Abstract
According to at least one particular embodiment of the present invention, in an ASM-based RP, when the RP receives a multicast transmission request from a multicast source, it processes said multicast transmission request of the multicast source according to the multicast transmission request and remaining resources available for multicast forwarding in the RP. When using the methods and apparatuses provided in the present invention, by means of reasonable controls on the multicast transmission request conducted by the RP according to its resource situation, the hardware processing loads and the port traffic load of RP can be effectively maintained within an appropriate range, thereby avoiding resource exhaustion, and the disadvantageous impact of new multicast services on the existing services can be also avoided.
