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

Example:KT’s Next Services over Broadband
.... for this Broadband Services Trend to become real,
a very cost effective, performant
and dedicated Packet Network is key:

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
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

Carrier Ethernet: Characteristics and Objectives
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.
