Problems solved by technology

[0010] The technical problem to be solved by the present invention is: when the prior art distinguishes multiple multicast terminals under the same access port according to the MAC address, it is not applicable to access methods such as PPPOA or IPOA, and the recording of the MAC address takes up a large space Insufficient, provide a method for multicast management of multiple terminals under the same access port, meet the needs of different access methods when distinguishing multicast terminals, and reduce the space occupied by user records in the access device

Embodiment Construction

[0025] Below according to accompanying drawing and embodiment the present invention will be described in further detail:

[0026] The present invention utilizes the existing multicast IGMP message format to extend the IGMP protocol. In the process of constructing IGMP report messages and leaving messages, different multicast terminals under the same physical port will use the numbers of different terminals (1, 2... ) to fill in unused fields. The terminal number can be set by software on the terminal that constructs the IGMP message. Since the unused field has 8 bits, a terminal can be represented by one bit, and 8 multicast terminals can be supported under one physical port. In the access device, for the received IGMP report message and leave message, analyze their unused fields to ensure that the access device can distinguish the terminals that go online and offline by the numbers therein. The terminal number can be set by software on the terminal that can construct the IGM...

Abstract

A multicasting managing method to multiple terminal of same incoming end port includes: configuring each multicasting terminal number of same incoming end port; when different multicasting terminal in constructing internet multicasting management protocol message or leaving message, filling terminal number in unused field in internet multicasting management protocol message; router side equipment through analyzing received said unused field in internet multicasting management protocol message and leaving message, distinguish each multicasting terminal in same incoming end port. The present invention can reduce user record occupied space in access equipment, having high identifying user efficiency.

Description

technical field [0001] The invention relates to the technical field of multicast services, in particular to a method for multicast management of multiple terminals under the same access port. Background technique [0002] With the development of broadband services, users are no longer satisfied with basic web page browsing and file downloading, and services such as video, distance education, stock information, and video conferencing are growing rapidly. Therefore, the Internet-based multicast service has become a major application to promote the sustained and rapid development of broadband services. [0003] With the expansion of multicast services, especially video services, many families have started to use multicast video services. Due to the improvement of living standards, many families have multiple media receiving devices (such as TVs, computers), and in actual operation, a family generally puts one access port. Multiple multicast terminals under the same physical a...
