Application REQuested IP over ATM (AREQUIPA)
Status of this Memo
This memo provides information for the Internet community. This memo
does not specify an Internet standard of any kind. Distribution of
this memo is unlimited.
IESG Note:
This RFC has not had the benefit of the rigorous peer review that is
part of the process in an IETF working group. The technology it
describes has been implemented and is now undergoing testing. It
would be wise to analyze the results of this testing as well as to
understand alternatives before committing to this approach for IP
over ATM with QoS guarantees.
Abstract
This document specifies a method for allowing ATM-attached hosts that
have direct ATM connectivity to set up end-to-end IP over ATM
connections within the reachable ATM cloud, on request from
applications, and for the exclusive use by the requesting
applications. This allows the requesting applications to benefit in a
straightforward way from ATM's inherent ability to guarantee the
quality of service (QoS).
Given a mapping from service classes, as defined by INTSERV[6], to
ATM traffic descriptors, Arequipa can be used to implement integrated
services over ATM link layers. Usage of Arequipa to provide
integrated services even if ATM is only available for intermediate
links is not discussed in this document but should be straight-
forward.
The major advantage of using an approach like Arequipa is that it
needs to be implemented only on the hosts using it. It requires no
extra service (eg. NHRP or RSVP) to be deployed on the switches or
routers of the ATM cloud.
