    • when both of them fail. In a case where the Cisco SCE8000 platform must be replaced, it is possible to remove the bypass modules from the SCE8000 chassis without disconnecting them from the network and then reinstall them in the new SCE platform, so that traffic links are preserved even in a case of complete failure and replacement of the Cisco SCE8000 platform.

  • Page 28

    OPB-SCE8K-MM supports Multi-Mode optics and should be used with SCE8000 equipped with Multi-Mode optics. The optical bypass module is installed either internally, in slot #4 of the Cisco SCE8000 chassis or in an external mounting panel in the rack. Up to two optical bypass modules can be mounted internally, supporting inline insertion into two links.

  • Page 35: The Cisco Sce8000 Platform

    • The Cisco SCE8000 Platform The Cisco SCE8000 is a solution for dual links with load sharing and asymmetrical routing and support for fail-over between two SCE platforms. The Cisco SCE8000 is built to support wire speed processing of full-duplex 10GBE streams. The Cisco SCE8000 can, therefore, be deployed in a multi-link environment, in several different topologies.

  • Page 36: C H A P T E R 3 Cisco Sce8000 Topology And Topology-related Parameters

    Must the system be designed to guarantee uninterrupted Cisco SCE8000 functionality? If so, there must be a backup Cisco SCE8000 platform (or a backup for each platform in an MGSCP topology) to assume operation in case of failure of the primary device.

  • Page 37: Physical Topologies

    Multi-Gigabit Service Control Platform (MGSCP) Topology, page 3-7 • SCE8000 Interface Numbering The following diagram shows the numbering of the SCE8000 interfaces as indicated in the topology diagrams in this chapter. The interface numbering is explained as follows: The first digit is the slot number (always 3).

  • Page 38: Single Link: Inline Topology

    Typically, the Cisco SCE8000 is connected in a full duplex 10GBE link between two devices (Router, BRAS, etc.). When the Cisco SCE8000 is installed as an inline installation, it physically resides on the data link between the subscribers and the network.

  • Page 39: Single Link: Receive-only Topology

    SPAN-ports destinations. Dual Link: Receive-Only Topology In this topology, one Cisco SCE8000 is connected in receive-only mode to two full duplex, 10 Gig links using optical splitters. If the two links are load-shared, asymmetrical routing might occur, and some of the flows may be split, i.e.

  • Page 40: Dual Cisco Sce8000 Topology (cascade)

    Dual Cisco SCE8000 Topology (Cascade) In this topology, two cascaded Cisco SCE8000s are used. This allows a fail-over solution, where in case of a failure of one Cisco SCE8000 the functionality that the Cisco SCE8000 provides is preserved by the redundant platform.

  • Page 41: Multi-gigabit Service Control Platform (mgscp) Topology

    In addition, it is possible to configure the Cisco SCE8000 to use the external optical bypass device • so that in the event of any failure of the Cisco SCE8000, it will be used to provide link continuity. This ensures 100% link continuity at the expense of providing asymmetric routing functionality.

  • Page 42: Type Of Sce Platform Redundancy

    Redundant Cisco 7600 Series Router Two Cisco 7600 Series routers can be used to provide network redundancy. In this topology, one link on each Cisco SCE8000 platform is connected to each router. Therefore, one SCE platform is required for each link.

  • Page 43: Link Continuity

    The internal bypass mechanism of the Cisco SCE8000 allows traffic to continue to flow, if desired, even if the device itself is not fully functioning. In addition, the Cisco SCE8000 is designed with the ability to control up to two external optical bypass devices (one per link). This is needed because the internal bypass mechanism cannot maintain traffic flow in all cases.

  • Page 44

    Link Continuity Figure 3-9 Subscriber 1 Subscriber 2 If the SCE8000 platform fails, traffic flows through the optical bypass module, bypassing the SCE8000, so that traffic on the link is maintained Figure 3-10 Subscriber 1 Subscriber 2 In cascade configuration, installation of the optical bypass module is required Note This optical bypass module can be added to link without altering the basic characteristics of the topology.

  • Page 45: Topology-related Parameters

    On-failure — This parameter determines whether the system cuts the traffic or bypasses it when the • Cisco SCE8000 either has failed or is booting. Traffic bypass can be achieved either through the external optical bypass device or through the internal bypass mechanism of the SPA interface processor.

  • Page 46: Physically Connected Links Parameter

    Note that these defaults apply only when both devices are started together. However, if the primary Cisco SCE8000 fails and then recovers, it will not revert to active status, but remains in standby status, while the secondary device remains active On-Failure Mode Parameter The on-failure mode parameter configures the action taken by a failed box when a failure is detected.

  • Page 47: Asymmetric Routing Topology

    Cisco SCE8000 Topology and Topology-Related Parameters In a single Cisco SCE8000 topology, the value of this parameter is determined by whether or not the link can be completely cut when the Cisco SCE8000 fails, or whether traffic flow should continue across the link in spite of platform failure.
