Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

The nouns are explained as follows:

a core server: the system comprises a video network core server, a main control server and a sub-control server, wherein all services are based on the core server;

the control system comprises: the control system is developed on the flow control equipment based on the video network core server;

micro cloud number: a network formed by the master control server and all the sub-control servers connected to the master control server is a master control micro cloud, the number of the micro cloud is an identifier of the master control micro cloud, the default is 1, and the single core server is unique;

data source port, destination port, source port: that is, the sub-control servers are connected to the port numbers on the main control server, and each port number corresponds to one sub-control server. The relationship between the three can be simply understood as: the data of the sub-control server A (data source port) is transmitted to the sub-control server B (destination port), and must be forwarded by the sub-control server C (source port)

The autonomous cloud is a basic substructure in a video networking network structure and is also a minimum structural unit for enabling the video networking to normally operate. Under the condition that the configuration is correct, one autonomous cloud can independently realize all functions of the video network in the autonomous cloud. Therefore, when the autonomous cloud cannot be connected with the upper and lower autonomous clouds due to communication faults, the video networking service can still be realized in the autonomous cloud. When the autonomous clouds can normally communicate with the autonomous clouds on the upper and lower layers, the autonomous clouds form a larger range of video networking, and the video networking service crossing the autonomous clouds can be realized.

The autonomous server: the system is also called a video network master control server, is a management core of the autonomous cloud, and each autonomous cloud means at least one autonomous server. The realized functions mainly comprise management and registration of equipment in the autonomous clouds, realization of video networking service logic inside the autonomous clouds and among the autonomous clouds and management network communication of the video networking so as to realize higher-level management and the like.

A sub-control server: a video network controller integrates video network audio and video forwarding, set top box control, registration and other functions, and is installed in a box type and portable in a hand-held mode.

The video network terminal: the video network service landing equipment, the actual participants or service persons of the video network service, include various conference set-top boxes, video telephone set-top boxes, operation teaching set-top boxes, streaming media gateways, storage gateways, media synthesizers, and the like. The terminal of the video network needs to be registered on the video network server to carry out normal service. An internet-of-view number is required.
