    1. Optimizing Metro Ethernet Tim Hubbard Nortel Networks

    2. RHK Telecom Negotiation Tips Educating the Enterprise Customer “Aggregate spending into one contract to draw more bids” Support for Triple play of Voice, Video, and Data “Include renegotiation clause in the event of a downturn” Dynamic bandwidth provisioning “Assure latest technology will be used” Ethernet-based services in high demand “Include termination clauses for poor service” Carrier-class availability and verifiable SLAs

    3. Metro Service Platform Advanced Traffic Management Bi-directional bandwidth control Hierarchical quality of service High performance hardware implementation Global Scalability VPLS H-VPLS Carrier-class Resiliency

    4. Traffic Management

    5. Differentiated Services Requirements

    6. Traffic Management Illustration

    7. Traffic Management Rate Shaping Gigabit throughput on any port with over-subscription Flexible provisioning of bandwidth per subscriber Bi-Directional Rate shaping Support for ingress and egress rate shaping 3 Color Rate Shaping Committed Information Rate (CIR) for guaranteed traffic Peak Rate (PR) for Burst Services Marking for non-conforming excess traffic Granular and Accurate Rate Shaping with 1 and 2 kbps increments for Ingress and Egress rate limiting; Statistics collection: CIR, PR and Dropped Bytes Reserve or limit bandwidth per application/per subscriber

    8. Traffic Management Quality of Service Quality of Service Implementation: Bandwidth allocation per user / per application Classification “QoS” aware and unaware applications Marking DiffServ – IP QoS, 802.1p – Ethernet QoS Classify, Mark/Re-mark, Schedule Scheduling 8 hardware-based queues per port to support:

    9. Traffic Management

    10. Wire-speed implementation of network processing and control Non-blocking architecture delivering “zero” latency No impact on performance when features are activated: Rate shaping QoS Latency is independent of network load High Performance Traffic Management Supports triple-play: voice, video and data [Jodi] Can we get better product shots? These aren’t very clear.[Jodi] Can we get better product shots? These aren’t very clear.

    11. Scalable Multicast Service Delivery Wire-Speed forwarding of Unicast and Multicast simultaneously Adding multicast will not affect unicast forwarding Supports increasing number of user Every new receiver will not slow forwarding Every port in the network can potentially be a receiver Supports increasing number of video streams Every new transmitter will not slow forwarding Every port in the network can potentially be a transmitter No performance drop for video applications Video Conferencing Video Streaming and distribution High Performance Traffic Management Supports triple-play: voice, video and data

    12. Global Scalability

    13. Global Scalability Layer 2 Multiplexing QinQ and MinM End-to-end Layer 2 subscriber services Provides subscriber scalability and separation of subscriber/provider Ethernet control traffic Traditional Layer 2 VLAN service in access Preservation of customer VLAN tags

    14. Global Scalability Hybrid Ethernet/VPLS Metro

    15. “Carrier-Class” Resiliency

    16. Availability Multi-layer Network Resiliency

    17. Availability Management / Fabric Resiliency

    18. Availability, Solutions for Layer-2 Resiliency IEEE 802.1w/s ? IEEE 802.1D Standard - Rapid spanning tree and Multiple instance spanning tree IEEE 802.3ad Link aggregation often used as 1:1 protection switching Provides the benefit of enabling use of “sparing” or standby link when both interfaces are operating normally Dual homed software based redundant ports; Virtual Router Redundancy Protocol (VRRP): Topology intelligent Ethernet protection; Ethernet Automatic Protection System (EAPS) RFC 3619 Ethernet ring-based protection Multiple domains on a ring Multiple domains on a node VLAN can be member of multiple domains Co-exists with STP

    19. Availability – EAPS v2 Ethernet Automatic Protection Switching
