Abstract

The embodiment of the invention provides a method for selecting an outlet interface. The method comprises the following steps: obtaining the multicast rate; comparing the bandwidth of each member interface in a trunk interface with the multicast rate to obtain a first set, wherein the first set comprises all the member interfaces with bandwidth more than or equal to the multicast rate in the trunk interface and the trunk interface is the multicast outlet interface and comprises a plurality of member interfaces; and determining the multicast outlet interface according to the first set. Besides, the embodiment of the invention also provides corresponding equipment. By adopting the technical scheme provided by the embodiment of the invention, the technical problem of loss of the multicast flow can be solved.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a method and device for selecting an outgoing interface. Background technique [0002] Convergence (Trunk) port can provide point-to-point links. Specifically, bandwidth between switches and network nodes is increased by bundling multiple physical interfaces into a single logical link. When transmitting unicast traffic, the bandwidth of multiple physical interfaces can be combined to provide an interface with a bandwidth higher than that of any one of the multiple physical interfaces. [0003] When the convergence interface is used as the outbound interface of multicast, each member interface in the convergence interface may become a physical interface for forwarding multicast traffic. In the above technical solution, multicast traffic may be lost. Contents of the invention [0004] The embodiment of the present invention provides a method and equipment...
