Attempts to save costs are driving enterprises toconverge their voice, video and data traf c over a packet-basedwide area network (WAN) service. In addition, successful andcost-effective deployment of information and communicationtechnology (ICT) has moved into the spotlight as a myriad of information technology (IT) applications now extendbeyond a single site and more and more business is beingdone electronically. Enterprise networks are becoming themost fundamental underpinning of business and organi-zational success.These dynamics are pushing enterprises to consume everincreasing amounts of bandwidth as they interconnect moreand more local area networks (LANs) and require higher-speed access to the Internet. Business connectivity servicesdelivered over private line and frame relay networks areexpensive and are stretched to the breaking point as ITapplications require increased bandwidth. Existing networkinfrastructures are not conducive to supporting the conver-gence of voice, video and data services onto a single network.More than ever before, enterprises need WAN services toenhance the bottom line. With Ethernet access to user-centricWAN services that are enabled by an intelligent network, the enterprise has the service choice and the service controlneeded to achieve operational excellence. Service providers like MASERGY are introducing new andinnovative WAN service offerings that leverage user-centricmultiservice routing platforms from suppliers like Alcatel to meet and exceed enterprise service requirements.The Chief Information Of cer s ChallengeThe world of an enterprise Chief Information Of cer (CIO) isbecoming more complicated, involving technical, organizationaland economic dynamics that impact market timing, organiza-tional adaptability and institutional risk aversion. In today shighly competitive market place, the abundance of solutions,limited resources, ever changing business requirements and the interdependent nature of these challenges can be overwhelming.The abundance of networking solutions and complexity isgrowing exponentially. Despite the business failures over thepast few years, we see more equipment, types of equipment,operating systems, applications and network environmentsthan ever before. Resources are becoming even more limitedas enterprises strive for ef ciency. However, this push forsavings comes at a cost. As operating environments becomeheterogeneous with a mixture of legacy and advanced systems,the expertise required to manage these environments becomeseven greater. The business requirements driving the enterpriseare continually changing. CIOs must constantly respond toexternal and internal needs, such as security, access, perfor-mance measurement and shifting corporate priorities. CIOsmust ensure the reliability and redundancy of networks,equipment and operating systems. Given the interdependentnature of these challenges and the advanced strategic role of technology, the cost of failure could be catastrophic. Don t try this on your old network. " An eight-fold increase in backbone capacity at no extracost compared with frame relay." International VOIP calls saving  163,000 per year."

WAN services are needed to support coreICT applications that extend beyond a single site to connectcustomers, suppliers, branch of ces, data centers and remoteworkers. The existing frame relay or private line WAN servicescan no longer get the job done. Today s legacy data servicesare often not cost-effective, have no practical ability to integratevoice, video and data into a converged solution, have constraintson bandwidth exibility and have not met enterprise supportexpectations. In addition, videoconferencing applicationsusing an integrated services digital network (ISDN) serviceare plagued with poor quality and cumbersome call setupprocedures.Universal Ethernet Services for Customer-Controlled Application PerformanceUntitled Document> 2   ALCATELNext, there is the issue of the networking protocol. Whilemost internal LANs are implemented using Ethernet, theremay be legacy protocols such as systems network architecture(SNA) or Digital Equipment Corporation networking protocol(DECnet) in use. These protocols support high-priority legacyapplications that require ongoing maintenance.Then there is the voice challenge. Enterprises have developedtheir own telephony staff, separate from the data staff, tohandle voice. Now that voice over IP (VoIP) has become morecompelling from a cost perspective and is technically muchmore viable, CIOs must factor voice into the WAN service mix.In spite of the market hype over VoIP, many CIOs perspectivesare still tainted from the unsuccessful attempts at convergencewith VoIP across frame relay.Finally, with many applications competing for the same band-width, there are the performance requirements from theinternal user community. Business-critical applications suchas customer relationship management (CRM), enterpriseresource planning (ERP) and supply chain management (SCM)solutions have become the lifeblood of the business. The CIOdepends on these business-critical applications to drive speci ccorporate objectives. The key indicator of success of a com-pany s IT initiatives is the performance of its business-criticalapplications. Failure or underperformance of these criticalapplications is not an option.These complex, critical requirements have overwhelmed theWAN. To make matters worse, there is a chief nancial of cerwho has read how all