P802.1Qcz – Congestion Isolation

March 15, 2023

This amendment specifies protocols, procedures and managed objects that support the isolation of congested data flows within data center environments. This is achieved by enabling systems to individually identify flows creating congestion, adjust transmission selection for frames of those flows, and signal to neighbors. This mechanism reduces head-of-line blocking for uncongested flows sharing a traffic… read more »

IEEE 802/IETF Data Center Workshop – Bangkok, 2018-11-10

December 14, 2018

In November 2018, the IEEE 802 and IETF are meeting on consecutive weeks at the same hotel in Bangkok, Thailand. This fortuitous schedule allows a unique opportunity to assemble key technologists from both organizations to discuss and explore new and developing standardization activities for the Data Center environment. The IEEE 802/IETF Data Center Workshop of 10… read more »

P802.1Qcr – Bridges and Bridged Networks Amendment: Asynchronous Traffic Shaping

November 14, 2021

The full title of this PAR is “Standard for Local and Metropolitan Area Networks – Bridges and Bridged Networks Amendment: Asynchronous Traffic Shaping”. This project specifies procedures and managed objects for bridges and end stations to perform asynchronous traffic shaping over full-duplex links with constant data rates. Asynchronous traffic shaping can be modeled as an… read more »

802.1Qaz – Enhanced Transmission Selection

September 22, 2017

The full title of this PAR is “IEEE Standard for Local and Metropolitan Area Networks—Virtual Bridged Local Area Networks – Amendment: XX: Enhanced Transmission Selection.”. This standard specifies enhancement of transmission selection to support allocation of bandwidth amongst traffic classes. When the offered load in a traffic class doesn’t use its allocated bandwidth, enhanced transmission… read more »

802.1Qau – Congestion Notification

September 22, 2017

The full title of this PAR is “IEEE Standard for Local and Metropolitan Area Networks—Virtual Bridged Local Area Networks – Amendment: 10: Congestion Notification.”. This standard specifies protocols, procedures and managed objects that support congestion management of long-lived data flows within network domains of limited bandwidth delay product. This is achieved by enabling bridges to… read more »
