eXtensible Service Location Protocol (XSLP)
UC3M
This document specifies the eXtensible Service Location Protocol (XSLP), a lightweight protocol that allows User Agents to obtain Service information from Directory Agents, even from remote domains. Also, XSLP allows User Agents to perform multicast queries to the Service Agents inside the same organization. XSLP is the main protocol of the eXtensible Service Discovery Framework (XSDF).
