Business flow dispatching method and device

Abstract

The embodiment of the invention provides a business flow dispatching method and device and belongs to the technical field of communication. The specific realization mode of the method comprises the steps of obtaining a traffic value of each piece of business flow identified as general flow according to set cycle time, and judging each piece of business flow according to an Elephant flow judging condition set by a user; and if the service flow satisfies the judging condition, identifying the service flow as the Elephant flow, and dispatching the Elephant flow according to a set dispatching rule. According to the business flow dispatching method, the Elephant flow can be dispatched to a current optimum exit link timely, the exit bandwidth of a network can be utilized fully, and the transmission efficiency of the business flow can be improved.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular, to a service flow scheduling method and device. Background technique [0002] With the development of various enterprises and data centers, enterprises have established branches in different cities, which are closer to users. Major enterprises will also deploy data centers in different cities. There will be more and more communication requirements between these branches and data centers, and the traffic between them will also be diverse. In the traditional network or SDN network, it is found that a small amount of elephant flow consumes most of the network bandwidth, accounting for only 10% of the number, and the highly interactive mouse flow accounts for more than 90% of the number, but less than 10% of the traffic . [0003] Based on the SDN implemented by OpenFlow, the data forwarding and control layers of the switching device are separated. Every new data f...

In the traditional network or SDN network, it is found that a small amount of elephant flow consumes most of the network bandwidth, accounting for only 10% of the number, and the highly interactive mouse flow accounts for more than 90% of the number, but less than 10% of the traffic

This type of service flow transmission usually occurs between point-to-point terminals, and it is difficult to balance it to multiple egresses by using the traditional ECMP load balancing mechanism in the switching chip
