    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.

    摘要翻译： 在具有多个互连节点的通信网络中，网络接口与每个节点相关联，所述多个互连节点适于通过链路发送分组而相互通信，具有多个可用的源 - 目的地节点对之间的路径。 每个网络接口具有多个路由表，用于定义用于将分组从作为源节点的关联节点传送到目的地节点的多个路由。 每个网络接口还包括路径状态指示符（例如，位）的路径状态表，用于指示路由表中的每个路由是否可用或与故障相关联。 网络管理器监视网络以识别链路事件，并向各个网络接口提供路径状态指示符。 网络管理器参考每个链路事件的链路级别来确定路径状态指示符更新，并且整合多个基本上同时的链路事件。

    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.

    摘要翻译： 在具有适于彼此通信的多个节点以及多个源 - 目的地节点对之间可用的多于一个路径的通信网络中，网络接口与每个节点相关联。 每个网络接口具有多个路由表，用于定义用于将每个分组从源节点传送到目的地节点的多个路由。 每个网络接口还包括路径状态指示符（例如位）的路径状态表，用于指示路由表中的每个路由是否可用或不能用于与故障相关联。 网络管理器监视网络以识别故障，并将路径状态指示器提供给各个网络接口。 基于路径状态指示灯可以避免网络中的路由失败。 当路由恢复失败时，路由可以再次使用，路径状态表指示恢复可用状态。 保持网络中路由使用的平衡，不修改路由或建立不同的路由，实现可靠，高性能的消息传递。
