.... can be used as elementary building blocks, they are potentially marketable components [6,11] Another reason behind the popularity of the mesh is that it can be partitioned into smaller areas that are still meshes, which is a desirable feature for some parallel applications [2] Wormhole routing [18] has also promoted the use of the mesh as it makes latency independent of the message distance in the absence of blocking. In wormhole routing, a message is broken into flits (typically, a few bytes each)for transmission and flow control. The header flit (containing routing information) governs ....

....requirement for interconnection networks since PNs engage in data transfers more frequently with nearby neighbors than with more distant PNs. We should note that the diameter of a network remains an important criterion in characterizing network delay even with the introduction of wormhole routing [11, 12]. Wormhole routing does not reduce the time required for intermediate PNs to process small packets (flits) Larger diameter networks must therefore keep a larger number of PNs busy for a single packet transfer [13] which leads to a reduction in throughput for the entire system. Consequently, a ....

....to high speed local area networks (LANs) 1, 2, 3] to support applications such as cluster computing that demand a very fast, high data rate communication media. 1. 1 Wormhole Routing Wormhole routing was developed from the earlier idea of cut through switching [4] and was first introduced in [5]. A wormhole routing network is composed of several switches which have relatively small input buffers (see figure 1 a) As opposed to storeand forward switching, a packet is forwarded to the next switch as soon as its header (or its routing information) is received (cut through) If the outgoing ....

A wormhole routing network is composed of several switches and hosts. Usually, wormhole routing switches have relatively small buffers.

....network configuration is shown in figure 1. Also, as shown in figure 1, we use hs link , ss link and sh link to denote host to switch, switch to switch and switchto host links, respectively. Wormhole routing is the basic switching technique we study. Wormhole routing was first introduced in [19]. It was developed from the earlier idea of cutthrough switching [10] In wormhole routing, switches have relatively small buffers. As opposed to storeand forward switching, as soon as a packet header (or its routing information) is received, this packet is forwarded to the next switch (before it ....
