A packet transport network recovery system based on failure pattern under examination of transmission quality is proposed. Network failures are segmented into one of the three patterns: single failure of a node, failures of multiple nodes, and failures of multiple network areas. The single failure is recovered by a protection scheme. For failures of multiple nodes or multiple areas, recovery is performed by a node-based multiple-backup operation plane scheme or by an area-based multiple-back operation plane scheme, respectively. A unique recovery ID is assigned to each failure pattern and backup paths with the recovery ID are stored in each node. When network failures occur, the network management server determines the type of failure and sends the appropriate recovery ID to the nodes. Then recovery paths are configured. Our proposed system took about 0.5[Formula: see text]s to configure 1000 backup paths after failures were detected, compared to about 4[Formula: see text]s by a conventional scheme. For the examination of data transmission quality, multiple paths that do not share the same link are grouped and configured concurrently. The number of groups is regarded as the performance of the configuration. The performance of the proposed system is about three times faster than a configuration without grouping.
