Method and device for sending data message

Abstract

The invention provides a method and a device for sending a data message, wherein the method comprises the following steps: when source network equipment is to send same data to more than two destination IP (internet protocol) addresses, a key router to the more than two destination IP addresses is determined, wherein the key router is a router through which routes corresponding to at least two destination IP addresses in the more than two destination IP addresses pass; the source network equipment notifies the key router to copy and send the data message which is sent by the source network equipment to copying IP addresses, wherein the destination IP address of the data message is a matching IP address, the copying IP addresses are the destination IP addresses of the key router through which the corresponding routes in the more than two destination IP addresses pass, and the matching IP address is one of the copying IP addresses; and the source network equipment sends the data message to a next hop key router of the source network equipment, wherein the destination IP address of the data message is the notified matching IP address of the key router. Through the method and the device, when the same data are sent to different destination equipment in a network, the network bandwidth can be saved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and device for sending data messages. Background technique [0002] The video conferencing system realizes virtual meetings through network communication technology, gathers geographically dispersed users in one place, exchanges information through various methods such as images and sounds, and carries out collaborative work. Video conferencing shortens the spatial distance to the greatest extent and facilitates real-time and intuitive communication among collaborative members. Therefore, this conference mode has been more and more widely used. [0003] In a video conferencing system, all audio and video data will be concentrated in a multi-point control unit (MCU), and then distributed to various venues after being processed by the MCU. During this process, the MCU usually distributes the same audio and video data to each site. When there are many sites j...

Problems solved by technology

However, although this method can achieve the purpose of reducing the network bandwidth occupation, since the multicast data affects all connected routers, the multicast data sent by the routers that are not routed to the site terminal is obviously redundant, such as image 3 The multicast data sent by MCU to router 2 and router 2 to router 21 and router 22 is redundant

These will obviously also take up network bandwidth and increase the burden on the router
