Study Of Video Network Monitor System's Self-organization

With gradual improvement of system function, video network monitor system is playing an important role in various industry applications in China. After finishing digitization and networking, it is an inexorable trend that video network monitor system is developing from centralized to distributed and decentralized, as well as from manually-operated to self-organized and intellectualized.Begin with analyzing needs of video network monitor system for provincial freeways, a self-organized video network structure which is applicable to WAN service management is designed. The system is based on united authority on the whole network, network resource scheduling protocol, video transmission protocol, and database synchronization technology, and has the functionality of self-management of nodes and terminals, and self-routing.In this paper, current system structures and applications of video network system is analyzed. And new challenges for the system under the situation of fast development of every industry are brought out. Then the self-organizing system is defined, and its application on network is introduced. The paper is focusing on the self-organizing mechanism designs and its implementations. Key technologies such as authority management, video transmission link design and databases synchronization are analyzed in details. Based on these technologies, self-recognizing, auto joining, auto working, and auto polling-out are implemented. This system makes users get rid of static manual configurations, also makes the platform more expandable, the managements more efficient.The feature of self-route has been practiced in freeway managements in Jiangsu Province by department of communication. And the whole system behaves well. Meanwhile, this system has a broad universality. It could meet needs of many other industries through appropriate adjustments. Thus, the system is meaning and has a great research value.
