Design And Implementation Of Distributed Video Storage System

With the development of video compression technology and computer network technology, video surveillance technology transform analog into today's digital network. However, the function of digital video server is very single, unable to meet the needs of modern security industry. A new generation of video surveillance storage systems should be a comprehensive and complete platform. This article comes from the video surveillance project which is applied on the highway.After analysis of characteristics of the project's own scene, this paper mainly introduced from the perspective of software design of video storage server program design and implementation. Video data is sent to the client via TCP in order to increase the fluency of the video; via RTP in order to increase real-time. In addition, the video store and other stores in different ways, has its own characteristics and problems, 512 concurrent storage tests the system I/O throughput, a mass data storage brought the search and scheduling problems, In order to solve these two problems, we also give a detailed study.With the use of distributed middleware technology, all servers in the network form a tree structure, so that the expansion of the entire system is greatly increased. Through the use of subscription and distribution mechanism to achieve the video conferencing is one of the highlights of this system. While achieving user management, log management, data backup and other functions, so this system is a very completed video surveillance and storage application platform.Finally, this paper test results show that the various functions to achieve the expected goal, and now the system has stable operation of the highway.
