2331: ATM Signalling Support for IP over ATM - UNI Signalling 4.0 Update.

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.
