软件简介

Abstract:
This standard is part of a family of standards for local area networks (LANs) and metropolitan
area networks (MANs) that deals with the Physical and Data Link Layers as defined by the
ISO Open Systems Interconnection Reference Model. It defines a high-speed shared medium
access protocol for use over a dual, counterflowing, unidirectional bus subnetwork. The Physical
Layer and Distributed Queue Dual Bus (DQDB) Layer are required to support a Logical Link Control
(LLC) Sublayer by means of a connectionless Medium Access Control (MAC) Sublayer service
in a manner consistent with other IEEE 802 networks. Additional DQDB Layer functions are specified
as a framework for other services. These additional functions will support Isochronous Service
Users and Connection-Oriented Data Service Users, but their implementation is not required for
conformance.
