摘要
对国际、国内有关下一代网络(NGN)和下一代Internet(NGI)研究与标准化工作进展情况进行了综述,分析了各类工作的优势与不足。在探讨NGI研究策略的基础上,以四川省网络通信技术重点实验室对NGI体系结构的研究工作为基础,概要地介绍了笔者提出的"单物理层用户数据传输与交换平台体系结构"(SUPA)及"面向以太网的物理帧时槽交换"(EPFTS)技术,探讨了如何用上述技术解决Internet所面临的高速交换、服务质量保障和网络安全问题。
Comprehensive review and analysis of international research and standardization activities pertinent to Next Generation Networks (NGN) and Next Generation Internet (NGI) were provided. A strategy in developing NGI architecture was proposed based on the experience gained in development of Single physical layer User-data transfer & switching Platform Architecture (SUPA). A brief discussion on SUPA and Ethernet-oriented Physical Frame Timeslot Switching (EPFTS) was given, and how to solve QoS provisioning, high-pefformance switching and Internet security by using the techniques was also discussed.
