Technical Field
The invention relates to the field of audio and video communication, in particular to a media high-availability system based on a media stream heat transfer mechanism.
Background
Currently, with the development of society and the progress of network, the application of audio and video communication is developed explosively, and in the system architecture level, a media forwarding server cluster is used for realizing the receiving and forwarding functions of mass media data and is the basis of the whole audio and video communication platform, so that the high availability of media distribution service directly influences the user experience effect of audio and video communication products.
After a node of a traditional media forwarding server cluster is down, the existing media session is disconnected, part of the media session cannot be recovered, and a user needs to manually initiate a corresponding media session service again to recover the failed audio/video session, which seriously affects the application effectiveness of the audio/video communication service;
in the general traditional process of the audio and video communication service, a media consumption end initiates a media consumption service to a media production end, the media production end sends a media stream to a load balancer cluster through an internet network, the load balancer cluster forwards the media stream to a certain media forwarding server in a media forwarding server cluster, and the media forwarding server forwards the media stream to the media consumption end according to negotiation information. In the traditional media stream service processing process, once a media distribution service fails in the media stream forwarding process, the currently ongoing media stream forwarding service is interrupted and cannot be automatically recovered, and only a user can initiate a communication request again to solve the problem, so that the application effect and user experience of the audio and video service are greatly influenced.
Disclosure of Invention

Further, the specific working process of the media high availability system based on the media stream live migration mechanism comprises the following steps:
s1, the media information storage service records media negotiation information after the media session negotiation is successful;
s2, the media stream production end sends the audio and video media stream to the load balancer cluster through the Internet, the load balancer cluster further sends the audio and video media stream to a healthy media forwarding service node, and the health refers to a normal working state;
s3, when capturing the upstream media stream, the flow identification service in the media forwarding service node extracts the session ID from the upstream media stream, and notifies the session ID to the media forwarding service;
s4, the media forwarding service acquires the media stream session information from the media information storage service according to the session ID, opens the corresponding port to receive the uplink media stream, and forwards the media stream to the corresponding media consumption end, the media packet carries the downlink media stream session ID when forwarding;
s5, the load balancing service cluster continuously executes the health check operation on all media forwarding service nodes in the media forwarding service cluster, and when a certain media forwarding service node works abnormally, redistributes the uplink media stream currently distributed in the media forwarding service node to other healthy media forwarding service nodes.
Further, the media negotiation information in S1 includes an uplink media stream session ID, a downlink media stream session ID, a correspondence between the uplink media stream session ID and the downlink media stream session ID, a local media receiving port, a media consuming end IP, and a media consuming end port.
Further, the media stream in S2 carries the upstream media stream session ID in the form of media packets.
Further, the media stream session information in S4 includes an upstream media stream session ID, a downstream media stream session ID, a corresponding relationship between the upstream media stream session ID and the downstream media stream session ID, a local media receiving port, a media consuming end IP, and a media consuming end port.
The invention has the advantages that the invention provides a high availability scheme of media stream which is not perceived by users, and the media flow of the nodes which are down can be transferred to the normal nodes in a very short time under the condition that a plurality of nodes in the cluster are down, and the media service is automatically recovered in the normal nodes, thereby realizing the high availability of the media stream which is not perceived by users.
