B


back-pressure

Any mechanism that slows transmission by creating congestion along the backward path.



basic link service

Special Fibre Channel procedures and frame payloads that provide basic low-level networking functions.



Bit Error Ratio (BER)

The ratio of erroneous bits to valid bits in a data stream. Minimum BER requirements are stated in Layer 1 technology specifications to indicate the minimum acceptable transmit fidelity.



block-level protocol

A protocol used to store and retrieve data via storage device constructs.



block multiplexer

One of two classes of mainframe channel protocols.



bridge

A device that operates at the OSI data-link layer to connect two physical network segments. A bridge can connect segments that use the same communication protocol (transparent bridge) or dissimilar communication protocols (translational bridge). A bridge can forward or filter frames.



byte multiplexer

One of two classes of mainframe channel protocols.
