    摘要: In a communications network having a plurality of interconnected nodes adapted to communicate with each other by transmitting packets over links, with more than one path available between source-destination node pairs, a network interface is associated with each node. Each network interface has a plurality of route tables for defining a plurality of routes for transferring packets from the associated node as source node to a destination node. Each network interface further includes a path status table of path status indicators, e.g., bits, for indicating whether each route in the route table is usable or unusable as being associated with a fault. A network manager monitors the network to identify link events, and provides path status indicators to the respective network interfaces. The network manager determines the path status indicator updates with reference to a link level of each link event, and consolidates multiple substantially simultaneous link events.

    摘要: In a communications network having a plurality of nodes adapted to communicate with each other, and more than one path available between most source-destination node-pairs, a network interface is associated with each node. Each network interface has a plurality of route tables for defining a plurality of routes for transferring each packet from a source node to a destination node. Each network interface further includes a path status table of path status indicators, e.g., bits, for indicating whether each route in the route tables is usable or is unusable as being associated with a fault. The network manager monitors the network to identify faults and provides the path status indicators to the respective network interfaces. Failed routes in the network are avoided based on the path status indicators. When a failed route is restored, such that the route is usable again, the path status table indicates that the usable state is restored. A balance of route usage in the network is maintained, without modifying routes or establishing different routes, enabling reliable and high-performance message transfer.
