IP技术已经成为人们构建下一代网络(NGN)的基础,而不断增大的带宽,以及开放、统一、灵活的业务接口,已为新业务的实现提供了有力的保障,但基于软交换和分组交换(Packet Switching)技术为核心的下一代网络(NGN)的发展和部署却迟迟没有正式开始商用。究其原因,乃是下一代网络所涉及的不仅只是单一的电信网络技术,而是关系到整个通信网络的未来构架和发展方向如今,随着运营商开始构建下一代网络,下一代网 IP technology has become the foundation for building next generation networks (NGNs). Increasing bandwidth, as well as open, unified and flexible service interfaces have provided a strong guarantee for the implementation of new services. However, based on softswitch and grouping The development and deployment of next generation networks (NGNs) at the heart of Packet Switching technology have not yet officially begun commercialization. The reason is that next-generation networks involve more than just a single telecommunications network technology, but the future of the entire communications network architecture and direction Now, as operators begin to build next-generation networks, the next generation of networks
