%X To date, practical experience in constructing switching
networks using IEEE 1355 technology has been confined to
relatively small systems and there are no experimental
results on how the performance of such systems will scale up
to several hundred or even several thousand nodes. Some
theoretical studies have been carried out for large networks
of up to one thousand nodes for different topologies. We
present results obtained on a large modular testbed using
100 Mbits/s point to point DS links. One thousand nodes will
be interconnected by a switching fabric based on the 32 way
STC104 packet switch. The system has been designed and
constructed in a modular way to allow a variety of different
network topologies to be investigated (Clos, grid, torus,
etc.). Network throughput and latency are being studied for
various traffic conditions as a function of the topology and
network size. Results obtained with the current 656 node
setup are presented.
