RFC1483 defines the encapsulation of IP datagrams directly in AAL5.
Classical IP and ARP over ATM, defined in RFC1577, is targetted towards making
IP run over ATM in the most efficient manner utilizing as many of the
facilities of ATM as possible. It considers the application of ATM as a
direct replacement for the "wires" and local LAN segments connection IP
end-stations and routers operating in the "classical" LAN-based paradigm.
A comprehensive document, RFC1577 defines the ATMARP protocol for logical
IP subnets (LISs). Within an LIS, IP addresses map directly into ATM Forum UNI
3.0 addresses. For communicating out a LIS, an IP router must be used -
following the classical IP routing mode. Reference the RFCs for a full
description of this approach.
