  1. Carrier Ethernet / Broadband Evolution Dr.Ulrich Schoen Siemens ICN Carrier Products – System Engineering ITU All Star Access Workshop, 2-4 June 2004

  2. ... but, Ethernet must become CarrierGrade! (VMAN, MPLS, OA&M ...) Ethernet is the „natural Language“ of IP ... (cheap, packetizing, statistical gain ...) … the Broadband Networking Trend: Almost all Carrier Services will be IP-based! (www, VPN, VoIP, TV/Video ...)

  3. $ Monthly Rate 100$ 60 $ 28 $ 21 $ 10 $ Broadband Deployments:Bitrate Efficiency vs. Revenue Profitability Access Bitrate Mbit/s 100 Mbit/s 100 Mbit/s 40 Mbit/s 26 Mbit/s 3 Mbit/s DTAG (Germany) APAC Strategy eAccess (Japan) Chunghwa (Taiwan) Source: Broadband World Forum 05/2004 Dr.Semmoto (eAccess) et.al. APAC, especially: (South)Korea, Japan, Taiwan, China ...

  4. Example:KT’s Next Services over Broadband

  5. .... for this Broadband Services Trend to become real, a very cost effective, performant and dedicated Packet Network is key:

  7. Does not require MPLS-aware nodes near to the customer location PE nodes still need to implement one virtual bridge per VPLS instance Additional protection via MPLS Fast Reroute only between PE nodes – additional Ethernet protection mechanisms are necessary between PEs and CEs Good scalability full mesh of tunnel LSPs between PE nodes is still required, but the number of PE nodes is dramatically decreased Services can still be carried over an IP/MPLS core network IP/MPLS Core Network MPLS MPLS MPLS MPLS Provider VLAN VC-LSP Provider VLAN Tunnel-LSP A combination of VLAN access andMPLS-based IP Core is scalable and efficient Metro Ethernet Network Metro Ethernet Network hiD hiD CE VLAN VLAN hiD hiD CE Site A Site B hiD hiD MPLS MPLS Site D Site C PE PE VLAN VLAN Network Architectures CE CE

  8. Carrier Ethernet: Characteristics and Objectives

  9. Ethernet Standardization:Many Standardization bodies involved • IEEE 802 • Provider bridge, Fault management, Link Security, QoS • DSL Forum • Ethernet based Access Networks, QoS • MEF • Services, OAM, UNI/NNI, Traffic Management, Protection, Circuit Emulation • ITU • Services, Equipment, UNI/NNI, Circuit Emulation (SG15) • OAM, QoS, Traffic Management, Protection, VPNs (SG13) • CCSA • China specific Ethernet definitions • IETF • Ethernet over IP/MPLS, L2VPN

  10. NG Broadband networks will be based on Ethernet/VLAN and MPLS A carrier grade NG Broadband network needs An efficient end-to-end management solution Reliable and scalable nodes and network architectures Leading edge access technologies Carrier Ethernet relies on standards that secure investment policy.
