Media data access and scheduling system architecture design method based on multi-node cooperation

Abstract

The invention discloses a media data access and scheduling system architecture design method based on multi-node cooperation. The multi-point cooperation and the unit type deployment of streaming media modules are realized through a management service module for processing signaling data and uniformly maintaining equipment of a system, and a plurality of streaming media service modules for distributing and forwarding media data, i.e. the plurality of streaming media service modules can be deployed at one same stage or an upper and lower stages so as to work cooperatively; the load balance of hardware equipment and network resources is solved effectively, the network resources are utilized maximally, the redundancy occupation of the network resources is avoided, the load balance of the system can be realized without adding third-party software or hardware, the cost on constructing the software and the hardware is reduced, and thus the method has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of video surveillance systems, in particular to a multi-node cooperation-based media data access and scheduling architecture design method that realizes load balancing of hardware devices and network loads without resorting to third-party software and hardware. Background technique [0002] In recent years, with the rapid development of computer network and multimedia technology, video surveillance technology has been widely used. The video surveillance system is used to monitor the scene environment and provide relevant image data for post-event analysis of accidents. The video surveillance system consists of encoding and acquisition equipment, communication networks and The video surveillance system software is composed of three parts. The front-end coding equipment (also known as the front-end) mainly collects, digitizes, compresses and transmits the video images; , resources, and unified management and m...

[0004] However, the load balancing of the system can be achieved through third-party software or hardware, which will increase the construction cost of the system, and because the third-party software or hardware is not related to the system business, it cannot be flexibly expanded according to business needs to maximize the load function And the effective use of hardware resources. At the same time, the media data in the video system has a large demand on the network. The load balancing method implemented by third-party software and hardware is easy to form a network bottleneck at the network exit of the load balancing device. Therefore, this method is only for the hardware. The device implements the load, but is not suitable for network load requirements

In addition, the network structure in industries such as electric power systems is usually constructed according to "superior-subordinate-front-end". When the video surveillance system software is deployed on the upper level, and both upper-level and lower-level users have video call and display requirements, it can be realized through streaming media. Media data is forwarded, but there is still redundant media data in the network segment between the "superior-lower level". At this time, the video surveillance system software can be deployed at the lower level. Module acquisition can solve the network demand for media data between "upper-level and lower-level", but it will also increase the maintenance cost of the two-level system
