   This document defines the use of Service Location Protocol version 2
   (SLPv2) by Fibre Channel over TCP/IP (FCIP) Entities.

1.  Introduction

   This document describes the use of the Service Location Protocol
   version 2 in performing dynamic discovery of participating Fibre
   Channel over TCP/IP (FCIP) Entities.  Implementation guidelines,
   service type templates, and security considerations are specified.

2.  Notation Conventions

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   document are to be interpreted as described in [RFC2119].

3.  Terminology

   Here are some definitions that may aid readers that are unfamiliar
   with either SLP or FCIP.  Some of these definitions have been
   reproduced from [RFC2608] and [RFC3105].

   User Agent (UA)            A process working on the client's behalf
                              to establish contact with some service.
                              The UA retrieves service information from
                              the Service Agents or Directory Agents.

   Service Agent (SA)         A process working on behalf of one or more
                              services to advertise the services and
                              their capabilities.

   Directory Agent (DA)       A process which collects service
                              advertisements.  There can only be one DA
                              present per given host.

   Scope                      A named set of services, typically making
                              up a logical administrative group.

   Service Advertisement      A URL, attributes, and a lifetime
                              (indicating how long the advertisement is
                              valid), providing service access
                              information and capabilities description
                              for a particular service.

   FCIP Entity                The principle FCIP interface point to the
                              IP network.

   FCIP Entity Name           The world wide name of the switch if the
                              FCIP Entity resides in a switch or the
                              world wide node name of the associated

   FCIP Discovery Domain      The FCIP Discovery Domain specifies which
                              FCIP Entities are allowed to discover each
                              other within the bounds of the scope.

4.  Using SLPv2 for FCIP Service Discovery

   At least two FCIP Entities must be involved in the entity discovery
   process.  The end result is that an FCIP Entity will discover one or
   more peer FCIP Entities.

4.1.  Discovering FCIP Entities using SLPv2

   Figure 1 shows the relationship between FCIP Entities and their
   associated SLPv2 agents.
