Problems solved by technology

[0012] The purpose of the present invention is to provide a streaming media multicast structure and its data stream sending and receiving method, aiming to solve the problem of realizing cross-network segment multicast by configuring the IGMP protocol on the router. Due to the complexity of the IGMP protocol, the The actual engineering application has high problems for the construction personnel and users on the site

specific Embodiment

[0084] The present invention is suitable for implementation in an application system for one-way pushing of audio and video multicast service streams;

[0085] The application system is composed of multicast sources and service nodes. The network topology is as follows: figure 2 As shown; service nodes can be deployed in the same network segment as the multicast source, or distributed in different subnets;

[0086] The technical characteristics of the multicast source are:

[0087] Responsible for building and maintaining the network topology and online status of all nodes in the system;

[0088] The multicast source can actively initiate multi-channel multicast services with audio and video broadcasts in parallel, and order the relevant service nodes to enter the service receiving state through unicast, and then send the multicast service flow to the relevant service nodes in UDP mode;

[0089] The multicast source is the initiator of the system's multicast service (audio ...

Abstract

The invention discloses a stream media multicast structure and a data stream transmitting and receiving method thereof. A C/S mode is used, a steam media transmitting source is used as a server end, stream media receiving equipment is used as a client, multicast data packets can cross various different network segments in large, medium and small local area networks under the support and configuration of an IGMP protocol without a switcher or a router, and stream media IP multicast technology application is achieved. The stream media multicast structure and the data stream transmitting and receiving method thereof have the advantages that on-way transmission of multicast service streams is achieved under a cross-network-segment environment without modifying router configuration and a multicast router protocol, and the method is quite suitable for being implemented in audio-video multicast service stream on-way push application systems.

Description

technical field [0001] The invention belongs to the field of multimedia and network technologies, and in particular relates to a stream media multicast structure and a method for sending and receiving data streams thereof. Background technique [0002] Currently, streaming media technology is widely used in online news release, online live broadcast, online advertisement, distance education and other fields. If the traditional point-to-point unicast communication method is used to implement this one-to-many service, it will consume a large amount of network bandwidth and have poor scalability and deployment. The IP multicast (also called multicast or multicast) technology can send a single data packet to a specific multicast group, so that all hosts joining the multicast group can receive the data packet. Because this method can save a large amount of network bandwidth, IP multicast technology is widely used in network audio and video broadcasting, multimedia distance educa...
