Flow distribution method and apparatus

Abstract

The invention discloses a flow distribution method and apparatus. The apparatus comprises a mode selection module used for selecting one preset flow distribution mode which has an output port selection function, a flow adjustment function and a session granularity selection function; a parameter input module used for inputting configuration parameters corresponding to the flow distribution function; a port data obtaining module used for obtaining flow data of an input port and an output port in real time and predicting future flow data of the input port according to the obtained flow data; a function calculation module used for, according to the configuration parameters, the flow data of the input port and the output port and the predicted future flow data of the input port, executing the output port selection module, the flow adjustment function and the session granularity selection function; and a distribution module used for distributing flow from the input port to the output port according to a function execution result. According to the scheme disclosed by the invention, the utilization rate of port bandwidth is improved and network experience of users is improved.

Description

technical field [0001] The present invention relates to the field of network communication, in particular, to a flow distribution method and device. Background technique [0002] In the network of the data center or computer room, between network domains such as the egress of the external network, a traffic distribution device is generally set up to undertake the function of egress / entry traffic distribution. Generally speaking, due to reliability, content buffering, cost, and the difference and asymmetry of the size and type of uplink and downlink traffic, there may be multiple traffic egresses, such as operator 1 egress, operator 2 egress, and operator 3 egress. Due to the different rental fees, bandwidth size, uplink and downlink traffic size, reliability, and content caching of these outlets, traffic distribution equipment is often required to distribute different traffic to different outlets in a targeted manner. The traditional solution is to use policy routing and ot...

AI Technical Summary

Problems solved by technology

The traditional solution is to use policy routing and other technologies to select traffic egress ports. However, due to the relatively fixed mode of traditional measurement routing and other technical solutions, the granularity of traffic selection is relatively large, and it is impossible to dynamically select traffic with different granularities according to changes in demand and situation. The distribution to the best outlet makes the device unable to flexibly and efficiently complete the function of traffic distribution. There are similar problems in the return traffic distribution method, so I won’t repeat them here.
