eXtensible Service Subscription Protocol (XSSP)
UC3M
This document specifies the eXtensible Service Subscription Protocol (XSSP), a lightweight protocol that allows XSDF Agents to be subscribed to the Service information repository. XSDF subscribed Agents are notified when any change occurs. Directory Agents from the same Realm are subscribed among them in order to synchronize the common Service repository. XSSP is one of the protocols of the eXtensible Service Discovery Framework (XSDF).
