Status of this Memo


   This memo provides information for the Internet community.  It does
   not specify an Internet standard of any kind.  Distribution of this
   memo is unlimited.

Abstract

   This memo contains an algorithmic description of the rules used by an
   RSVP implementation for processing messages.  It is intended to
   clarify the version 1 RSVP protocol specification.

   This memo provides a generic description of the rules for the
   operation of Version 1 of RSVP [RFC 2205].  It is intended to outline
   a set of algorithms that will accomplish the needed function,
   omitting many details.

1. GENERIC DATA STRUCTURES

   This memo assumes the generic interface calls defined in [RFC 2005]
   and the following data structures.  An actual implementation may use
   additional or different data structures and interfaces.  The data
   structure fields that are shown are required unless they are
   explicitly labelled as optional.

   o    PSB -- Path State Block

        Each PSB holds path state for a particular (session, sender)
        pair, defined by SESSION and SENDER_TEMPLATE objects,
        respectively, received in a PATH message.
