The Data Center Bridging Task Group is part of 802.1. For general information, please refer to the 802.1 home page.
The charter of the TG is to provide enhancements to existing 802.1 bridge specifications to satisfy the requirements of protocols and applications in the data center. Existing high-performance data centers typically comprise multiple application-specific networks that run on different link layer technologies; e.g. Fibre Channel for storage, InfiniBand for high-performance computing, Ethernet for network management and LAN connectivity. The specifications from this TG will enable 802.1 bridges to be used for the deployment of a converged network where all applications can be run over a single physical infrastructure.
- Congestion Notification (CN) provides end to end congestion management for protocols that do not already have congestion control mechanisms built in; e.g. FCoE. It is also expected to benefit protocols such as TCP that do have native congestion management as it reacts to congestion in a more timely manner.
- Priority-based Flow Control (PFC) provides a link level flow control mechanism that can be controlled for independently for each priority. The goal of this mechanism is to ensure zero loss due to congestion in DCB networks.
- Enhanced Transmission Selection (ETS) provides a common management framework for assignment of bandwidth to traffic classes.
- A discovery and capability exchange protocol that is used for conveying capabilities and configuration of the above features between neighbors to ensure consistent configuration across the network. This protocol is expected to leverage functionality provided by 802.1AB (LLDP).
