What is Data Center Bridging?

Data center bridging are standard enhancements to Ethernet local area networks for use in data center environments. It primarily used in clustering and storage area networks. For computer-to-computer communications in data centers Ethernet is used as the primary network protocol.

Within the ambit of Internet Protocol networks, transport reliability under the end-to-end principle is a major responsibility of the transport protocols, such as the Transmission Control Protocol. One area of evolution for Ethernet is to add extensions to the existing protocol suite to provide reliability without requiring the complexity of Transmission Control Protocol.