of this new technology will take thecompany to the next level and reduce costs in the process.What is a CIO to do?WAN Service OptionsNew WAN service options that can signi cantly reduce ICTcosts and address all the critical CIO challenges are IP virtualprivate networks (IP-VPNs) and virtual private LAN services(VPLS). To the enterprise, an IP-VPN is a routed service,performed at Layer 3 of the open systems interconnection(OSI) model, which forwards traf c based on the IP address.VPLS is a bridged service, performed at Layer 2 of the OSImodel, which forwards traf c based on the media accesscontrol (MAC) address. MASERGY, as well as supplying Universal Ethernet Services for Customer-Controlled Application PerformanceVideoconferencingPBXBusiness Application ServersFTP ServerPOPPOPInternet UsersPSTNLocation AVideoconferencingPBXBusiness Application ServersFTP ServerInternet UsersPSTNPSTNPOPPOPInternetLocation BFigure 1 - MASERGY s Customer-Controlled IP-Based MPLS NetworkUntitled DocumentALCATEL 3   >IP-VPNs, has the rst commercial deployment of VPLS services in North America. Both Layer 3 VPNs (e.g., IP-VPN)and Layer 2 VPNs (e.g., VPLS) are capable of enforcing strictquality guarantees on real-time voice and video applicationsand business-critical data applications, as de ned by a servicelevel agreement (SLA). Figure 1 provides a sampling of theenterprise applications MASERGY can support.As enterprises begin to replace their aging legacy enterprisenetworks to provide better application support, it becomesimportant for the CIO to understand the needs of the enter-prise and the ways in which the appropriate WAN solution can best support those requirements. An IP-VPN supports onlyIP-based applications, with the enterprise and service providersharing the routing responsibility, a potential network complex-ity issue for the enterprise. This means that IP addressingdecisions require coordination with the service provider. VPLSis protocol-independent it can support both IP and non-IPapplications and gives the enterprise complete control over network routing. Regardless of the chosen technology,WAN services must support exible bandwidth and they mustensure acceptable performance of all applications used by the enterprise.The choice of a service provider partner to provide the WANsolution is critical. The decision should consider the serviceprovider s experience and ability to provide both IP-VPN andVPLS service options to best meet the needs of the enterprise.Service providers that try to force a solution based on theirtechnology severely limit the performance of the networksolution. MASERGY puts meaning in the service part of serviceprovider. The company is a true technology partner one committed to LifeCare s ongoing success. ZEKE ZOCCOLI, CHIEF INFORMATION OFFICER, LIFECARE MANAGEMENT SYSTEMSUser-Centric WAN ServicesIn the face of relentless competition, enterprises have come torely on WAN services to cut networking costs and to supportthe ICT applications that drive sales, improve customerrelationships, train staff, and simplify procurement. A user-centric Layer 2 or Layer 3 VPN service gives an enterprise a competitive edge with the service choice and service controlneeded to achieve operational excellence, while leveragingconvergence to reduce costs. Having access to both Layer 2 or Layer 3 options makes it possible to tailor a solution tomeet the unique needs of the enterprise. Service choice gives an enterprise Ethernet, frame relay andprivate line connectivity options to access Layer 2 and Layer 3VPNs supporting not only data, but also VoIP and video servicesover both public and private networks. Multiple service optionsgive enterprises the exibility to select the service that bestsuits their application requirements and networking methodol-ogy. Furthermore, application awareness can be used to tailora VPN service to meet the performance needs of any mix ofapplications, including the support of business-critical appli-cations. With application awareness, the intelligent networkhas knowledge of the applications the enterprise is using and takes action to treat these applications appropriately.Performance metrics are de ned in the SLA, and can includebandwidth exibility, service availability, latency and jitterthresholds.Service control gives the enterprise real-time, web-based toolsto monitor network performance, adjust service parametersand simplify troubleshooting. Examples of service controlfeatures include the ability to:>  View network usage> Monitor the SLA performance of individual applicationsacross the entire network or view application performanceby de ned groups> Receive alerts based on application metrics to preventperformance degradation> Perform non-intrusive remote data analysis for completeend-to-end service assurance> Drill down for individual level details on deviceperformance> Order new services> Prioritize applications> Adjust service pro le to increase bandwidth on demand or change billing options> Generate standard or custom reports on the performance of applications for distribution to internal clientsUniversal Ethernet Services for Customer-Controlled Application PerformanceUntitled Document> 4   ALCATEL We have been impressed with MASERGY s network servicemanagement capabilities and their innovative range ofofferings. STUART PALLANT, HEAD OF IT INFRASTRUCTURE AND OPERATIONS, STANDARD BANK LONDON LTD.Cost savings in the range of 30 percent to 50 percent or moreare