摘要
单物理层用户数据传输与交换平台体系结构(SUPA)是由四川省网络通信技术重点实验室提出的、基于"面向以太网的物理帧时槽交换"(EPFTS)技术的下一代Internet(NGI)体系结构。此前对EPFTS技术的研究主要针对用户数据交换平台(U-平台)。从SUPA第二阶段过渡的需要,进一步将信控管理平台(S&M-平台)的下部两层结构简化为单层EPFTS结构,从而形成4层的S&M-平台。定义了该平台的用户-网络接口(UNI)和网络-网络接口(NNI)并对相关接口上的典型协议在新环境中进行了仿真,以证实其可行性。
Single physical layer User-data transfer & switching Platform Architecture (SUPA) is one for Next Generation Internet (NGI),which is based on Ethernet-oriented Physical Frame Timeslot Switching (EPFTS) and defined by SC-Netcom. Unlike previous work, where EPFTS was confined in User-data platform, the work presented the second phase SUPA, where both the Signaling & Management platform (S&M-platform) and U-platform are based on EPFTS. Consequently,the S&M-platform was reduced to 4 layers only. User-Network Interface (UNI) and Network- Network Interface (NNI) in this new S&M-platform were defined and simulation on typical protocols in the platform had been carried out to validate their feasibility.
