Multicast management method and multicast management system based on mark

Abstract

The invention relates to a multicast management system based on a mark, comprising a multicast source, a receiving node, an AR, an MC and an MR, wherein the AR is used for receiving a multicast joining request of the receiving node; the MC is used for distributing an MGI being suitable for the AR; and the MR is used for establishing a route with the AR and transmitting multicast state information to the MC. The invention realizes management based on a node mark, guarantees the safety of multicast source data entering a network, also guarantees that the node can still maintain an own multicast service state after a network access position of the node is changed and can be applied to any types of networks.

Description

technical field [0001] The invention relates to an identification-based multicast management method and system. Background technique [0002] With the rapid popularization of the Internet and the development of some high-bandwidth applications (such as video conferencing, video-on-demand, etc.), network congestion is becoming more and more serious, so people have proposed various solutions to network congestion, and multicast (Multicast) is It is one of the more advantageous technologies. Multicast is a sender or multiple senders send data to a group (multiple) receivers at the same time and only send one copy of the data. It can effectively solve the problem of data transmission efficiency encountered by traditional unicast protocols in dealing with one-to-many and many-to-many communication problems, as well as the defects of network congestion and bandwidth waste caused by broadcast technology's inability to effectively process data. [0003] However, multicast technolo...

Problems solved by technology

[0022] Although the management of specific receivers and the adjustment of multicast services can be realized by identifying nodes, multicast management should have more meanings. The multicast management functions involved in the above scheme are too simple. It is not enough to achieve comprehensive multicast management. For example, due to the lack of management and control of multicast source data, malicious nodes may flood the network with large-scale multicast data and degrade network performance. These inventions are not necessary Mechanism to establish and maintain each receiving node's usage information for a specific multicast group

From a management point of view, these methods have not established a management structure independent of the data bearing level, and the scalability is poor.