often achievable by converging voice, video, data andInternet traf c over a single connection. By bundling servicesover one access connection, enterprises rid themselves ofmultiple dedicated network connections from multiple serviceproviders. Costs are also lowered through greater bandwidthef ciency. By designing the WAN service for desired applicationperformance rather than peak demand, business-critical appli-cations such as CRM, ERP and SCM are allocated enoughbandwidth to meet their peak requirements, while at the sametime engineering non-critical applications such as emailand web browsing to meet an acceptable level of perfor-mance. Finally, greater bandwidth ef ciency is achieved bypermitting lower priority applications to jump in and ll thevoid when business-critical applications go idle. The idea is to use all available bandwidth at all times, with delay-sensitiveapplications like voice and video, in addition to high prioritydata applications, always at the head of the line. End-to-endquality of service (QoS) is the key to delivering consistentperformance for all applications and to optimizing bandwidthef ciency.The foundation of user-centric services is the Service-AwareEdge (SAE) architecture. As shown in Figure 2, SAE has theintelligence to consolidate services that today are beingdelivered over multiple disparate networks. User-centric WANservices have full multiservice capability, allowing end users tobe connected regardless of their technology preference. Theseservices also enable the enterprise to receive all of the servicesover a common access, reducing cost and complexity. User-centric WAN services can support thousands of services forhundreds of thousands of users and take into considerationthe ability to deliver the services faster, with fewer errors andat a lower cost without compromising the value of the service.Now the service provider has a solution that can truly addressenterprise needs with better pricing, better applicationperformance and more exibility in the service mix.Universal Ethernet Services for Customer-Controlled Application PerformanceFigure 2 - Consolidation Bene ts of the Service-Aware Edge ArchitectureHQPSTNRASPSTNVoiceISDNVideoInternetEnterprise PrivateWANWebHosting10M TLSCanadaT1 FR10M10M TLS10MDS3PlanoDS3AntwerpDS34xT14xT15xT116xBRI100MEthernetT1-DCPartnersTodayConsolidatedService- AwareEdgePSTNInternetWebHostingPartners"  8 network services"  7 vendors"  9 bills"  12 access fibers"  16 coppers pairs"  1 user-centric WAN service"  1 vendor"  1 bill"  2 access fibersHQUntitled DocumentALCATEL 5   >Intelligent NetworkingUntil now, the cost savings through convergence have been anunful lled promise from telecommunication service providers.First offered with the introduction of private line WAN services,convergence now comes to full fruition with MASERGY sIntelligent Transport product, enabled through a partnershipwith Alcatel. The MASERGY network uses the next generationof multiprotocol label switching (MPLS) multiservice edgerouters supplied by Alcatel.As shown in Figure 3, Intelligent Transport provides trueconvergence and complete service exibility by enabling theenterprise to select up to ten virtual connections (VCs) perport, with multiple service offerings over a single transportconnection. This is achieved by provisioning a MASERGYIntelligent Bridge at each enterprise location. The MASERGYIntelligent Bridge delivers Ethernet to the enterprise locationusing multiple virtual LAN (VLAN) identi ers over ber atnative Ethernet speeds or over a serial connection at T1, T3 orE1 line rates. For unmatched service exibility, the enterprisecan choose the following VC options, which can be combinedon a native Ethernet connection or a serial link:> Private IP   an RFC 2547bis-based Layer 3, any-to-anyprivate service, with Layer 2 type security with full QoS> Public IP   Layer 3 connectivity with full QoS> Private Link   a Layer 2 VPN tunnel with full QoS> VPLS   fully meshed Ethernet LAN connectivity with full QoSUniversal Ethernet Services for Customer-Controlled Application PerformanceTH E S E RV I C E - AWA R E E D G EAs service providers attempt to reduce the number of net-works by converging onto a single technology, they nd that their current platforms lack the intelligence to support all of the services they would like to deliver. To bring thekind of intelligence to the edge of the carrier networkneeded to deliver user-centric, value-added services forenterprise, consumer and mobile network users, Alcatel has introduced the Service-Aware Edge (SAE) architecture.For enterprise users, the SAE architecture provides thebuilding blocks to allow the de nition of enterprise-speci cservice bundles, a capability not commercially possible with today s network architecture. Data connectivity servicesthat carry nancial transactions, handle customer outreachinformation or facilitate just-in-time production need differentpriority than data services carrying e-mail. The intelligenceof the SAE is used to create user-centric WAN services with application awareness that gives them the ability toprioritize applications based on the user requirement andcan be tuned to deliver the performance speci c to therequirements of the applications running over it. Enterpriseusers get more than just a bit pipe, they get a network that is optimally engineered to the performance of theirbusiness applications.HeadquartersRemote SiteExtranet PartnerRemote SiteExtranet PartnerPrivate