Analysis of improved contention resolution algorithms and throughput over rac 随机多址信道冲突分解算法及吞吐量分析
In this paper , the technique of contention resolution in optical packet switching will be studied 本文将对光分组交换中的波长域和时间域两种竞争解决技术进行研究。
As the critical technology of ops , optical buffers can reduce loss probability and enhance switching efficiency , especially while dealing with the problem of contention resolution 光缓存技术是光分组交换的关键技术之一,尤其是对于交换中的竞争冲突解决,引入光缓存可以有效的降低丢包率,提高交换效率。
In the part of contention resolution in wavelength domain , the schemes of contention resolution with wavelength conversion , spc ( single - per - channel ) , spl ( share - per - link ) and spn ( share - per - node ) are analyzed and compared 在波长域的竞争解决研究中,首先对spc 、 spl和spn三种共享波长转换器结构的竞争解决方案进行了仿真分析。
Introduces multi - user access , slot alignment and power control , contention resolution . presents the multi - user access method based on cdma employed in the backward link . then we give a brief compare to the m - serial , gold - serial and walsh - serial 介绍了多址接入技术,讨论了接入模式、时隙同步和功率控制、冲突解决的办法,提出了基于cdma的反向链路多用户接入技术。
