A method and device for implementing equal-cost multi-path in ip routing

Abstract

The invention discloses a method for realizing equal cost multipath of IP route and a device; wherein the device comprises an ECMP group generation module, a route ECMP configuration module, a route ECMP searching module; the corresponding method has the following steps: the ECMP group generation module configures the number of members of the ECMP group and determines the number of groups of the ECMP group; the route ECMP configuration module averagely writes all next hop outlets of a load sharing module into the ECMP groups and sets corresponding ECMP groups for IP address network segments which need ECMP routing; when ECMP routing is carried out on data, the route ECMP searching module carries out Hash calculation on target IP addresses of the data, and then uses the Hash calculation values to carry out modulo on the number of members of the ECMP groups and adds base addresses of the ECMP groups corresponding to the data to obtain the next hop outlet, and finally transfers the data from the next hop outlet. With the method and the device of the invention adopted, data can be conveniently, flexibly and uniformly routed to opposite terminal equipment.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and device for realizing IP routing equivalent multipath. Background technique [0002] With the rapid development of the Internet, IP networks have gradually become an indispensable tool in people's daily work and life, and IP network devices have increasingly become mainstream Internet core data exchange devices. [0003] In an IP network, the most critical technology is routing, which is the path of IP data transmission and the lifeline of IP. With the large number of applications of IP networks this year, the data transmitted by IP network devices is also increasing. Due to the limitation of the transmission capacity of the physical interface, a large amount of data transmission on two IP network devices requires multiple physical interfaces (such as figure 1 shown). In order to allow IP data to be transmitted on these physical interfaces, complex ro...

Problems solved by technology

Due to the complexity of data in the network, the data traffic on these physical interfaces is bound to be uneven, resulting in excessive traffic on some physical interfaces and waste of transmission bandwidth on some physical interfaces.
