Abstract:
A "network-disaster recovery system" using area-based network management is proposed. In this system, a whole network is separated into multiple areas. A network-management server calculates recovery paths for every possible network-area failure and distributes them with a recovery identifier (ID) for each area-failure pattern before starting network operations. Network nodes receive and store the recovery IDs and recovery configurations. The network-management server determines after detecting the network-area failures and distributes the recovery ID to related network nodes. The network nodes that received the recovery ID start data transmission according to the path configurations specified by the recovery ID. After these procedures are completed, the network-area failures are swiftly recovered. A prototype system composed of a network-management server and 96 simulated packet-transport nodes was configured and evaluated. According to the evaluation results, the network-management server could transmit the recovery ID to the related network nodes within 100 milliseconds after it detected network-area failures. That is to say, the network could immediately start to recover from the network-area failures. On the other hand, the calculation time for 500 Pseudo Wires (PWs) is about 344 milliseconds, which is longer than the time taken to distribute the recovery ID (i.e., 100 milliseconds). In other words, if there are over 500 PWs, the proposed system can recover more swiftly than a conventional system (which re-calculates recovery PWs after detecting the network-area failures) under the same evaluation conditions used for the proposed system.
