Research And Implementation Of Multicast Technology Of Police Network Streaming Media Service

In recent years, the development of the national police network education, breaking the traditional mode of police education training, but also more and more accepted by the police, With the increasing of video courses in the national public security network education college, existing unicast transmission has been unable to meet the needs of users, often Caton, response time is too long.IP multicast technology has matured in the traditional IPV4 network, and has become the first choice for IPTV and other streaming media applications. Aiming at the characteristics of the video course and the special characteristics of the public security network, the IP multicast technology is the best choice for the transmission media.Based on the actual situation of police network, combining with the multicast technology, this paper analyzes the existing network environment, and focuses on the network environment, needs and applications, and the selection of multicast protocol, and the part of the implementation of multicast technology.At last, the paper expounds the standard and requirement of multicast network. After the comprehensive analysis of the multicast operation, according to the specific situation of the multicast deployment to do the details, to ensure the control and security of multicast, including multicast source control, multicast security configuration, QoS design and deployment. The test and test method of multicast deployment are presented to verify the stability and availability of the multicast deployment in police network. In this paper, the research on multicast technology is of great significance to the implementation of the national police service.
