Embodiment Construction

[0020] For the convenience of reading and understanding, the English abbreviations are explained as follows:

[0021] AAA Authentication, Authorization and Accounting

[0022] IGMP Internet Group Management Protocol

[0023] IGMP JOIN The request packet for applying to join a network group in the Internet network group management protocol

[0024] PPP point-to-point communication protocol

[0025] PPPoE Transport PPP over Ethernet

[0026] figure 1 What is shown is a typical network diagram of the application of the present invention. The authentication method for the multicast service described in the present invention is mainly applied in the broadband access network, and can also be applied in any data network with user management function on the node.

[0027] The current broadband access network is mainly composed of the following parts: central office equipment and user end equipment. The central office equipment and the user end equipment are connected by optical ...

Abstract

The invented method for authenticating the multicast request includes following steps: (1) the authentication for logging the user on. (2) The network device records the user's related information, combining with the operation attributes (whether the multicast is opened) to generate one recorder. (3) The user obtains the genetic networked service through network (4). The user send out the request package of applying for joining a multicast group. (5) With the request package being received, the network device picks up the user's relevant information. (6) Base on the user's information, the network device searches the recorders. If the user is a legal user of the multicast group, the authentication is passed. Otherwise, the user is refused admittance.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method for authenticating multicast services in a broadband access system. The invention provides a method for identifying the legal identity of users as a precondition for charging value-added services in the broadband network. Background technique [0002] At present, in the field of data communication, broadband technology has been more and more widely used. When multiple users apply for a service (such as video and audio services) on the Internet at the same time, the corresponding server must send datagrams with the same content to each user. At this time, a multicast address can be used to identify all For users, the server only needs to send a datagram to this virtual multicast address, and the nodes on the network will automatically send it to the corresponding multicast user, instead of sending the same datagram to each user separately. This process is called multica...
