Directories for networks with casually connected users

In computer networks with decentralized control, it is necessary to provide a directory service which enables users to discover dynamically the location of other users. The authors examine the protocols for maintaining consistent directory information for casually connected users that can connect and disconnect from the network at will. They propose protocols for both hierarchical and nonhierarchical directory systems. The protocols do not rely on sequence numbers and consequently do not require 'safe store' at the user.<
