IGMP/MLD (Internet Group Management Protocol/Multicast Listener Discovery) multicast control protocol-based multicast control system and control method

Abstract

The invention relates to an IGMP / MLD (Internet Group Management Protocol / Multicast Listener Discovery) multicast control protocol-based multicast control system. The system comprises data communication equipment, a client and a plurality of multicast objects which support the IGMP / MLD multicast control protocol; the data communication equipment comprises a message receiving unit, a message forwarding unit, a message information extraction unit, a message information storage unit and a message information detection unit; and the message information storage unit is a multidimensional information structure storage unit. The invention further relates to an IGMP / MLD multicast control protocol-based multicast control method which uses the system, wherein the message information extraction unit is used for extracting the package information of multicast messages and for storing the package information in the multidimensional information structure storage unit; and the message information detection unit is used for authenticating multicast from a plurality of dimensionalities, so that the traditional method for detecting multicast messages is simplified, the complexity for the detection is lowered, the degree of modularization for multicast control is enhanced, and the stability and the maintainability of the data communication equipment are ensured.

Description

technical field [0001] The present invention relates to the technical field of data communication, in particular to the technical field of multicast control, in particular to a multicast control system and control method based on the IGMP / MLD multicast control protocol. Background technique [0002] In the field of communication technology, multicast is a very important type of service. Operators often check the multicast access of users. This is because there are various types of users. Only users who meet the rules of the operator , the multicast service of the operator can be used normally. And these operator rules are also diverse, only specific devices, specific ports, specific VLANs (Virtual Local Area Network Virtual Local Area Network), specific time periods, specific clients, specific multicast addresses, etc. meet the requirements of operator rules , the multicast service can be used. Communication equipment using multicast services needs to be checked against va...

AI Technical Summary

Problems solved by technology

Communication equipment using multicast services needs to be checked against various conditions, and the complexity of various rule checks is very high, and different rules are likely to interfere with each other, which makes the implementation and testing of device functions more complicated. The stability of the device is poor
