Abstract

The present specification provides a method for realizing ECMP traffic load balancing and electronic equipment, the method being applied to a forwarding device, the method comprising: monitoring a bandwidth occupancy rate of each link allocated to a plurality of data streams with the same target address, the forwarding device allocates the links to the plurality of data streams with the same target address based on a Hash algorithm; under the condition that the bandwidth occupancy rates of all the links are unbalanced, the types of data streams in the links with the bandwidth occupancy rates exceeding a threshold value are identified, and the types of the data streams comprise elephant streams; the identified elephant flow is switched to a light-load link according to an ACL rule, the ACL rule is configured according to quintuple information of the identified elephant flow, and the light-load link is a link with the bandwidth occupancy rate not exceeding the threshold value. According to the method, the problem of link traffic imbalance can be found in time, and traffic load balancing of each link is realized by switching the elephant flow on the overload link to other light-load links.

Description

technical field [0001] This specification relates to the field of communication technologies, and in particular to a method and electronic equipment for implementing ECMP traffic load balancing. Background technique [0002] The multi-path load balancing problem existing in the network using TCP / IP as the transmission protocol is usually solved by using ECMP (Equal Cost Multi-path, Equal Cost Multi-path) routing technology. ECMP generally uses the HASH algorithm to determine the transmission paths of different data flows, but this method only considers the balance of the number of data flows on each path when determining the transmission path, and does not consider the size of each data flow. The problem of (link) traffic imbalance. [0003] The DLB (Dynamic load balance, dynamic link load) technology solves the problem of unbalanced traffic in ECMP by transmitting packets in the elephant flow in different paths. However, this method is complex to implement and requires ch...
