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.
