摘要：【中文】描述了用于检测路径故障并且减少由于这种故障而导致的分组丢失的技术，以用于数据中心或其他环境中。例如，源和/或目的地接入节点可以创建和/或维护关于源设备和目的地设备与核心交换机之间的多个端口或路径的健康和/或连接性的信息。源接入节点可以在源接入节点与目的地接入节点之间的许多路径上喷射分组。源接入节点可以使用关于源接入节点或目的地接入节点与核心交换机之间的路径的连接性的信息以限制在其上喷射分组的路径。源接入节点可以在被标识为健康的源接入节点与目的地接入节点之间的路径上喷射分组，同时避开已经被标识为故障的路径。 【EN】Techniques for detecting path failures and reducing packet loss due to such failures are described for use in data centers or other environments. For example, the source and/or destination access nodes may create and/or maintain information regarding the health and/or connectivity of a plurality of ports or paths between the source and destination devices and the core switch. A source access node may inject packets on many paths between the source access node and a destination access node. The source access node may use information about the connectivity of the path between the source access node or the destination access node and the core switch to limit the path over which the packet is injected. The source access node may inject packets on paths between the source access node and the destination access node that are identified as healthy while avoiding paths that have been identified as failed.