IPPublicInternetPrivate IP(RFC 2547)VirtualPrivate LAN (VPLS)Public IPVPLSPrivate LinkNetworkFigure 3 - Overview of the Intelligent Transport Virtual Connection OptionsUntitled Document> 6   ALCATELAs depicted in Figure 4, Intelligent Transport enables ve ser-vice planes: voice, video, critical, priority and normal. Theyare enabled on the access port and are not speci c to the VC.This means that an enterprise with a 768 kb/s video connectionover a public VC and a private VC can use the bandwidth over the public VC, the private VC, or split with 384 kb/s overboth the public and private VCs. The overall port is limited to768 kb/s of video regardless of which of the VCs the traf c ispassing through.Alcatel s service routing technology is at the foundation ofMASERGY s Intelligent Transport service offering. MASERGYrelies on the Alcatel 7750 Service Router (SR) to deliver criticalnetwork services with industry-leading functionality thatincludes VPLS; sophisticated QoS management; a service-aware operations, administration and maintenance (OAM)toolkit; and advanced data collection.The Alcatel 7750 SR is an integral part of MASERGY s IntelligentTransport service, which enables the enterprise to get Layer 2(VPLS) and Layer 3 (RFC-2547bis) VPNs across the same circuit,on the same device. The Alcatel 7750 SR features hierarchicalQoS (H-QoS) management, which provides sophisticatedtraf c management across different services and VLANs. H-QoS shapes, polices and manages all traf c owing throughthe hub, ensuring that all enterprise traf c is properly queuedand transmitted by priority through the MASERGY network.The Alcatel 7750 SR also has a comprehensive service-awareOAM toolkit for service assurance and rapid troubleshootingon a per-service basis to maximize service uptime. The toolkitincludes a service mirroring feature that mirrors traf c on aper-service basis to allow an operator to see the actual traf cfrom any enterprise site, from the MASERGY networkoperations center.

To meet the WAN service require-ments of value-demanding enterprise customers,a solution must cost-effectively combine asubstantial increase in the density andforwarding performance of an edge routerwith the processing capabilities typical of anadvanced IP services platform. The Alcatel7750 SR is the ideal product for this market. The Alcatel 7750 SR demonstrates that ascalable routing platform can be deliveredwith the deep packet processing and queuing required to enable multiple services with per-service QoS, without compromising theforwarding performance, density and cost of the system. The Alcatel 7750 SR combinesthe exibility and investment protection of afully programmable forwarding plane with a system architecture that delivers outstandingport density, system scalability and low cost.The result is a scalable IP/MPLS service router that enables network operators to cost-effectively deliver a wide variety ofdifferentiated services from advancedInternet services to VPLS and IP-VPNs over a single IP/MPLS network infrastructure. Support for a wide range of enterpriseservices, coupled with a comprehensiveOAM&P feature set, differentiatesAlcatel s Service Routers from othervendors and delivers tangible value toservice providers. Based on our researchwith service providers worldwide,Alcatel s Service Routers are clearlyaligned with the most challengingnetwork problems carriers face today. MARK BIEBERICH, SENIOR ANALYST,COMMUNICATIONS NETWORK INFRASTRUCTURE, THEYANKEE GROUP Untitled DocumentALCATEL 7 >Finally, the Alcatel 7750 SR has the capability to process andreport on huge amounts of data. With the ability to separatethe accounting and command line interface statistics, theAlcatel 7750 SR is a natural point for data collection. No otherservice provider has enabled this degree of integration, whichenables the enterprise to view comprehensive usage statistics,change bandwidth and add services dynamically, usingMASERGY s award-winning Service Control Center (SCC). Universal EthernetOriginally developed as a protocol for linking computers,Ethernet has proven itself as the de facto LAN standard. Most, if not all enterprises have built up signi cant Ethernetnetworking staff expertise. Today, leveraging Ethernet s cost-effectiveness, multiservice attributes, high-bandwidthcapabilities and simplicity, Ethernet local loops have beendeployed in metropolitan areas, especially in Europe andacross most of Asia, to enable innovative WAN service options.Ethernet has emerged as the technology of convergence forenterprise WAN services thanks to the familiarity of the tech-nology, coupled with its high bandwidth and QoS capabilities.The widespread use of Ethernet and continuous technologyadvancement have combined to drive down port costs, makingEthernet a cost-effective alternative to asynchronous transfermode (ATM), frame relay and private line WAN interfaces. In addition, technological advancements allow an Ethernethandoff to a WAN service to support multiple traf c types such as voice, video and data with full QoS guarantees. Thenew carrier-class Ethernet can support SLAs that are on parwith those available for frame relay and private line services,in terms of availability and performance guarantees, at a verycompelling price point.Ethernet has the unique ability to meet the new WAN servicerequirements. As cutting edge ICT applications require increas-ing amounts of bandwidth, and as enterprises interconnect to more and more distant