Abstract

Embodiments of the present invention provide a method and device for traffic load sharing. The method includes: obtaining the current token values ​​corresponding to the M outgoing interfaces according to the information of the M outgoing interfaces, the current token value is determined by the previous token value, and M is a positive integer; according to the The current token value determines the number of screenings and the screening factor of each of the M outgoing interfaces; according to the screening factor and the screening number, the outgoing interface for data flow forwarding is determined from the M outgoing interfaces. Since the current token value of the outgoing interface is related to traffic, the filtering factor and filtering times are determined according to the current token value. Through the filtering factor and filtering times, the outgoing interface with relatively large current traffic can be shielded, and the current traffic is relatively large. Outbound interfaces that are relatively small or currently have no traffic are selected as the outbound interface for data flow forwarding, so as to achieve traffic load balancing on each outbound interface, reduce the packet loss rate, and improve the reliability of data flow forwarding.

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 (SourceInternetProtocolAddress, source Internet protocol address), DIP (DestinationInternetProtocolAddress, destination Internet protocol address), SMAC (SourceMediaAccessControlAddress, source media access control address) and DMAC (DestinationMediaAccessControlAddress, destination media access control address), etc. Hash factor 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 to be forwarded and t...
