The CSLAN is an experiment Local Area Network based on Circuit Switching. It is made up by two kinds of nodes: switching nodes (SNs) and terminal nodes (TNs). The switching network composed by SNs provides private channels among TNs. These channels exist from the beginning of communication among TNs to the end. The topology of the CSLAN is very flexible. So the TNs have to know the topology before routing in the CSLAN. This paper discusses the topology exploring and routing problems of the CSLAN.
