Ullod %E Peter H. Welch, Andr\[`e] W. P. Bakkers %B Proceedings of WoTUG\-21: Architectures, Languages and Patterns for Parallel and Distributed Applications %X IEEE 1355 HS\-Links and their support devices have been investigated as part of the ESPRIT projects Macram\[`e] and Arches. A description of the HS\-Link technology and initial experience with the RCube 8\-way packet router and the Bullit HS\-Link interface device are presented. A 64 node HS\-Link switching network based using these devices is being constructed at CERN. We report on the design and construction of the network testbed.
