Abstract

This document describes mappings of IETF Integrated Services over LANs built from IEEE 802 network segments which may be interconnected by IEEE 802.1D MAC Bridges (switches). It describes parameter mappings for supporting Controlled Load and Guaranteed Service using the inherent capabilities of relevant IEEE 802 technologies and, in particular, 802.1D-1998 queuing features in switches.

These mappings are one component of the Integrated Services over IEEE 802 LANs framework.

1. Introduction

The IEEE 802.1 Interworking Task Group has developed a set of enhancements to the basic MAC Service provided in Bridged Local Area Networks (a.k.a. "switched LANs"). As a supplement to the original IEEE MAC Bridges standard, IEEE 802.1D-1990 [802.1D-ORIG], the updated IEEE 802.1D-1998 [802.1D] proposes differential traffic class queuing in switches. The IEEE 802.1Q specification [802.1Q] extends the capabilities of Ethernet/802.3 media to carry a traffic class indicator, or "...
