| Abstract: | This paper introduces the present situation about IP network,methods for realizing it and prospect of IP network.Then we analyse the multimedia communication technique and applications for IP network such as video on demand,IP Phone and IP conference.Last,this paper explains the prospect and trend about the multimedia application of IP network. The technology of IP network is for group/packet exchange which is one non_facing connecting network.The ratio of using source of IP is higher than that of Switched Circuit Network (SCN) communication technology,and the expense of IP network is lower than that of SCN.Therefore people attach more importance to the research of IP network.At the same time,the operations of IP network technology come forth.We also find that the recent growth of IP networking technology has led to the need for tools that provide for the management of interconnected IP networks.Successive researches about the IP network are of important values and IP network has good prospect according to its advantages. |
