Clos網(wǎng)的一種會議型連接方案
A SCHEME OF CONFERENCE CONNECTION SUPPORTED BY CLOS NETWORKS

摘要: 本文提出了一種Clos網(wǎng)的會議型連接方案。該方案假定在點(diǎn)對點(diǎn)Clos網(wǎng)引導(dǎo)后,會議網(wǎng)端口以模塊為單位分配給不同會議,證明了在此條件下實(shí)現(xiàn)廣義會議非重整無阻塞和會議獨(dú)立選路需要最少的中間模塊支持,即m3。同時(shí)指出本方案具有會議成員無阻塞特性和會議不相關(guān)特性,并具有靈活性、穩(wěn)定性及時(shí)延方面的優(yōu)點(diǎn)。

Abstract: A scheme of conference connection supported by Clos networks is presented.With the assumption in this scheme,some couples of input-output switch modules of conference network are exclusively assigned to every conference,it is proved that conference non-blocking in wide sense and conference independent routing require least middle switch modules of Clos netwotk I．E．M-3．Furthermore．It is pointed out that this schene has characteristic of conference member non-blocking and conference independency,with advantages of flexibility,stability and low latency． -
