Embodiment Construction

[0023] Below in conjunction with accompanying drawing and embodiment, content of the present invention and the background technology on which it is based are described in detail:

[0024] (1) IGMP protocol

[0025] In the existing multicast model, any host is allowed to join the multicast group without verification, and there is no access control for the multicast participants. Any host can send a join request message to an adjacent multicast router, and the router sends a join request to the upper multicast tree. Once the join request is successful, the multicast tree will be extended to the subnet, and the host that sent the join request can receive multicast data.

[0026] Usually, the IP host uses Internet Group Management Protocol (Internet Group Manage Protocol, IGMP) to report the multicast member information to the multicast router. The IGMP message is encapsulated in an IP packet whose TTL value (life value, Time to Live) is 1. For example, the format of an IGMPv2 ...

Abstract

A strategy control based multicast access control method for multicast network, which contains leading strategy control system, the multicast access user sending access request and own information to multicast router, sending strategy request to strategy control system by multicast router, the strategy making answer by judging the permission of user accessing, sending back strategy instruction, the multicast router making relative operation according to strategy instruction and dynamically modifying control list, the user obtained permission can access multicast, said invention has fine expandability.

Description

Technical field: [0001] The invention relates to the field of Internet security multicast, and is used for a method for controlling the access of multicast participants when they access multicast groups. Background technique: [0002] Multicast technology can save network resources and is convenient to use in one-to-many and many-to-many situations. Multicast technology is increasingly applied to various broadband services, such as news on demand, video conferencing, and so on. Wherein: a multicast participant (MulticastParticipant) refers to a sender (Sender) or a receiver (Receiver) participating in the multicast service. A multicast member refers to a receiver that joins a multicast group. Access refers to the operation of connecting to a multicast domain and participating in multicast services. Join (Join) refers to the operation of a user becoming a multicast member. [0003] Figure 1 shows a network topology diagram of a multicast service. The multicast source (se...
