Glossary and acronyms
Address assignment
A process whereby addresses are assigned to switches and switch ports.
Address identifier
A 24-bit address value used to uniquely identify the source (S_ID) and
destination (D_ID) of Fibre Channel frames.
destination (D_ID) of Fibre Channel frames.
Available BB_Credit
A value used by a transmitter to determine permission to transmit frames
and, if so, how many. The transmitter may transmit a frame when the
available BB_Credit is greater than zero.

Available_receive_buffers
The current number of buffers in a receiving port that are available for
receiving frames at link rate.
receiving frames at link rate.
Arbitration Wait Timeout Value (AW_TOV)
The minimum time that an L_Port waits while arbitrating before originating a
loop initialization.

Bandwidth
The maximum information-carrying capacity of a system.
Baud
The encoded bit rate per second.

Beaconing
A continuous signaling of error conditions on a LAN. Beaconing can occur
either on the port or on one or both sides of the link (known as end-to-end
beaconing).
either on the port or on one or both sides of the link (known as end-to-end
beaconing).
Bit error rate (BER)
The probability that a transmitted bit will be received in error. The bit error
rate is expressed as the ratio of error bits to total number of bits.
