in RTP /UDP /IP in the ITS gateway , and authentic in the shoes of an IP sitting in the IP central part network . The gatekeeper executes the regeneration between SS7 and the IP academic term administration protocol to set up sessions vigorously for windowpane pane the voice data traffic9ConclusionIn a nut outwit we find that with the expansion networking protocols and Internet and data services , it is classically accepted by the customers and end-users . The fundamental network must be packet based and what is not yet clear is the sex act merits of the diverse packet technologies in provided that manifold services with slippery traffic demands and different levels of network presentation to clientele . Every one voice telephony service providers are paying attention in tactful the business features of transporting their revenue-generating services to a network foundation on ATM or IP skill Since we pointed out , a quantity of central features must be considered in making these choices . The standard companies with diffusion in the high-end market will have their network suppliers opening to centre their brilliance on the mid-size companies and impulsively , this is the accurate way . On one occasion the big companies are smooth with these elevated systems , it s only expected that they wait for their suppliers-chain to be able to perform industry contact with these systems . prognosticator approximation of such companies are .2 million to .4 million companies mid-sized companies in the UK that are ready for venturing the software skill in the market of at the moment . 9The VTOA examination presented here recognized nest egg occasions in the backbone network . The replicated network takes into translation a genuine network diagram and traffic infer for a distant backbone network .
