IEEE 802.6j-1995 IEEE Standard for Local and Metropolitan Area Networks: Supplement to IEEE Std 802.6,1994 Edition - Connection-Oriented Service on a Distributed Queue Dual Bus (DQDB) Subnetwork of a Metropolitan Area Network(MAN)
Amendment by IEEE, 10/17/1995

Full Description

Scope

This standard is a supplement to ISO/IEC 8802-6: 1994. Applications requiring bandwidth guarantees and delay limits are common and the need has been identified to support such applications on a DQDBsubnetwork. Those requirements can be achieved by using either the Pre-Arbitrated (PA) functions (see IEEE Std 802.6h-19931) or the Queued Arbitrated (QA) functions. This standard focuses on the use of enhanced QA functions.The Guaranteed Bandwidth (GBW) protocol is specified as an enhancement of the QA Functions block.Moreover, Connection-Oriented Convergence Functions (COCFs) using the enhanced QA functions arenecessary to support connection-oriented service. Different COCFs optimized for different types of applications are envisaged on top of the QA Functions block, using for example, AAL3/4 or AAL5.However, in this standard, only the COCF block using AAL3/4 is fully specified.This standard does not specify procedures for establishing, maintaining, and releasing connections.

Abstract

Amendment Standard - Inactive-Withdrawn.Enhanced Queued Arbitrated (QA) Functions, which can support applications requiring bandwidth guarantees and delay limits on a DQDB subnetwork, are specified. Connection-Oriented Convergence Functions (COCFs) using the enhanced QA Functions, which are necessary to support connection-oriented service, are also specified.
