Abstract
A set of companion documents describe an architecture for providing integrated services over low-bitrate links, such as modem lines, ISDN B-channels, and sub-T1 links [1, 2, 3, 4]. The main components of the architecture are: a set of real-time encapsulation formats for asynchronous and synchronous low-bitrate links, a header compression architecture optimized for real-time flows, elements of negotiation protocols used between routers (or between hosts and routers), and announcement protocols used by applications to allow this negotiation to take place.

Abstract
A set of companion documents describe an architecture for providing
integrated services over low-bitrate links, such as modem lines, ISDN
B-channels, and sub-T1 links [1, 2, 3, 4]. The main components of the
architecture are: a set of real-time encapsulation formats for
asynchronous and synchronous low-bitrate links, a header compression
architecture optimized for real-time flows, elements of negotiation
protocols used between routers (or between hosts and routers), and
announcement protocols used by applications to allow this negotiation
to take place.
This document defines the service mappings of the IETF Integrated
Services for low-bitrate links, specifically the controlled load [5]
and guaranteed [6] services. The approach takes the form of a set of
guidelines and considerations for implementing these services, along
with evaluation criteria for elements providing these services.
1. Introduction
In addition to the "best-effort" services the Internet is well-known
for, other types of services ("integrated services") are being
developed and deployed in the Internet. These services support
special handling of traffic based on bandwidth, latency, and other
requirements that cannot usually be met using "best-effort" service.
This document defines the mapping of integrated services "controlled
load" [5] and "guaranteed" [6] services on to low-bandwidth links.
The architecture and mechanisms used to implement these services on
such...
