The objective of this project is to develop effective access control / switching scheme for high speed optical fiber ring networks. This project has proposed a new control system named Resolvable-Contention Ring or simply ReC-ring. ReC-ring is based on Contention-ring, which is an integrated contention/virtual token-passing access control scheme, and introduces a resolution function of packet collision in the ring without serious hardware/software overhead. The project has constructed a specialized computer simulator for analyzing high-speed ring networks in detail and shown the effectiveness and validity of ReC-ring over other representative access control schemes, like Token-ring, Slotted-ring, and C-ring in wide range of ring network environment, quantitatively. Further, on the base of access control technology for high-speed optical ring networks, this project also has presented a new high-speed packet switching architecture by introducing multiple optical ring networks which are connected by packet overflow buffer and link. The project has shown the validity of this new architecture especially for multiple virtual links situation of multimedia data communications by both computer simulation and mathematical analysis.

本计画的目标是为高速光纤环网发展有效的存取控制/交换机制。本计画提出一种新的控制系统，称为可解竞争环（Resolvable-Contention Ring）或简称为ReC-环。ReC-ring是在竞争环（Contention-ring）的基础上提出的一种综合竞争/虚拟令牌传递的访问控制方案，并在不增加硬件/软件开销的情况下，引入了环内分组冲突的解决功能。该项目构建了一个专门的计算机模拟器，用于详细分析高速环形网络，并定量地显示了ReC-ring在广泛的环形网络环境中相对于其他代表性访问控制方案（如令牌环，时隙环和C-ring）的有效性和有效性。在高速光环网接入控制技术的基础上，通过引入多个光环网，通过分组溢出缓冲区和链路连接，提出了一种新的高速分组交换体系结构。通过计算机仿真和数学分析，证明了这种新结构的有效性，特别是对于多虚拟链路的多媒体数据通信的情况。
