Abstract
This paper describes a general purpose name server for Tcl-DP. This name server
maintains host addresses and port numbers of services running in a distributed
environment and allows clients to query about them. It starts services on demand
so services are guaranteed to be available, and it provides a simple authentication
protocol for better security. The Tcl-DP name server is also designed to be fault-tolerant.
Multiple backup servers can be started on different hosts, and a failover occurs
when the main server goes down. In addition, the name server provides mechanisms
to interface with external modules for extending its functionality
