Abstract

The invention provides a flow forwarding method and a flow forwarding device. The method is applied to an Openflow Controller in an OpenFlow network and comprises the following steps: A, determining exchange equipment for simultaneously bearing N equivalent paths in the OpenFlow network; B, notifying the exchange equipment of creating a flow distribution group, adding an output port corresponding to each path in the N equivalent paths on the exchange equipment into the flow distribution group; and C, distributing a first OpenFlow meter corresponding to the flow distribution group to the exchange equipment, wherein the first OpenFlow meter contains destinations of the N equivalent paths and is used for the flow distribution group as the output port, so that when the exchange equipment forwards the flow to the destinations, the flow distribution group in the first OpenFlow meter is used as the output port to forward the flow.

Description

technical field

[0001] The invention relates to network communication technology, in particular to a traffic forwarding method and device. Background technique

[0002] Port aggregation is to bind two or more physical ports on the switching device together to form an aggregation port through configuration software settings, and each physical port that forms the aggregation port is called a member port. Among them, the aggregation port combines the bandwidth of each member port to provide a high bandwidth several times that of each member port.

[0003] see figure 1 , figure 1 It is a schematic diagram of a port on a switching device. exist figure 1 In this example, in order to increase the network bandwidth between the local network node and the peer end, the physical ports P1, P2, and P3 on the local switching device are bundled together to form an aggregation port 1. so, such as figure 1 As shown, the switching device has four ports at the forwarding level, namely: P...
