Problems solved by technology

[0012] Although the existing technology realizes the multicast service, because there is no user management function in the above two protocols, all users who can access the Internet can use the multicast service, which is not convenient for operators to manage and collect fees

Embodiment Construction

[0041] The controllable multicast of the present invention is to realize the control of user access by using relevant protocols on control devices with similar functions such as network switch or digital subscriber line access multiplexer (DSLAM). Such as using the Multicast Control Protocol (referred to as IGMP), 802.1X protocol and so on. This embodiment uses the multicast control protocol as an example to describe the present invention. The networking diagram of the present invention is shown in FIG. 1 .

[0042] In order to solve the problem of user management, a local database is established on the control device, and the user's authority is configured in the database. When receiving a user joining request message, the user's authority is queried from the database and controlled according to the user's authority. For message forwarding, see Figure 3.

[0043] In the multicast service, the program is unique and corresponds to the multicast IP address one by one, and the ...

Abstract

The utility model discloses an implementation method for controllable multicasting service. Through the method, the user sends the request to the access control equipment for entering the multicasting service; the access control equipment delivers the request to the multicasting network side and judges the multicasting competence of the user. If the user is able to receive the multicasting program, the access control equipment will transfer the multicasting data flow from the multicasting network to the user, or such data will not be transferred to the user.

Description

technical field [0001] The invention relates to multicast network technology, in particular to a method for realizing controllable multicast services. Background technique [0002] On the Internet, multimedia services such as streaming media, video conferencing, and video-on-demand are becoming an important part of information transmission. The unicast method of point-to-point transmission cannot adapt to this type of business transmission characteristics, that is, one-point transmission and multi-point reception, because the server must provide each receiver with a copy of the IP message with the same content, and the same content is also repeatedly transmitted on the network packets, occupying a lot of resources. Although IP broadcasting allows a host to send an IP packet to all hosts on the same network, network resources are wasted because not all hosts need these packets. In this case, the multicast service emerges as the times require, and its appearance provides a m...
