摘要

摘要: 為解決FTSA-2-SS結(jié)構(gòu)中的信元沖突、信元失序以及交換流程復(fù)雜化等問題，該文提出一種基于逆向傳輸機(jī)制的反饋型兩級交換結(jié)構(gòu)(FRTM-TSA)。該結(jié)構(gòu)通過crossbar逆向傳輸機(jī)制使得任意輸入端口均可獲得其相鄰端口的調(diào)度結(jié)果并以此對目標(biāo)端口所反饋的緩存信息進(jìn)行修正，基于修正后的信息進(jìn)行算法調(diào)度使得FRTM-TSA能夠避免信元沖突和信元失序，也無需在輸出端口設(shè)置重排序緩存。理論分析和仿真結(jié)果均表明FRTM-TSA能夠以相對簡潔的交換結(jié)構(gòu)和交換流程獲得更優(yōu)的時(shí)延性能。

Abstract: In order to solve the problems arising from the 2-Staggered Symmetry connection pattern (2-SS) in Feedback mechanism based load balanced Two-stage Switch Architecture (FTSA), a Feedback and Reverse Transmission Mechanism based Two-stage Switch Architecture (FRTM-TSA) is proposed in this paper. A novel reverse transmission mechanism of crossbar is introduced so that any input port can obtain the scheduling results of its adjacent input port. Based on such scheduling results, the buffer status information of middle-ports that received one slot ahead can be corrected. The exact information obtained from preprocessing enables FRTM-TSA to avoid the cell-conflict and cell-disordering and thus make the re-sequencing buffers are no longer needed at the output ports. Theoretical analysis and simulation experiments show that FRTM-TSA can achieve a better delay performance with a simper switching fabric and process compared to existing schemes.
