Embodiment Construction

[0032] Below according to accompanying drawing and embodiment the present invention will be described in further detail:

[0033] The invention separates a part of the IGMP processing function from the control module of the access device, adds an acceleration module in the access device, and utilizes the acceleration module to assist in completing the processing of the IGMP message. The acceleration module receives the user's IGMP message, completes the preliminary processing of the user information (such as legality check, user authentication, etc.), and then hands the user information to the control module for processing (such as the control module according to the user information reported by the acceleration module, Modify the user status information, refresh and maintain the multicast forwarding table).

[0034] The acceleration module can be realized by ASIC (application-specific integrated circuit), FPGA (field programmable gate array), NP (network processor) and other ...

Abstract

A method for realizing channel switching in video multicasting service includes setting an acceleration module in broadband access equipment to process IGMP message for channel switching by auxiliary module of said acceleration module, said method contains the data transmitting module sending the user received IGMP message to acceleration module to be primary processed, then the processed user information sent to control module for further processing to update for realize channel switching. Said primary process includes validity check and user authorization. Said invention greatly raises the ability of processing IGMP message and insures channel switching speed in providing video multicasting service.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for realizing channel switching in video multicast service. Background technique [0002] Multicast is a network technology that allows one or more senders (multicast sources) to send the same data packet to multiple receivers at the same time. It is a network technology that can multiply services without increasing the load of the backbone network. It is an effective solution for the number of users, and therefore becomes the first choice for current high-traffic video services. Using IP multicast packets to distribute video program streams to users is video multicast. For operators, the video multicast service is becoming more and more important, whether they want to become a real full-service operator, seize the high-yield cable TV market, or just want to develop attractive broadband value-added services to Attracting more users to use the broadband network a...
