摘要: 提出了一种基于编码分配的报片交换无缓冲路由器(FBEA-BLESS),通过非偏转和偏转2级分配策略来减小路由器的关键路径延时,并采用go-stop-steer (GOSS)机制来避免网络的活锁.结果表明,与基准的无缓冲路由器(BLESS)相比,所提出的FBEABLESS的网络平均延迟降低了29.4%.    

关键词: 无缓冲路由器, 报片交换, 编码分配, 交叉开关分配, 活锁

Abstract: A flit-switch bufferless router based on encoding allocation (FBEABLESS), was proposed, which can reduce the delay of critical path through two stage switch allocation with non-deflection allocation and deflection allocation. The go-stop-steer (GOSS) strategy was used to avoid livelock in the network. The simulation results show that the average delay decreases about 29.4% in the FBEA-BLESS compared with the baseline bufferless router (BLESS).

Key words: bufferless router (BLESS), flit-switch, encoding allocation, switch allocation, livelock
