Problems solved by technology

so, in figure 2 , although there are 4 equal-cost routes from device A to the Internet, but based on the hardware capability limitation of device A, device A can only choose 2 of them to forward traffic to the Internet, while the other 2 equal-cost routes only for backup
This leads to the underutilization of equal-cost routes, greatly reducing the utilization of equal-cost routes

Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] In the present invention, in the scenario where there are N equivalent routes from device A to the destination, but device A only supports M equivalent routes, in order to improve the utilization rate of equivalent routes, that is, to make full use of the remaining N-M( N minus M) equal-cost routes, at least one device can be added in the network, wherein the device is added according to the following principle: the sum of the equal-cost routes to the destination supported by all the added devices is the remaining N-M equal-cost routes , and then select the route supported by the device from the remaining N-M equal-cost routes according to the increased hardware capability of each device. for example, figure 2 In , there are four equal-co...

Abstract

The invention provides a flow transfer method and a piece of equipment. The method is applied to a piece of member equipment which is used for forming a stack system. The sum of the equivalent routing number of the member equipment of the stack system reaching the destination is equal to the number of the equivalent routing of the stack system reaching the destination. The method comprises the following steps: receiving the flow to be transmitted to the destination; determining that the equivalent routings which are related to the destination address of the destination in the transfer table forms of the equipment have at least one effectively routing, and transferring the flow of the effective routing in the transfer table forms to the destination; if equivalent routings which are related to the destination address of the destination in the transfer table forms of the equipment break down, according to the routing information that all the member equipments of the stack system reach the destination, adopting at least one of the other member equipments which is replaced with the equipment to transfer the flow to modify the equivalent routing related to the destination address of the destination in the transfer table forms as the stack link of the equipment and other member equipments; and transferring the flow to the other member equipments according to the modified stack link after being modified in the transfer table forms.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a traffic forwarding method and equipment. Background technique [0002] In a network environment where the same destination address is reached through multiple different links, if traditional routing technology is used, the data packet sent to the destination address can only use one of the links, and the other links are in backup or invalid state. The Equal-Cost Multipath Routing (ECMP: Equal-Cost Multipath Routing) protocol can allow multiple links to be used simultaneously in the above-mentioned network environment, which not only increases the transmission bandwidth, but also realizes backup of failed links without delay and packet loss. data transmission. like figure 1 As shown in the figure, for user traffic accessing the Internet, there are three equal-cost routes to the Internet on the L3 switch. Based on this, the traffic accessing the Internet can be load-balance...
