Data forwarding system and method of streaming media forwarding server

Abstract

The invention provides a data forwarding system and method of a streaming media forwarding server, and relates to the technical field of the Internet. The method comprises the following steps that thestreaming media forwarding server receives audio and video data sent by each media source, adds the audio and video data into a circular buffer queue in a circular coverage manner by taking a frame as a unit, and respectively stores frame information of each frame of audio and video data into a frame data node list and a media source node list; and the streaming media forwarding server receives adata reading request including the media source number sent by the client, sequentially reads the frame data node list corresponding to the media source number and the frame information in the framedata node list, and reads the audio and video data from the circular cache queue according to the frame information. The invention has the beneficial effects that the memory utilization rate of the streaming media forwarding server is effectively improved; the data receiving and forwarding are separated, and the problems of network congestion and the like are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a data forwarding system and method of a streaming media forwarding server. Background technique [0002] Streaming media forwarding refers to a module that obtains audio and video data from network devices, and then forwards the audio and video data to each client. The existing streaming media forwarding module generally pre-allocates enough memory of one frame data length for each streaming media network link to receive network data, or dynamically allocates memory according to the data length. The former may cause low memory utilization, while the latter has It is easy to cause severe memory fragmentation. If streaming media data forwarding is blocked, it will cause problems such as blocking the entire link network. [0003] The data size of each frame of the video is inconsistent. If the memory pre-allocation for receiving audio and video data from the network is too l...

AI Technical Summary

Problems solved by technology

The existing streaming media forwarding module generally pre-allocates enough memory of one frame data length for each streaming media network link to receive network data, or dynamically allocates memory according to the data length. The former may cause low memory utilization, while the latter has It is easy to cause severe memory fragmentation

If streaming media data forwarding is blocked, it will cause problems such as blocking the entire link network

[0003] The data size of each frame of the video is inconsistent. If the memory pre-allocation for receiving audio and video data from the network is too large, it will cause waste of resources; if the pre-allocation is too small, the memory cannot save the complete frame data; Data size dynamically allocates memory, which will lead to serious memory fragmentation

Furthermore, the asynchronous processing of audio and video data network reception and forwarding without buffering will lead to a series of problems such as the entire link network congestion, the network buffer area becoming larger, and the network smoothing.
