    1. Making Ethernet a Carrier Ethernet Carrier Ethernet World Forum 2005, Berlin This opening session describes what characterizes Carrier Ethernet according to MEF specifications, and how Carrier Ethernet has been specified to make it the preferred method for delivering differentiated services. The session will provide the basis in understanding for the remainder of the sessions during the day.

    2. Agenda Carrier Ethernet drivers for a converged network Carrier Ethernet attributes Carrier Ethernet Architecture Support for Business, Mobile and Residential Services

    3. Carrier Ethernet Drivers Three main areas of broadband explosion are driving Carrier Ethernet: Business Services – where Gigabit connectivity becomes a must with requirement of data center consolidation, storage and disaster recovery, gigabit connectivity between businesses, and through supply chain. Residential Services – where Triply Play/IPTV becomes broadband driver to deliver >20 Mb to homes with TV, VoD, telephony and Internet services Mobile Services – where wireless 3G packet traffic , in addition to WiMAX and Wi-Fi backhaul, will surpass voice traffic just like in the wireline world. All of these broadband requirement drives a new packet friendly infrastructure, where Carrier Ethernet thrives.Three main areas of broadband explosion are driving Carrier Ethernet: Business Services – where Gigabit connectivity becomes a must with requirement of data center consolidation, storage and disaster recovery, gigabit connectivity between businesses, and through supply chain.

    5. … and by the way … The challenge for service providers is to offer the right bundles of services (promotes customer retention) at the right price. This requires a converged network (to keep costs down) and a flexible/nimble one at that. Ethernet is the obvious answer, but in order to deliver it must be made carrier-gradeThe challenge for service providers is to offer the right bundles of services (promotes customer retention) at the right price. This requires a converged network (to keep costs down) and a flexible/nimble one at that. Ethernet is the obvious answer, but in order to deliver it must be made carrier-grade

    6. The New Network Architecture The combination of explosion of broadband services and evolution of Ethernet itself dictates a new transport network architecture, based on Carrier Ethernet, expanding across metro, nation and globe, with carrier-grade scalability, resiliency and manageability. The new Carrier Ethernet based global infrastructure, delivers all IP based applications, as well as new Ethernet-based broadband services.

    7. What’s Carrier Ethernet For the first time in the industry, the MEF outline the Carrier Ethernet definition, it’s monumentally significant. So, What is Carrier Ethernet? Carrier Ethernet is defined as IEEE 802.3 based Ethernet with five carrier class attributes: Scalability means to scale numbers of services instances and scale bandwidth for aggregation and per service. Protection means to provide 50 ms network-wide restoration capability in the event of link or node failure Hard QoS means to deliver end-to-end guarantee bandwidth, delay or jitter in any services provisioned, p2p or mp2mp TDM Support means ability to carry native TDM traffic over Carrier Ethernet, through perhaps Circuit Emulation Services Service Management means carrier-grade service provision and OAM.For the first time in the industry, the MEF outline the Carrier Ethernet definition, it’s monumentally significant.

    8. Carrier Ethernet Standards The five attributes or aspects of Carrier Ethernet have been standardized by several standards bodies with the MEF at fore of driving formation of the standards. Since its inception 4 years ago, The MEF has ratified 11 standards, aka technical specifications, in defining Carrier Ethernet standards. Orange – ratified standards by the MEF; Light Gray – being worked upon by the MEF; Dark Gray – being worked upon by other standards bodies.The five attributes or aspects of Carrier Ethernet have been standardized by several standards bodies with the MEF at fore of driving formation of the standards.

    9. Supporting Business Services Any-to-any Layer 2 VPN to interconnect multiple locations transparently and effectively (with high and guaranteed bandwidth) Supporting the convergence of data and voice

    10. Supporting Transport for IP Network E-LAN connections among routers Any logical IP topology, multiple EVC’s of a single physical interface It supports all business IP services, from IP VPN to Internet access

    11. Carrier Ethernet for 3G/UMTS Backhaul Guaranteed QoS Flexible SLA portfolios for different users and services Flexible bandwidth growth without network upgrade Efficient network for multimedia applications (P2P, P2MP, MP2MP) Secure connectivity for corporate and consumer users Seamless integration with the wireline transport network – both Ethernet and TDM UMTS – Universal Mobile Telecommunication System SGSN – Serving GPRS Support NodeUMTS – Universal Mobile Telecommunication System SGSN – Serving GPRS Support Node

    12. Supporting Residential Triple Play Services TV Distribution Multicast tree(s) is(are) established with QoS guaranteed; Subscribers (the Set-Top-Box) sends request for a channel; Carrier Ethernet filters, only replicates and forwards the requested channel to the subscribers; Video source protection and network protection are set up automatically upon requirement. VoD Service An E-LAN connection is established between DSLAMs and VoD servers; Subscribers (the Set-Top-Box) sends request to RSM for a movie; RSM finds/informs the best VoD server, acknowledge subscribers of such; The subscriber establishes RTP and RSTP session with VoD and Command server respectively. VoIP Service An E-LAN connection is established between WAN routers to build an IP WAN; An E-LAN connection is established between the DSLAMs and the IP PoP in each metro; Caller contacts the SIP Proxy server in order to find the IP address of the called party; Caller establishes RTP session with the called party through E-LAN connection.TV Distribution Multicast tree(s) is(are) established with QoS guaranteed; Subscribers (the Set-Top-Box) sends request for a channel; Carrier Ethernet filters, only replicates and forwards the requested channel to the subscribers; Video source protection and network protection are set up automatically upon requirement.

Service Provider Benefits Greater Revenue Potential - Granular Bandwidth Multiple Revenue Streams from Single Interface Internet Access (E-Line) Ethernet Virtual Private Line (E-Line) Virtual Private LAN Service (E-LAN) BTV and VoD (Triple Play) VAS Enabled (VoIP, L3VPN, TDM/CES etc.) Lower Capital Costs Lower OPEX Costs Higher Customer Retention
