Multilevel streaming media packet forwarding method

Abstract

The invention belongs to the technical field of video monitoring, and provides a multilevel streaming media packet forwarding method. The method is applied to a low-altitude low-speed small-target security video monitoring subsystem. A multilevel cascade system structure is adopted in the system. The method includes the steps that streaming media load upper limit vectors are set; video retrieval request commands are received, and users are distinguished; a data source server set and a server set to be selected are labeled; streaming media forwarding is conducted for different users and by the combination of the current load condition of the data source server set and the current load condition of the server set to be selected, and load balance adjustment needs to be conducted in necessary. The multilevel cascade system structure is adopted, the utilization rate of resources of a backbone network is increased, and intelligent unified access of the users is achieved by packet dividing of role tasks of servers; meanwhile, a streaming media packet scheduling forwarding algorithm is put forward, resources of each server are fully utilized, and high real-time performance and concurrency of the system are achieved.

Description

technical field [0001] The invention belongs to the technical field of video monitoring, and in particular relates to a method for forwarding multi-stage stream media packets. Background technique [0002] In the low-altitude slow-speed small target security system, real-time video surveillance requires the system to have high concurrency, real-time performance, and easy access to the platform. The existing low-altitude, slow-speed and small-target security video surveillance system generally adopts a single-level tree structure. Users in a control command center can access the information of the same video station. If m users access the information at the same time, then it needs to occupy m shares of backbone Network bandwidth, network resources occupy a large amount, and a server in the command center needs to complete all functions such as retrieval and forwarding. In this environment, the system concurrency, real-time performance, and platform accessibility are insuffic...
