Problems solved by technology

[0005] In order to solve the problem of high processing pressure when the multicast traffic of the same multicast source is carried by a single routing device, this disclosure proposes a multicast traffic processing method, device and routing device to realize the multicast traffic of the same multicast source. Broadcast traffic is carried by multiple routing devices

Embodiment Construction

[0025] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0026] The terminology used in the present disclosure is for the purpose of describing particular embodiments only, and is not intended to limit the present disclosure. As used in this disclosure and the appended claims, the singular forms "a", "the", and "the" are intended to include the plural forms as well, unless the context clearly dictates otherwise. It should also be understood...

Abstract

The present disclosure provides a multicast traffic processing method, device and routing device. The routing device receives the first assertion message sent by other routing devices in the same network segment, and the message includes the priority of the unicast route to the multicast source. , the metric value to the multicast source and the identifier used to indicate whether the routing device has carried the multicast traffic of the multicast source; determine the second routing device from the network segment, and the second routing device is from the routing device with the highest priority determining the routing device with the smallest metric value; determining a third routing device from the second routing device, where the third routing device is a routing device that does not bear the multicast traffic of the multicast source determined based on the identifier corresponding to the second routing device; The first routing device used to bear the current multicast traffic is determined in the third routing device. In the present disclosure, multiple routing devices jointly bear the multicast traffic of the same multicast source, so the processing pressure of a single device can be reduced.

Description

technical field [0001] The present disclosure relates to the technical field of network communication, and in particular to a multicast traffic processing method, device and routing device. Background technique [0002] PIM (Protocol Independent Multicast, protocol-independent multicast) uses static routing or a unicast routing table generated by any unicast routing protocol to provide routing for IP (Internet Protocol, Internet Protocol) multicast. Multicast routing is independent of the unicast routing protocol used. [0003] The PIM realizes the forwarding of the multicast message by means of the RPF (Reverse Path Forwarding, reverse path forwarding) mechanism. When a multicast packet arrives at the local device, it first performs an RPF check: if the RPF check passes, a corresponding multicast routing table entry is created to forward the multicast packet; if the RPF check fails, the packet is discarded . [0004] When there are multiple routing devices supporting PIM...
