Research On Application Of IP Multicast Technology In The Campus Network

Internet leads modern communication technology into a unified IP network by integrating all kinds of communication methods. Internet has already gradually developed from a single data transferring network to an integrated network that transfers multimedia such as data, audio, video. Its application field spreads continuously. But, increasingly enormous network services starts to bring huge crisis such as exhausted bandwidth over internet.IP multicast technology marks a multicast communication group by using D class IP address, which can transfer data more effectively. All the hosts in the IP multicast communication can join or exit from its multicast communication group freely because no matter how many target addresses there are, only one data package can be transferred on one data route. Due to IP multicasting communication technology can effectively alleviate bandwidth bottleneck, application based on IP multicast has gained more and more attention.As an application, we develop a campus network. The main contribution of this paper is as follows:1. Apply IP multicast technology in the campus network condition by establishing a network video living broadcast.2. By monitoring and analyzing the IP multicast conditions, Optimize this application project, make it work more effectively.3. By analyzing the existent problems and difficulties of IP multicast, we give some practical proposals to its security reliability the IP multicast authentication and its billing system.4. Introduce a designation process for applying IP multicast communication in a campus network.
