Embodiment Construction

[0027] Various preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] The multicast fast joining method for broadband access equipment of the present invention, its core idea is to listen to the IGMP REPORT message on the user board, and analyze the message on the user board, if the analysis result shows that the message applies If the multicast group allows fast joining, then directly add the user to the multicast group maintained on the user board, and continue to send the REPORT protocol message to the main control board, otherwise, do other processing. Here, the service layer on the side of the main control board ensures that as long as users who have the right to join the multicast group must be able to join quickly.

[0029] The realization flowchart of the inventive method is as figure 1 As shown, what needs to be explained is:

[0030] 1) the information of the obtained IGMP REPORT pack...

Abstract

The invention relates to a method for accessing multicast in wide band access device. Wherein, it comprises that the user plate detects the internet group manage protocol report; the user plate analyzes the report; the analyzed result is the multicast group requested by report that allows the user access, adding the user into the multicast group of user plate, and transmitting the report to the main control plate; the service layer of main control plate confirms the access with multicast priority. The invention directly analyzes IGMP REPORT at user plate, to balance load and reduce access time.

Description

technical field [0001] The invention relates to an Ethernet multicast method in the field of computer network communication, in particular to a method for processing multicast protocol messages on a user board in a broadband access device. Background technique [0002] In most of the current large and medium-sized access devices, the basic multicast access method is to use the user board in the device to listen to the IGMP REPORT (Internet Group Management Protocol Report) message, and transparently transmit it to the main control board to maintain the group. playlist. Its main working method is: the user board detects the protocol type of the IP header in the Ethernet packet, extracts the IGMP REPORT message, and transparently transmits it to the main control board; the main control board uses the REPORT protocol message sent by the user board to perform a series of judgment checks : (1) first check the validity of the REPORT protocol message, and if it is legal, then proc...
