This paper describes a scalable interconnection structure for distributed computing systems. The interconnection structure is scalable in that it can serve as an I/O interconnection structure of a workstation as well as a network interconnection structure for a group or cluster of workstations.

Switcherland implements a communication model based on a distributed shared memory architecture. With it, local communication within a workstation and remote communication within a cluster of workstations translate to load and store operations which are applied to a distributed memory which resides in a single address space.

Switcherland offers quality of service (QoS) in that memory can be accessed at guaranteed rates and access times are bounded. This feature is an essential prerequisite for the integration of video and audio into a workstation environment and allows systems to treat video and audio like standard data types.
