> Overview:
> Data Center Bridging is a new layer 2 networking technology
> targeted for data centers looking to converge certain network flows.
> The technology uses 802.1p priority tagging from 802.1q, and then adds
> the new 802.1Qaz Priority Grouping and 802.1Qbb Priority Flow Control
> technologies. The purpose is to provide per-priority flow control to
> individual network flows without impacting other flows. It also
> provides the mechanism to enforce bandwidth allocation per flow.
> A Wikipedia article describing the network-wide model this fits
> into can be found here:
