%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.
