Additionally MPLS does not solve carrier needs for Layer 2 coverage, which is why created the (MEP) and Extended Virtual Wide Area Network (evwan), a gateway to realizing the full potential of MPLS; a cost effective and efficient method of aggregating multiple carrier networks over a single Network to Network Interface (NNI). The Challenge Legacy off-net connectivity solutions increase capital and operational expenditures, time to market and infrastructure investment risks, while limiting the potential for global reach. The Opportunity Access to s (MEP) and an option to implement an evwan for fully transparent Layer 2 Ethernet services over its Enhanced Ethernet Network to Network Interface (eenni). The Benefits Access to the MEP and evwan, enabling fast and seamless connectivity to global markets and facilities that have traditionally been costly or difficult to manage and the ability to add end-toend Quality of Service (QoS) and Committed Information Rate (CIR) which can be policed throughout the core and down to the customer premise. Dedicated Internet Access (DIA) can be added and kept locally to any location world-wide. A single eenni offers access into hundreds of markets and tens of thousands of lit buildings globally while reducing infrastructure investment and market risks. Transparent Last Mile Access Carriers can connect enterprise customers in global markets via Type 1 and Type 2 access via Layer 3 on the MEP and via Layer 2 using evwan Last Mile Ethernet Access speeds ranging from 1 MB to 10GIG or Ethernet over Time-Division Multiplexing (EoTDM) / Ethernet over Synchronous Optical Network (EoSonet), traditional TDM converted to Ethernet, as well as Next Generation connectivity such as 3G and 4G can also be used for access. Implementation: evwan Layer 2 Connecting locations into evwan using Virtual Local Area Network (VLAN) transparency is accomplished via point-to-point Ethernet, EoTDM, and EoSonet EoTDM Layer 2 private circuits. Implementation: MEP Layer 3, MPLS Carrier customers can choose to utilize existing MPLS network connections, in place of new private circuits. Summary The increased flexibility and scalability from the MEP not only decreases Total Cost of Ownership (TCO) but also increases the potential for greater and quicker returns. PAGE 2

4 Introduction According to Infonetics Research s June 2010 report on worldwide MPLS/Internet Protocol Virtual Private Network (IP VPN) and Ethernet Services Market, the Ethernet market generated $20.8 billion in 2009, a 23% jump from 2008 and the MPLS market increased by 12% during the same period. The MPLS market has entered the growth stage of the product lifecycle and demand, of which, they forecasted the combined growth to be a healthy $68.2 billion by As traditional services such as Asynchronous Transfer Mode (ATM) and Frame Relay are on the decline, Layer 2 and Layer 3 MPLS VPN services are quickly rising in demand for fully meshed networks with strong Service Level Agreements (SLA s) and Quality of Service (QoS) to manage the convergence of voice, data and video applications. Until recently, telecommunication carriers have focused on selling their own product, on their own network. Traditionally when the sales team has an opportunity outside the core network footprint the options to fulfill the request are limited. Some carriers simply turn the opportunity away because it is outside the coverage area, others spend time and money attempting to procure those expensive assets from 3rd parties. Often making matters worse, operations has to face the inherent network integration obstacles associated with connecting to 3rd parties. To deliver these types of solutions, carriers have been forced to purchase legacy and expensive off-net connectivity solutions, in many cases serving a one-time purpose. Worse, most carriers have no solution at all to support off-net locations where an expensive Point of Presence (PoP) augmentation is simply not justified. Yet, the marketplace is demanding a growing need for telecommunication carriers to offer their enterprise business clients connectivity solutions in a greater number of locations; moreover, those off-net locations need to support an ever-expanding number of real-time, mission critical applications. Enterprise businesses demanding increased bandwidth in conjunction with Voice over Internet Protocol (VoIP) and other real-time applications are quickly changing this landscape. An increasing number of carriers now demand network services both nationally and internationally where they don t have access to cost effective connectivity; oftentimes needing to provide solutions that can meet the strict needs of their customers critical real-time applications where those customers are no longer willing to accept the unpredictable nature of IP-based virtual private networks. has introduced its (MEP) as a solution to meet this growing demand where realtime and mission critical applications are delivered over a single Enhance Ethernet Network to Network Interface (eenni) via Layer 3 MPLS and/or Layer 2 on the Extended Virtual (evwan) to leverage its interconnections and aggregated carrier networks around the world. Carriers of all sizes can now take advantage of gaining access to off-net network access globally without having to invest in deploying new PoP s, signing new Master Service Agreement (MSA s), making multiple new commitments or taking multiple new NNI s, etc. Additionally, carriers can also have access to services that support real-time and mission critical applications for their demanding enterprise customers. s U.S. Border Gateway Interconnections NYC Philadelphia Chicago Denver Atlanta Los Angeles Dallas Border Gateway Interconnects are connected via diverse 10GB Private Lines. Border Gateway Interconnects provide services to the surrounding metro markets. Metro markets are connected on demand. PAGE 3

