Abstract

Embodiments of the invention provide a detection method for elephant flow, equipment and a system, relate to the technical field of communication and solve a problem that the elephant flow is detected through upgrading a forwarding chip of a switch and storing a flow table to cause high equipment cost in the existing technology. The specific scheme is as follows: a controller receives an SYN message of data flow sent by at least one switch and records parameter information of the data flow, wherein the parameter information includes receiving time of the SYN message, a serial number, a source IP address, a destination IP address, a source port and a destination port which are carried in the SYN message, and a transmission path of the data flow; if an FIN message of the data flow is not received in a preset time threshold, the controller issues a flow strategy to any switch on the data flow transmission path, receives one data message, records the serial number carried by the receiving time of the data message and computes a first average bitrate; and the controller determines the data flow as the elephant flow according to the first average bitrate. The embodiments of the invention are used for detecting the elephant flow.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a method, device and system for detecting an elephant flow. Background technique [0002] In the data center network, due to the existence of multiple links, multiple elephant flows with heavy traffic may be mapped to the same link, causing the aggregated traffic to exceed the port capacity and causing congestion; multiple leaf switches go to the same leaf switch Multiple elephant flows may also be sent to the same spine switch, resulting in downlink traffic aggregation congestion. In this way, because the elephant flow occupies the bandwidth of a certain link, the mouse flow with small traffic cannot be forwarded, and the elephant flow itself may also cause packet loss due to insufficient link bandwidth. Therefore, the detection and processing of elephant flows is particularly important. [0003] When detecting an elephant flow, the exis...
