what is data centre bridging
IEEE 802.1 Data Center Bridging (DCB) is a collection of standards that defines a unified 802.3 Ethernet media interface, or fabric, for local area network (LAN) and storage area network (SAN) technologies.CBX is also used to detect conflicting QoS parameter settings between the network adapter (local peer) and the remote peer. Based on the local and remote QoS parameter settings, the miniport driver resolves the conflicts and derives a set of operational QoS parameters.
Data center bridging (DCB) refers to a set of enhancements to Ethernet local area networks for use in data center environments, in particular for use with clustering and storage area networks.Contents.owever, Ethernet is designed to be a best-effort network that may experience packet loss when the network or devices are busy. In Internet Protocol networks, transport reliability under the end-to-end principle is the responsibility of the transport protocols, such as the Transmission Control Protocol (TCP).
