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 en- vironment 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.