LANs and data centers, bandwidthrequirements continue to climb. Ethernet not only has thehigh bandwidth capabilities with speeds ranging from 10 Mb/sall the way to 1Gb/s, Ethernet is also available in ne incre-ments. Bandwidth granularity means that enterprises pay only for the bandwidth they need, for further cost savings.The simplicity of Ethernet quickly translates to operationalsavings for enterprises as they network with a technology they are very familiar with. Since there is no need to convertprotocols, this simpli es the enterprise network and also leadsto reduced troubleshooting and training costs.WAN Service Selection ExamplesKnowing that each enterprise segment is unique and that each ICT application has speci c performance requirements,MASERGY can tailor WAN services to better meet the speci cbusiness objectives of the enterprise CIO. Here are twoexamples:Customer Case #1: Financial Services EnterpriseWhat characterizes nancial services enterprises? In mostcases, they support numerous applications and are verysensitive to networking delays caused by latency. There maybe a large number of private line circuits in a hub-and-spokearrangement, which in the past was able to handle the traf cbandwidth generated by trading or other nancial transaction-oriented applications. There may be some SNA or DECnettraf c in addition to Ethernet. Voice and video may reside onseparate infrastructures. The network is probably under greatstrain, unable to cope with the increasing bandwidth demandsof the business. The cost of even a simple installation and/orupgrade to the private line circuits is proving to be veryexpensive. For reasons of security and control, the IT staffwants to retain WAN routing control as they move to newWAN service options.In summary, the service requirements of the enterprise are:> Critical traf c such as  nancial transactions (e.g., InteractiveFinancial eXchange), CRM, ERP and videoconferencingmust be prioritized over web browsing.>A meshed solution is desired to implement a redundantinfrastructure and to absolutely minimize the time to repairfor any outage, as each minute of down time results in hugerevenue losses.>All applications must run over a single connection at each site.>For security purposes, the enterprise does not want toshare routing information or have it controlled by theservice provider.>Flat-rate billing is required on a per-application basis (no usage fees). >Ethernet must be used for new sites with  ne granularity of access bandwidth.Universal Ethernet Services for Customer-Controlled Application PerformanceUntitled Document> 8 ALCATELGiven the service requirements, the CIO and his team have tomake a decision. More private lines would not be acceptablefrom a cost or application performance perspective. A framerelay implementation would not meet the real-time require-ments for data responsiveness. ATM may work technically, but would be a very expensive solution not well understoodby the staff.The service technology option selected is MASERGYIntelligent Transport with VPLS:> Ethernet is a technology that is well understood by thenetworking staff.>Higher priority traf c has guaranteed bandwidth whilelower priority traf c uses full bandwidth when criticaltraf c is not present.>The solution supports networking of SNA and DECnet traf c. >The service offering provides 99.99 percent uptime,proactive restoration of network outages and pre-commissioning of services.>Cost savings are realized by providing backup capacity to critical applications only.>A customized service bundle supports on-demand change options.>There are no WAN distance fees.The service selection rationale for VPLS is as follows:>VPLS provides multiprotocol support for all Layer 2protocols (e.g., SNA) with a much easier migration paththan with a Layer 3 IP solution.>An SLA guarantees performance of the service and allowslower priority traf c to burst to the full rate of eachconnection offering a truly converged solution.>The service solution offers the advantages of open shortestpath rst (OSPF) transparency and greater security as therouting information does not have to be shared with theservice provider.>Cost savings are realized by providing backup capacity onlyto critical applications and through very high utilization ofnetwork links.VPLS can be a compelling solution for any enterprise withsimilar needs. Customer Case #2: Retail Services EnterpriseWireless Fidelity (WiFi) access, based on IEEE 802.11, is becom-inghot for retail establishments to attract and retain customerswhere they can enjoy a relaxed time while consuming theproducts offered by the establishment (e.g., at an Internet caf or airport lounge). The problem with conventional approachesto this problem is that each location requires two circuits: onefor the enterprise s private traf c and one for public Internetaccess. Why not combine these services onto one access circuit?With MASERGY S Intelligent Transport product, you can.The service requirements are:>The enterprise needs to connect each store to theheadquarters location with a private IP-VPN and they needto connect each store to the public Internet to offer WiFiInternet access for customers. >The enterprise must be able to add/remove newstores/suppliers quickly.>Ethernet must be used for new sites with  ne granularity of access bandwidth.>The enterprise needs a standard cookie-cutter approach for service de nition, with rapid service provisioning andimplementation..
