Abstract

   This memo describes how to efficiently use the ATM call control
   signalling procedures defined in UNI Signalling 4.0 [SIG40] to
   support IP over ATM environments as described in RFC 2225 [LAUB98]
   and in RFC 2332 [LUC98].  Among the new features found in UNI
   Signalling 4.0 are Available Bit Rate signalling and traffic
   parameter negotiation.  This memo highlights the features of UNI
   Signalling 4.0 that provide IP entities capabilities for requesting
   ATM service in sites with SVC support, whether it is private ATM or
   publicly provisioned ATM, in which case the SVC support is probably
   configured inside PVPs.

   This document is only relevant to IP when used as the well known
   "best effort" connectionless service. In particular, this means that
   this document does not pertain to IP in the presence of implemented
   IP Integrated Services.  The topic of IP with Integrated Services
   over ATM will be handled by a different specification or set of
   specifications being worked on in the ISSLL WG.

   This specification is a follow-on to RFC 1755, "ATM Signaling Support
   for IP over ATM", which is based on UNI 3.1 signalling [UNI95].
   Readers are assumed to be familiar with RFC 1755.
