Full Description

Scope

Define IEEE 802.5 Token Ring (MAC) parameters and minimal augmentation of its operation, physical layer characteristics, and management parameters for transfer of 802.5 format frames at 1,000 Mb/s or faster. The standard will consist of specifications for both stations and ports. MAC frame format will be based on that defined for IEEE 802.5. The frame format between MAC and LLC is being preserved

Purpose

To extend the IEEE 802.5 protocol to an operating speed of 1,000 Mbit/s or faster, to provide a significant increase in bandwidth while maintaining maximum compatibility with the installed base of Token Ring nodes, previous investment in research and development, and principles of network operation and management.

Abstract

Amendment Standard - Inactive-Withdrawn.This amendment specifies the changes required to IEEE 802.5, 1999 Edition (ISO/IEC8802-5:1998 base standard), IEEE Stds 802.5r and 802.5j, 1998 Edition (ISO/IEC 8802-5:1998/Amd. 1:1998), and IEEE Std 802.5t-1999, to support 1000 Mbit/s Dedicated Token Ring (DTR) operation. The base standard together with Amendment 1 specifies shared and dedicated (point-to-point) Token Ring operation at both 4 and 16 Mbit/s using either the TKP Access Protocol or theTXI Access Protocol. IEEE Std 802.5t-2000 extends Token Ring operation to 100 Mbit/s for the DTR C-Port and Station using the TXI Access Protocol. This standard extends Token Ring opera-tion to 1000 Mbit/s for the DTR C-Port and Station using the TXI Access Protocol. Extensions to the Media Access Control have been made to accommodate the requirements for the 1000 Mbit/s media rate.
