P802.1Qdt – Priority-based Flow Control Enhancements

This amendment specifies procedures and managed objects for automated Priority-based Flow Control (PFC) headroom calculation and Media Access Control Security (MACsec) protection of PFC frames, using point-to-point roundtrip measurement and enhancements to the Data Center Bridging Capability Exchange protocol (DCBX). This amendment places emphasis on the requirements for low latency and lossless transmission in large-scale… read more »

P802.1Qcz – Congestion Isolation

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

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 »

802.3bd – MAC Control Frame for Priority-based Flow Control

The full title of this PAR is “Standard for Information Technology – Telecommunications and Information Exchange Between Systems – Local and Metropolitan Area Networks – Specific Requirements Part 3: Carrier Sense Multiple Access with Collision Detection (CSMA/CD) Access Method and Physical Layer Specifications – Amendment: MAC Control Frame for Priority-based Flow Control” This standard defines… read more »

802.1Qbb – Priority-based Flow Control

The full title of this PAR is “IEEE Standard for Local and Metropolitan Area Networks—Virtual Bridged Local Area Networks – Amendment: Priority-based Flow Control.”. This standard specifies protocols, procedures and managed objects that enable flow control per traffic class on IEEE 802 full-duplex links. Data Center Bridging networks (bridges and end nodes) are characterized by… read more »

802.1Qaz – Enhanced Transmission Selection

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

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 »
