Abstract
Remote service discovery refers to discovering desired services in
given remote (i.e., non-local) DNS domains. This document describes
remote service discovery in the Service Location Protocol (SLP) via
DNS SRV. It defines the DNS SRV Resource Records for SLP Directory
Agent services, discusses various issues in using SLP and DNS SRV
together for remote service discovery, and gives the steps for
discovering desired services in remote DNS domains.
1. Introduction
This document describes remote service discovery in the Service
Location Protocol (SLP) [RFC 2608] via DNS SRV [RFC 2782]. We consider
remote service discovery as discovering desired services in given
remote DNS domains, and local service discovery as discovering
desired services within the local administrative domain.
SLP provides a scalable framework for local service discovery and
selection. In SLP, User Agents (UAs) discover desired services in
the local administrative domain by querying all Service Agents (SAs)
via multicast or querying a Directory Agent (DA) via unicast. To