5 While the MEP was built to allow the construction of seamless MPLS networks across multiple carriers, the platform also offers the ability for carriers to purchase evwan, a fully virtual Wide Area Network (WAN) offering completely transparent Layer 2 Ethernet services, and all of this if offered over our single eenni, Dedicated Internet Access (DIA), QoS / Class of Service (CoS), can also be customized to meet the bandwidth, engineering and performance requirements. The Challenges In today s marketplace where enterprises are expanding rapidly into non-traditional markets, both nationally and internationally, telecommunications carriers are trying desperately to expand their network coverage to meet enterprises needs for a robust global network that can support ever-demanding, realtime applications, like VoIP, video over IP, Enterprise Resource Planning (ERP) and enhanced Point of Sales (PoS) systems. The explosive growth of these mission critical applications dramatically increases constant bandwidth requirements, which, in turn, cause carriers to expand and/or upgrade their networks in order to stay competitive and retain enterprise clients. Many times, responding to these network demands proves extremely costly, inadequate and could result in carriers losing both capital as well as market share. MPLS network coverage has traditionally been growing solely within individual carrier network providers footprints. While the need for carrier interconnection has risen rapidly, options have been limited to complicated single NNI s and constrained by the exorbitant time and cost of such an implementation. Similarly, smaller and regional carriers that need to cover the same areas, as their larger competitors, cannot assume the same level of liability associated with the build-out of their Last Mile network, especially when there is no guarantee of market penetration or profitability. Furthermore, as is the case with any carrier, Last Mile is simply a means to connect their customer to its network and then generate revenue and value based on actual network services. Last Mile is hardly seen as a profit-making portion of the network but is a necessity to start generating revenue on other core network services. With the evolution of the Internet, carriers and Internet Service Providers (ISP s) responded to the demanding enterprises and began deploying MPLS as a transport medium instead of transporting data over legacy networks such as ATM / Frame Relay and privately owned infrastructures. This allowed service providers to offer enterprises a lower cost alternative to legacy networks. While traditional private Layer 2 networks typically deliver better network performance, uncompromised security, and QoS, they are often more expensive. MPLS developed to bridge the gap between costly legacy private network connectivity and clumsy Customer Premise Equipment (CPE) based VPN solutions; allow both enterprises and carriers to reap the benefits. Still, the challenge remains; carriers need to bring customers to their network cost effectively, quickly and easily in order to provide them scalable and profitable network based traditional and enhanced services. The Opportunity In an effort to limit technical and financial obstacles caused by carriers most ubiquitous problem, lack of coverage, IPNET- ZONE has introduced the MEP. With a single connection to the MEP, service providers can have access to multiple MPLS networks globally and experience MPLS the way it was originally intended as a carrier to carrier service. By leveraging London Los Angeles New York Dubai (Future) Mumbai (Future) Hong Kong Sao Paulo (Future) s Global Border Gateway Interconnections PAGE 4

6 revenue opportunity and productivity while vastly reducing interconnection costs, operating expenses and time to market. s architecture addresses QoS/CoS and flexibility; limitations of traditional networks. It provides a fully managed private network service enabling businesses to securely share mission critical data, voice and video applications between multiple locations, without touching the Internet. Customized to meet each Carrier s unique needs based on metrics such as size, geographic spread, current bandwidth demands, and growth projections, MEP is ideal for carriers that require the flexibility and cost advantages associated with having a PoP in every market and a lit building everywhere their competitor has one. All this without having the burden of dealing with multiple carrier relationships while reducing capital and operational expenditures, and enjoying a significantly faster time to market. The scalability and flexibility, of the solution, finally make highperforming converged networks a viable option for carriers and service MEP providers. At each Border Gateway Interconnect (BGI), the MEP