Embodiment Construction

[0033] The method of the present invention carries out inspection by arranging a network fault location test system, and the system includes a data acquisition terminal Agent device, a network management computer and a database server, and the Agent, the network management computer and the database server are connected through a private network, and its architecture diagram is as follows figure 1 shown. in:

[0034]The Agent device at the data collection end is used as the server end, using a laptop or an embedded device, which runs a server-side program inside, and the device is required to run JDK 1.6 and above and have network functions. Each Agent device is required to be connected to the local area network where several video surveillance cameras are located, ensuring that it is in the same network environment as the surveillance cameras. The Agent device responds to the request message from the network management computer and sends back a test data packet to complete th...

Abstract

The invention discloses a traffic video private network fault positioning method based on an improved codebook. Polling is conducted after a network fault positioning test system is arranged, and the system comprises an Agent device, a network management computer and a database server which are connected through a private network. A video QoS threshold value is set, and the fault event detecting accuracy is improved. A codebook matrix model with three dimension parameters is adopted, and the problem that through a traditional codebook model, an annular fault relation can not be positioned is solved. The method has high scene adaptability, an existing network topological structure of the test system is not changed, and meanwhile the method has the advantages of being high in efficiency, easy to use and the like.

Description

technical field [0001] The invention belongs to the technical field of network communication, in particular to a private network fault location method based on an improved code book. Background technique [0002] A private network is an enterprise intranet, or intranet, intranet, intranet, which is a computer network that uses the same technology as the Internet. It is usually established inside an enterprise or organization and provides information sharing and communication for its members. Services such as the World Wide Web, file transfers, e-mail, etc. This kind of network does not provide services to people outside the unit. For example, military, railway, transportation and other systems all have their own dedicated networks. [0003] With the rapid development of society and economy, the carrying capacity of economic activities has continuously increased the load of expressway transportation. In recent years, due to the continuous expansion of the heterogeneous scal...
