【摘要】 通信网上不断涌现的数据业务对带宽及服务质量(QoS)的要求正与日俱增,使得接入网的设计面临新的挑战和机遇.当前实用的一些方案可以满足近期多数用户的需求,但也仅限于传输几兆、几十兆比特的容量.从长远来看,基于波分复用(WDM)技术的宽带光接入方案将是较好的选择.更多还原

【Abstract】 A WDM-based optical access network architecture for providing broadband Internet services is described in this paper. This paper concentrates on the joint design of the electronic and optical layers so as to optimize the performance of access network. Finally, the impact of the optical topology on higher layer TCP/IP protocol family is also discussed.更多还原
