Problems solved by technology

[0004] However, most of these methods are aimed at the rate control of network congestion and have high hardware requirements, so they cannot solve the problems of server-side resource sharing and interference suppression.

Embodiment Construction

[0036] In order to solve the problems in the prior art, the present invention provides a novel interference suppression method for self-organizing streaming media servers based on feedback mechanism, see figure 1 . figure 1 Describes the architecture of the video server. 1 means that the server polls all streaming media sessions in a token ring manner; 2 means storage devices, including disks (arrays) and memory, whose function is to read media file content for use by the control and sending modules. 3 represents the transmission subsystem, which is responsible for sending media data to each client. 4 represents a code rate leveling processor; 5 represents a data rate controller; the rate controller and the code rate leveling processor are used to reflect QoS and control the sending rate. 6 represents the send data buffer of the server.

[0037] In order to ensure that the overall scheduling is as simple as possible and has good universality, the present invention adopts ro...

Abstract

This invention relates to a method for making large concurrency flow media to transfer timely. In the method, a server designs the largest number for supporting the flow media, designs the reference task progress, the current error gain and accumulated error gain for them and makes the token potting among the flow media within each frame interval. Every flow medium who gets the token judges if its current window value is zero, if not, it sends and processes data according to the send plan, if it is zero, it computes the error of the general task progress of said flow medium to design a new sending plan and degrades the current window value by 1. Said flow media server can suppress the arrive time, the number server can suppress the arrive time, the number, the wave of the code rate, hardware and network faults so as to increase the concurrency number, stability and usability supported by the server.

Description

technical field [0001] The invention belongs to the technical field of network multimedia. Specifically, it relates to a method for self-organizing and instructing large concurrent streaming media servers to transmit multimedia information in real time on the Internet fairly and effectively in network multimedia. Background technique [0002] With the rapid development of computer technology, streaming media applications are getting more and more attention. In various streaming media applications, such as video on demand (VoD), interactive television (ITV), virtual teaching, high quality and instant playback must be guaranteed. In order to ensure that each frame is decoded at a predetermined time point, a part of the video stream is pre-stored in the decoder buffer before playing. However, due to the impact of random interference and various failures, there are many problems in the process of transmitting video streams, such as data delay, data loss, and so on. Since the ...
