Abstract: Aspects of the present disclosure relate to detecting and repairing permanently pauses on a flow controlled fabric. In one aspect, one or more computing devices, such as a switch or a centralized controller, may detect whether a port of a network device receives one or more pause messages. The pause messages may instruct the network device to pause data transmission. Further, the one or more computing devices may determine a period of time during which the port receives the one or more pause messages and identify the port as a permanently paused port based on the determined period of time. The one or more computing devices may then reconfigure the permanently paused port to stop complying with the one or more pause messages.

Abstract: System and methods for efficiently distributing data packets in a multi-path network having a plurality of equal cost paths each having the same number of hops are provided. In one aspect, a system and method includes reordering the entries in the routing table of one or more peer routing devices, such that succeeding equal cost next hop routing devices that are interconnected in a Clos formation to the peer routing devices received unbiased traffic from each of the peer routing devices, thus enabling the succeeding next hop routing devices to distribute data traffic evenly over additional equal cost multiple hops further into the network.