Fabric exists to maintain a single MPLS network across multiple carriers for a single client. Each MPLS circuit will belong to a unique Virtual Routing and Forwarding (VRF) with its own label tagging on a per provider basis. The MEP can inject the VRF into multiple MPLS service providers and multiple VRFs back into the single eenni. can provide a single platform that manages the carrier s carrier MPLS/VPN solution for service provider. The benefits of our solution can help service providers to leverage other service providers footprints thus reducing capital and operational expenses, managing carrier s carrier services and relationships, and increasing the cost effectiveness of the last mile access. MPLS Core s eenni QoS/CoS over the MEP also eliminates bandwidth sharing and concerns about latency or jitter issues. Network capacity will always be available for applications because there is no sharing with other carriers and traffic is dynamically prioritized bi-directionally, into and out of the network core as well as the customer premise. Carrierclass service is fully guaranteed because MEP supports all QoS/CoS features within the network core and, more importantly, across all Last Mile connections. evwan Layer 2 Core A Single NNI provides access to both products. Layer 2 and Layer 3 Class of Service is available. eenni accomplishes this superior solution with an innovative core architecture that is fully redundant and guarantees application performance and customer satisfaction. The solution is also dynamic, so it can easily be scaled and modified to suit the real needs of the provider using the network. The Benefits The MEP is the construction of seamless MPLS networks across multiple carriers. This solution enables fast and seamless connectivity to global markets and facilities that have traditionally been costly or difficult to manage. MEP is delivered over a single eenni, which is a layer 3 MPLS hierarchical VPNs providing IPv4 VPN services across multiple Autonomous Systems. The option to implement an evwan for fully transparent Layer 2 Ethernet services over the eenni is also supported in addition to its inherent benefits of delivering transparent Layer 2 Ethernet services. QoS & Committed Information Rate connects all customer sites and all backbone nodes with the ability for QoS to be added end-to-end. This method, unlike typical IP networks, allows to carve out bandwidth for each customer and thus ensure high data throughput, low latency, minimal to zero data loss, and negligible jitter. All circuits within the MEP connect directly back to an core node and are terminated into a VRF dedicated to the specific customer. All core nodes are interconnected via a fully redundant and highly resilient backbone with dedicated bandwidth on a per customer basis. PAGE 45

7 4 Classes of Service s Class of Service Class of Service Priority Sensitivity Application Real Time 1 Very Sensitive VOIP Critical 2 Tolerates slight latency & jitter Video Priority 3 Special Treatment Databases Standard 4 Tolerates moderate latency & jitter Web Browsing Priority CoS All circuits within the MEP and evwan are enabled with bi-directional priority based upon customer defined type of service classification. Priority schemes are customized individually for each customer and Last Mile link to meet application usage needs and to prevent flow issues. This priority is enabled in the MEP and evwan core through policing, marking, scheduling and traffic shaping configurations applied specifically to each Last Mile circuit. For example, makes VoIP and video reliable and clear by ensuring the highest throughput for voice calls and video, while scaling back bandwidth for lower priority data. CoS is enforced from end-to-end across a customer's entire network, ensuring that voice traffic is prioritized and that bandwidth is dynamically scaled back for lower priority applications. This type of bi-directional priority cannot be accomplished using customer premise routers alone, but must also be enabled on all core backbone links and be fully customized to meet individual customer priority schemas. Intelligent routers throughout the core are what allow true CoS enforcement. Failure to build this type of end-to-end CoS-aware infrastructure into the network is one reason that other solutions often fail to provide the CoS they promise, and why customers are unhappy with the performance of their network, specifically regarding real-time, and mission critical traffic. All Last Mile and core links are enabled with four Priority Queues: Real Time, Critical, Priority, and Standard. The Customer Edge (CE) / CPE identifies IP packets based on the customer's classification - it tags their precedence fields to indicate the class they belong to. On each hop along the path, the routers examine the precedence fields of the packets and select the appropriate treatment according to the priority. Thus, the CoS service relies on two mechanisms: (1) Classification, which provides a means to identify the priority of a packet. This translates into a marking scheme defined per CE. All the fields of the IP header can be used for classification. (2) Prioritization at each hop along the path, based on the precedence of the IP packet. This translates into a per-class bandwidth repartition defined per access-link. Prioritization occurs only