System and method for multicast traffic control management

Abstract

The invention discloses a multicast flow control and management system, comprising an Internet group management protocol (IGMP) snooping module, a command line interface (CLI), a web interface, a setting manager, an event manager, a cycle service manager, a router hardware abstraction layer (RT_HAL) module, a data packet transmitter module and an exchanger driver. The IGMP snooping module is used to transmit the multicast data packet needed by host computers in network connection and receives the join or leave data packet transmitted from the data packet transmitter module to determine which host computers need join the multicast group and which ones need leave the multicast group. The RT_HAL module forms a forwarding list according to the join data packet and by this forwarding list, the IGMP snooping module can determine to transmit the received multicast data to the response host computers.

Description

【Technical field】 [0001] The invention relates to a data communication network, in particular to a multicast flow (Multicast Flooding) control and management system and method. 【Background technique】 [0002] With the widespread use of personal computers and the increasing popularity of local area networks, computers and networks themselves are gradually improving. On the Internet, multimedia services such as streaming media (Streaming Media), video conferencing, and video-on-demand are becoming an important part of information transmission, and network traffic will increase, so devices that allow large amounts of data to be transmitted on high-speed networks are also Growing. The unicast method of point-to-point transmission can no longer adapt to the characteristics of this type of business transmission - single point transmission and multiple point reception, because the server must provide each receiver with a copy of the IP message with the same content, and at the sam...

Problems solved by technology

Moreover, it is difficult to distinguish which ports need to receive multicast data packets and which ports do not need to receive multicast data packets for multimedia data packets transmitted, so multicast data packets will be sent to all ports

Due to the continuous data flow and the large amount of data are moving images in many cases, this leads to a great limitation of the communication control unit, that is, the data processing rate becomes slower, the transmission time becomes longer, and it also affects the transmission of unicast data packets
