Abstract

The embodiment of the invention provides a routing method and communication equipment in a data center network. The routing method comprises the following steps of: receiving a flow control signal sent by downstream equipment on a forwarding path, wherein the flow control signal is generated after the downstream equipment detects the congestion of the forwarding path, and the flow control signal is used for informing upstream equipment of the congestion; and according to the flow control signal, suspending selection of the forwarding path during path selection. According to the embodiment, based on the flow control signal returned by the downstream equipment, the selection of the forwarding path of the congestion is suspended, so that other equal-cost paths can be selected and waste of bandwidth resources on the equal-cost paths is avoided.

Description

technical field [0001] Embodiments of the present invention relate to the field of data communication, and more specifically, relate to a method for selecting a route and a communication device in a data center network. Background technique [0002] The fat tree architecture is an important deployment scheme of the data center (Data Center, DC) network, and its characteristic is that each access layer switch and each aggregation layer (or as the core layer) switch are connected to each other . Therefore, in order to communicate between any two servers (Server), there may be multiple equal cost paths (Equal Cost Multi Path, ECMP) for selection. [0003] At present, for the route selection of the equal-cost path, the hash (Hash) operation is generally performed through the value of the fixed message characteristic area, such as summation by byte, bitwise AND, and the like. Then select the corresponding path according to the hash result (1 byte), for example, divide the hash ...
