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.
