    What’s Carrier Ethernet ?

    Quelle:

    Scalability • Services and

    Bandwidth • 100,000’s of EVC’s • From Mbps to

    x10Gbps

    Protection • 50ms Protection • End to End Path Protection • Aggregated Line & Node Protection

    Hard QoS • Guaranteed end to end SLA • End to End CIR and EIR • Business, Mobile, Residential

    TDM Support • Seamless integration of TDM • Circuit Emulation Services • Support existing voice applications

    Service Management • Fast service creation • Carrier class OAM capabilities • Customer Network Management (CNM)

    Policy-Based QoS Traffic Grouping Classification + QoS Profile => Policy • Classifications: L1-L4 information, WINS username (using EEM and DLCS), Observe and/or

    overwrite 802.1p and IPDiffServ packet markings. • QoS Profile: Determines Bandwidth Management (e.g. Min. Bandwidth %; Max Bandwidth

    %; priority). Option for Random Early Detection. • Layer Independent QoS: Use of Layer 3 & 4, IP DiffServ info without routing;

    ExtremeWare XOS, Tested by Tolly Group

    Key Findings of Tolly Group: Modularity has benefits: • Extensible OS • Higher network availability • Dynamically add functionality

    Process recovery: • Higher network availability • No single process can take down the system

    XOS ACL’s: • Wirespeed ACL forwarding • Dynamic ACL editing • Precise wirespeed “accounting” on matching ACL

    Virtual Domains: • Ability to collapse multiple L3 switches on one device • Flexibility to support overlapping IP addresses

    Pain Point: Ethernet Provisioning Complexity

    SPs needs multi-vendor, multi-technology provisioning of:

    E-Line services (Point to Point) Private line, and Virtual private line

    E-LAN services (Multipt to Multipt) Private LAN, and Virtual private LAN

    Advanced Traffic Management Engine

    Bi-directional (ingress and egress) rate limiting • On egress, “phantom” scheduling is supported to distribute unused

    bandwidth to other customers

    3-tiered hierarchical rate limiting 1. Per application (up to 8 apps per customer) 2. Per customer (up to 4K per 10Gig link / 32K customer in total) 3. Per physical port (up to 160 = 2 * 80-port)

    Packet Classification • Any data field can be used to classify the packet (in 4GNSS

    programmable packet processor = Cartman)