during congestion. When there is no congestion, the full IP bandwidth is available for the class that needs to transmit, except for the Real Time class. This ensures simple and seamless end-to-end CoS and priority without the need to change tagging policies company wide. Dedicated Internet Access Optionally, DIA service can be added to any or all sites by adding such access to any MPLS deployment on the MEP or to any Layer 2 evwan node. This service can increase performance and reduce latency especially if the remote/off-net site is in an area such as Asia and the service provider s nearest point of presence is in Los Angeles. Rather than the service provider having to backhaul the service to the closest Internet gateway and diminish the quality and performance of the Internet, IPNET- ZONE can keep the Internet traffic local and transport the MPLS or Layer 2 traffic back to the service provider s closest PoP with or without QoS. PAGE 56

8 Transparent Last Mile Access allows carriers to access the MEP via Layer 3 and evwan via Layer 2 and through a number of last-mile access methods including DSL, T1, Metro Ethernet and others speeds ranging from 1 Megabit to 10 Gigabit. All access is provided by, is fully private and secure, and can even be managed down to the CPE. This wide array of access methods allows service providers to select the degree of access on a per-location basis, depending on their requirements. enables this through direct Edge Integration of last-mile access carriers for each the MEP and the evwan. All Last Mile circuits are backhauled to either the closest MPLS NNI location, or for Layer 2 options to the evwan Core via Layer 1/ Layer 2 to ensure QoS and performance. Tunneled circuits such as cable and FiOS are available where MPLS, Layer 1 or Layer 2 circuits are not.

9 Implementation: evwan Layer 2 s method of connecting locations into the Intelligent evwan Core is through the use of point-to-point, Layer 2 private circuits. These circuits are direct, secure connections from a customer premise into the evwan core. They do not travel over any public infrastructure and therefore they inherently have guaranteed QoS and are ideal for VLAN transparent carrier applications. Implementation: MEP Layer 3 MPLS In certain cases, carrier customers choose to utilize existing MPLS network connections in place of a new private Layer 2 circuit. MEP accommodates this through the use of hierarchical VPN. Inter-Autonomous Systems (AS) services, sometimes known as interprovider services, support VPN s that cross AS boundaries. VPN s might need to cross AS boundaries because of a customer deployment that involves geographically separated AS s. The VPN sites can be provided by the same service provider or by different service providers as part of a joint VPN service offering. These inter-as services can be deployed in two different ways, known as inter-as Option A and Option B. The simplest solution to implement is Option A, also known as back-to-back VRF s. This method essentially turns each of the AS Boundary Routers (ASBR) into the Provider Edge (PE) and treats the adjacent service provider s ASBR as the CE. The second method is known as inter- AS Option B or 2547bis Option B. This option uses Border Gateway Protocol (BGP) to signal VPN labels between the ASBR s and the base MPLS tunnels are local to each AS. Stacked tunnels run from end-to-end between PE routers on the different AS s. Summary In today s competitive landscape, telecommunication carriers are faced with the demand for ubiquitous network reach, increased bandwidth, intelligent routing of sensitive, real-time applications and an enterprise client base that will no longer accept the unpredictable nature of IP-based virtual private networks. To remain relevant, carriers must be prepared to support off-net locations that haven t justified building out expensive PoP s, using both Layer 3 and Layer 2 technologies. With s introduction of the MEP and evwan, carriers of all sizes can now take advantage of and gain access to a global off-net network without having to spend money on deploying new PoP s, signing new MSA s, making multiple new commitments, nor taking multiple new NNI s, etc. Inherently within the MEP, carriers can offer access to services that support real-time and mission critical applications, for their demanding enterprise customers. The MEP, while built to access multiple MPLS networks over a single eenni, also offers the ability for carriers to leverage s evwan, a fully VLAN transparent Layer 2 Ethernet service; and all of this is offered over single -provided eenni. DIA, QoS and COS can also be customized to meet the bandwidth, engineering and security requirements for each carrier. s approach thus enables its customers to quickly implement robust, end-to-end MPLS interconnectivity solutions at-scale with minimum up-front investment and the ability to monetize the emerging MPLS interconnect model, thereby increasing profitability and reducing financial and operational risks. s evwan CAP Ethernet over TDM CAP Ethernet Point to Point Point to MultiPoint eenni VLAN2148 VLAN2149 VLAN2260 VLAN3940 Single NNI for multiple services ILEC Metro E VLAN transparency puts you in control Point to Point and Point to Multipoint configurations Many On-Net Partners allowing for nationwide and global layer 2 access PAGE 78
