Traffic any-ratio load method based on Openflow rule

Abstract

The invention provides a traffic any-ratio load method based on an Openflow rule. The method includes the steps that first, egress ports for traffic load distribution and the allocation ratio of each port are firstly configured, and the minimum number of streams of service traffic needing to be allocated by a load is calculated according to the scale value of the configured egress ports, wherein the service traffic needing to be allocated by the load is divided into streams; second, M fields of a message are selected according to the characteristics of load service, and a group of integer values are selected to respectively represent the mi-digit bit string in the binary 01 string of the ith field, wherein the M fields of the message may change randomly; third, after the field bits selected in the second step are permutated and combined, all the stream classification of the service is listed; fourth, the rules used for stream classification matching content corresponding to the same egress port and recorded in the third step are combined so that the hardware table item can be saved or the software performance can be improved; fifth, the rules recorded by software in the steps are issued to hardware or configured to a virtual router.

Description

technical field [0001] The invention belongs to the field of load mechanisms, and relates to a method for arbitrary load ratio of traffic based on Openflow rules. Background technique [0002] Now in the data transmission and storage system of the network, in order to increase the bandwidth and reliability, the data forwarding traffic needs to be allocated to different transmission paths, such as the aggregation port of the second layer forwarding, the ECMP mechanism of the third layer routing and the select of the Openflow switch Type group table configuration. These methods basically rely on HASH operations on the second layer and layer headers of the message, and distribute them to multiple outgoing ports in equal proportions for forwarding. Although the select type group table in the Openflow standard also has weight configurations, it is still the same. The corresponding relationship between these types of packets and ports is still not very clear, and most of them can...

Problems solved by technology

These methods basically rely on HASH operations on the second layer and layer headers of the message, and distribute them to multiple outgoing ports in equal proportions for forwarding. Although the select type group table in the Openflow standard also has weight configurations, it is still the same. The corresponding relationship between these types of packets and ports is still not very clear, and most of them cannot be applied to non-equivalent paths. It is impossible to distribute traffic with traditional load balancing methods
