Abstract

The invention provides a message processing method and device, and the method comprises the steps: receiving a first multicast message sent by a bit forwarding portal router, and enabling the first multicast message to comprise a bit string; performing AND operation on the bit string and a forwarding bit string mask included in each effective target bit index forwarding table item to obtain a plurality of bit string operation results; in a target bit index forwarding table, searching whether a target bit index forwarding table item which matches each bit string operation result and is effective exists or not; if the target bit index forwarding table item exists and is valid, acquiring a neighbor bit forwarding router identifier from the target bit index forwarding table item; and sending the first multicast message to a second bit forwarding router indicated by the neighbor bit forwarding router identifier, so that the second bit forwarding router simultaneously sends the first multicast message to a plurality of in-place bit forwarding egress routers according to the bit string.

Description

Technical field [0001] The present application relates to the field of communication technologies, and more particularly to a packet processing method and apparatus. Background technique [0002] IP multicast, implements real-time, efficient data transfer in IP networks, efficient data transfer, can save a large number of network bandwidth, reduce network load. The IP multicast protocol can be divided into multicast member management protocols running between the host and the router, a multicast routing protocol (for example, PIM, MVPN BGP) running between the router. [0003] Based on Bit Index Copy (English: Bit Indexed Explicit Replication, A referred to as: Bier) is a new multicast forwarding technology architecture. During the forwarding process forward, the bit forwarding the entry router (English: BIT Forwarding Ingress Router, abbreviation: BFIR) In the outer layer package Bier header of multicast, the Bier head includes the bit of the identifier of the group BitString. ...
