    1、 TECHNICAL REPORT ATIS-0100033 MULTI-LAYER COORDINATION IN ALL-IP NETWORKS ATIS is the leading technical planning and standards development organization committed to the rapid development of global, market-driven standards for the information, entertainment and communications industry. More than 200

Dual-plane is used in softswitch network for higher reliability. In the event a plane fails, the traffic on the plane can failover to the other plane. Priority

    7、Priority: This failure will have high priority. A fiber cut could potentially result in loss of service to a large number of customers. Action/Follow-UpAction & Follow-Up: (i) Immediately fix the fiber cut by switching traffic to the protection fiber. Document detailed report of the incident. ATIS-0

    10、Transmission Protocol Figure 5 - An Example of Alarm-Flow following a cable-cut in a multi-layer network (ii) The alarms will escalate in time through the different layers of the network as shown in Figure 5, if the problem remains unsolved. To ensure coordination amongst the different layers in All

    11、-IP networks the hold-off timers shall be synchronized. Otherwise, in the event of a failure, this lack of coordination between the layers can lead to race conditions. Different network layers will resort to simultaneous restoration activity that lead to route flapping and network instability and other undesired behavior. Furthermore, prevent future incidents by adopting suitable best practices Nrsc-1993, Nrsc-1996, and Nrsc-1997 and adopting steps to prevent their recurrence in Fcc-Nrc, Nrsc-1996, and Nrsc-1997.
