Status self-adapted method and device for non RPF interface

Abstract

The invention discloses a state self-adaptive method of a non-PRF interface, applied to the state self-adaptive adjustment of the non-PRF interface generating Assert in PIM-DM group network, which includes that: implementing the state identification on a delivering interface of a state refreshing message based on the state refreshing message received by the non-RPF interface; if the delivering interface is in the state that Assert does not occur, synchronizing the non-RPF interface to the state that Assert does not occur. The invention also discloses a state self-adaptive device of the non-RPF interface and a kind of switching equipment. The method, the device and the equipment in the invention reduce the duplication and the forwarding of the messages in the upstream equipment, prevent the downstream equipment processing the illegal message, thereby enhancing the processing ability of the equipment, increasing the bandwidth usage rate, decreasing the bandwidth waste, and improving thewhole processing ability and the fault recovery ability of multicast domain.

Description

State adaptive method and device for non-RPF interface technical field The present invention relates to the technical field of network communication, in particular to a method and device for state self-adaptation of a non-RPF (ReversePathForwarding, reverse path forwarding) interface, and also to a switching device. Background technique Due to the function of saving network bandwidth and reducing network load, the application of multicast technology is becoming more and more extensive. In most cases, multicast is implemented through the PIM (Protocol Independent Multicast, Protocol Independent Multicast) protocol. Among them, PIM-DM (Protocol Independent Multicast-Dense Mode, Protocol Independent Multicast Dense Mode) networking is especially suitable for occasions with dense users. The & pruning (Flooding & Prune) process realizes the establishment and maintenance of the multicast forwarding tree, especially, the pruning process combined with the ASSERT (assertion) mechan...

Problems solved by technology

However, these methods not only require increased hardware investment and high cost, but also cannot fundamentally guarantee the reachability of message reception.

To fundamentally solve this problem, the interface needs to be able to automatically correct errors when the network goes wrong, but there is no similar technical solution in the prior art
