Method for processing multicast message, line card and communication device

Abstract

The invention discloses a method for processing multicast messages, a line card and a communication device. The method includes: the source line card sorts the multicast messages received by itself within a first set time period according to the sequence of receiving time Store in each memory buffer of oneself in turn, determine the destination line card of each multicast message; Pack the address information of the memory buffer where the multicast message corresponding to each determined destination line card is located, respectively, into After sending an address message to the corresponding destination line card. Correspondingly, the destination line card receives the address packet sent by the source line card, unpacks the address packet to obtain the address information in the unpacked address packet, and sends an acquisition packet request carrying the address information to the source line card ; Receive the multicast packet returned by the source line card, and forward the multicast packet. The present invention reduces the CPU burden of the source line card when performing multicast message transmission processing, improves the CPU utilization rate of the destination line card, and further improves the performance of the whole device.

Description

technical field [0001] The present invention relates to the technical field of PCIE (Peripheral Component Interconnect Express, Enhanced External Component Interconnection Standard) bus technology in the field of communication technology, in particular to a method for processing multicast messages, a line card and a communication device. Background technique [0002] The PCIE bus is a third-generation I / O high-performance bus used to interconnect line cards in communication devices. It is developed based on the PCI (Peripheral Component Interconnect, external component interconnection standard) bus. It adopts a point-to-point serial connection , Each line card has its own independent data connection, and the concurrent data transmission between each line card does not affect each other, thus ensuring the exclusivity of the data transmission channel, avoiding the interference of other line cards, and improving the data transmission rate. [0003] In a communication device usi...
