随着社会不断信息化,通信网络在人们的生活中越来越普及。近年来,数据通信和IP业务不断发展,IP网络大多是以分组交换为基础的,这样的IP网络具有简单开放的特点,在人们生活中被应用得越来越广泛。未来的各项通信业务都有可能回归于IP网络上,传统的通信方式也将过渡到下一代网络,即NGN,NGN网络是以数据业务尤其是IP业务为核心的,以TCP/IP为基础,这种通信网络模式极有可能成为所有通信业务的承载体。H.248协议作为一种新型的通信协议,在通信网络中的应用将越来越广泛。
With the continuous information society, communication network in people’s lives more and more popular. In recent years, data communications and IP services continue to evolve. IP networks are mostly based on packet switching. Such an IP network has the characteristics of being simple and open and is being applied more and more widely in people’s lives. The future of all communication services are likely to return to the IP network, the traditional means of communication will also transition to the next generation network, NGN, NGN network is based on data services especially IP services as the core, based on TCP / IP , This communication network model is very likely to become the carrier of all communications services. H.248 protocol as a new type of communication protocol, the application in the communication network will be more and more widely.
