METHOD FOR SELECTING ROUTE IN SCENARIO OF MULTICAST LOAD, AND ROUTER

摘要

A method for selecting a route in the scenario of a multicast load, and a router, which relate to the technical field of communications, and solve the problem of reduction of the system performance caused by congestion or loss of multicast data which is generated because an upstream link shares multicast data of a plurality of routers connected thereto if the upstream link selected by a current router is connected to the plurality of routers when a unicast routing manner is adopted to acquire the upstream link from a receiving end to a multicast source. The method can specifically comprise: a first router acquiring the multicast processing capability of a second router and the multicast processing capability of a third router; and determining one of the second router and the third router, which has the optimal multicast processing capability, to be the optimal upstream router in a downlink direction, the downlink direction being the direction from the multicast source to the first router. The method can be applied to the route selection in the scenario of a multicast load.
