  12. Ethernet over PDH

  13. What is Ethernet over PDH (EoPDH) ? • PDH (Plesiochronous Digital Hierarchy) • Term to collectively refer to T1/E1 and T3/E3 circuits • EoPDH enables Ethernet and IP services to be delivered over PDH access networks • Two ‘competing’ technologies to deliver EoPDH • MLPPP/BCP over PDH (RFC1990 / RFC3518) • for encapsulation, bonding and bridging • GFP over PDH (G.8040) • GFP (G.7040) for encapsulation, • VCAT (G.7041) and LCAS (G.7042) for bonding • EoPDH Equipment support • MLPPP/BCP supported on essentially all routers and new service edge aggregation devices • GFP supported on new types of devices • Service Bandwidth Options • Up to 12Mbps (8 bonded T1s) • Up to 16Mbps (8 bonded E1s) • Up to 32Mbps (1 E3) • Up to 45Mbps (1 T3)

  14. Why Ethernet over PDH ? • Enables multiple revenue generating services over a single Ethernet UNI • E.g., Internet access, managed VoIP, Ethernet Access to managed IP VPN, E-Line and E-LAN L2 VPNs • Works over existing copper PDH access networks with no speed or distance limitations • Provides Ethernet UNI handoff to subscriber • Utilizes T1s, E1s, T3 or E3 • T1s are the most widely deployed access network technology for businesses data networking in North America • Enables next generation Radio Access Networks from cell sites to interface to existing microwave radio equipment and PDH backhaul circuits • Addresses underserved sub-10Mbps Business Ethernet services market only addressable via copper access networks • $5B cumulative service revenue between 2006-2010* • Less than 14% of U.S. commercial buildings have access to fiber* • Fits within service provider’s existing network infrastructure • Service providers have offered T1 Internet Access for businesses for years • Still a significantly growing business • EoPDH requires no significant network operation or infrastructure changes • * Vertical Systems Group

  33. The Ethernet Advantage • Ethernet provides the bandwidth required to support next generation applications and services • Ethernet Access completes the connection • End to end Ethernet provides the most efficient, lowest cost access method for extending Ethernet Metro networks • Broad set of media and topologies supported by the standards while keeping consistent service attributes • ITU standards – Copper, Fiber • Hybrid Fiber Coax and Wireless • Adherence to standards ensure consistent delivery of Ethernet access services

  34. MEF Certifications Program: Access Technologies • The MEF Certification Program will address access technologies to ensure conformance with Carrier Ethernet attributes • The initial phase will address the conformance to ITU standards in delivering Ethernet services via copper, fiber and EPON access • The initial phase also includes wireless Ethernet mesh access certification testing, based on forthcoming IEEE 802.11T, ensuring total coverage and mobility of Ethernet services • Liaison with Cable Labs looking towards aligning Ethernet over HFC work with MEF specifications

  35. Certification Leads to Interoperability • Lets vendors cooperate to build complementary “end-to-end” solutions • Metro Core, Aggregation and Access Edge offerings • Providers have their own supplier ecosystem in place and aren’t looking for a whole new solution • Interoperability among vendors leads to more favorable market conditions • Interoperability provides a wealth of choices • Lowers the barrier of entry to new markets or applications by reducing the attraction of proprietary architectures
