Abstract

To achieve fault tolerance through reconfiguration in mesh-connected arrays many rail networks with vastly different effectiveness and cost have been presented. The authors attempt a unified notation of these networks to allow for their comparative evaluation. They further present a method to improve the effectiveness of fault tolerant networks by combining several small switches into large crossbar switches. This method is applicable to almost all rail networks presented in the literature leading to a significant improvement of effectiveness and often also delay time along the network connections for little hardware cost. Furthermore, the switches used provide fault tolerance of the network itself, which is usually unrealistically assumed to be always fault free.<>

一种用于可重构网格的高级网络
为了通过网格连接阵列的重构实现容错,人们提出了许多效率和成本差异很大的轨道网络。作者试图统一这些网络的符号,以允许他们的比较评价。他们进一步提出了一种通过将几个小交换机组合成大型交叉开关来提高容错网络有效性的方法。该方法几乎适用于文献中提出的所有轨道网络,从而显著提高了效率,并且通常会以较小的硬件成本延迟网络连接的时间。此外,所使用的交换机提供网络本身的容错能力,通常不切实际地假设它总是无故障的
