摘要

许多路由和波长分配算法已被提出用于光网络,但它们缺乏能够进一步共享每个波长的千兆带宽的改进。显然,TDM波长路由网络可以提供比传统波长路由网络更好的网络吞吐量。然而,随着光学技术的进步,可以将光纤中的波长划分为时隙,并进一步将时隙划分为小时隙,从而可以更有效地利用光纤带宽。本文提出了一种带电子系统控制器的路由器结构,以支持路由每一跳在一个波长的时隙的小时隙上的光数据传输。在所提出的路由器架构中不使用波长转换器。通过仿真验证了该网络在阻塞概率和吞吐量方面的有效性

A Mini-Slot Router Architecture for TDM Optical WDM Networks
Many routing and wavelength assignment algorithms have been proposed for optical networks, but they lack the refinement of being able to further share the gigabit bandwidth in each wavelength. Obviously, TDM wavelength routing networks can offer better network throughput than traditional wavelength routed networks. However, with the advancement of optical technology, it is possible to divide a wavelength in a fiber into time-slots, and further divide a time-slot into mini-slots so that the fiber bandwidth can be more efficiently utilized. This paper proposes a router architecture with an electronic system controller to support optical data transfer at the mini-slots of a time-slot in a wavelength for each hop of a route. No wavelength converter is employed in the proposed router architecture. The effectiveness of this network in blocking probability and throughput is demonstrated by simulation
