Abstract

Distributed directory is an essential component in a distributed processing environment that involves multiple systems connected via a LAN (local area network) and WAN (wide area network). This paper reviews the evolution of distributed directory technology from simple name-to-address mapping to sophisticated import request-to-export service mapping by examining four different kinds of directory systems: Grapevine, Global name service, ISO Directory, and Trader. The characteristics of these directory systems with respect to their directory functions are explained. The paper concludes with a discussion on the kind of directory functions most needed in a distributed processing environment.The positions expressed in this paper are solely the views of the author and are not a reflection of IBM Canada Ltd.'s position.
