Research And Design Of The Distributed Scheduling Module In The Emergency Communications

In order to improve the ability of public security and public emergency incident handling, to prevent emergency incident from happening and reduce it's damage with best effort, to maintain national security and social stable, to promote economic development, establish a highly efficient and reliable emergency communications network is necessary.The emergency scheduling distribution module is emergency one part of the core functions, which can also referred to as the distribution center sometimes. It includes not only the function of dispatching and scheduling data, but also the gateway and firewall. One end of the gateway is linked to the router of the public network, and the other end is linked to the private network of the distribution centers. All the data through the private network is filtered by the gateway, and distributed to the Terminal Group and the database. The firewall only allows specific visit, all other unknown invaders communications are prevented. For the distribute module in the emergency communication of scheduling dispatch, On receipt of completed demands of its real-time monitoring task of server software running commands issued after data distribution, overall design according to the system requirements and agreed immediately data distribution, the latest work to get the results to designated location (designated terminal of the specified directory). So the actual operation can be understood as a document copying operation. But this kind of copy operation must be able to perform multiple files automatically copied, flexible for source, target address set and a necessary condition for the judgment, and other functions.Finally, this paper gives the development and implementation of the distributed module based on Click system, then confirm the feasibility of Click-baesd distributed scheduling module based on the experimental test...
