Abstract

The embodiment of the invention provides a method and a device for sharing traffic load. The method comprises the following steps of: obtaining corresponding current token values of M output interfaces according to information of the M output interfaces, wherein the current token values are determined according to the previous token values, and the M is a positive integer; determining screening times and screening factors of each of the M output interfaces according to the current token values; and determining the output interfaces for forwarding data streams according to the screening factors and the screening times. The current token values of the output interfaces are relative to traffic, so that the screening factors and the screening times are determined according to the current token values, the output interfaces with relatively high current traffic can be shielded according to the screening factors and the screening times, the output interfaces which bear relatively low traffic or bear no traffic are selected as the output interfaces for forwarding data streams, and thus, the traffic load on each output interface is balanced, the packet loss rate is reduced, and the reliability of data stream forwarding is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and more specifically, to a method and device for traffic load sharing. Background technique [0002] Route load balancing is an effective means to improve network reliability and stability. Common load sharing methods include Hash algorithm, packet-by-packet load sharing, and MinMiss algorithm. [0003] Among them, the Hash algorithm analyzes SIP (Source Internet Protocol Address, source Internet Protocol address), DIP (Destination Internet Protocol Address, destination Internet Protocol address), SMAC (Source Media Access Control Address, source media access control address) and DMAC ( Destination Media Access Control Address, destination media access control address) and other Hash factors to select routes. Due to the hash limitation of the Hash factor, the traffic burden will be unbalanced. For example, if there are 4 outbound interfaces and 10 data flows t...
