acbs造句

• On the study of the datasheet of a switching chip of dune networks , this thesis focuses on several aspects as below : improving the architecture of the msm 3 - stage clos network , designing two scheduling algorithms : acbs and cbstdm , construction of a general model for simulation , and discussing the simulation results . simulation results show that this improved architecture and scheduling algorithms can achieve high performance . first , this thesis deals with the basic theories of switching technologies including switch fabrics and scheduling algorithms and looks forward to the future of this field
  针对以上问题,本文的主要贡献和创新在于:通过对dunenetworks公司某交换芯片的研究,对msm型三级clos结构做出了改进;设计了以业务特性为导向的两种调度算法: acbs ( asynchronouscredit - basedscheduling )算法和cbstdm ( credit - basedschedulingwithtdm )算法;搭建了通用的仿真模型实现两种算法,对其进行了多方面的仿真实验并对算法性能进行了分析和讨论。
• Third , on the base of the improved architecture , two scheduling algorithms have been designed : acbs and cbstdm , which both are distributed traffic scheduling schemes and totally different from the traditional fabric scheduling schemes . the traditional fabric scheduling algorithms push the data towards egress ; however , acbs and cbstdm pull data from ingress . in acbs , ingress and egress transfer asynchronous control messages to finish distributed “ one - hop ” scheduling
  再次,在改进结构基础上设计了两种调度算法acbs和cbstdm ,两种算法均属于流调度算法,采用分布式的调度方式,与传统的用于多级结构的集中式两次匹配的调度算法有很大的区别,传统算法将输入端口的数据包“推”向交换结构的输出端口,而acbs算法和cbstdm算法是通过输出调度器将数据包从输入端口“拉”向输出端口。
