Bandwidth

The amount of data per second that can be transferred from one device to another. Bandwidth limits are set by a combination of speed of transfer, capacity of the pipe, number of pipes, and overhead of sending the data. It is possible to transmit one signal at the maximum specified bandwidth, or several different signals simultaneously on different channels, each of them using a portion of available bandwidth.

BLS

Basic Link Services (also known as Link Service). A Fibre Channel request/ response protocol common to all devices. The most universally implemented Basic Link Service is Abort Sequence (ABTS), used for error recovery.

Broadcast

A transmission sent to all N_Ports on a network.

Bypassed port

A port status that indicates a port is not enabled on a loop, even though the port is still physically connected to the network. A bypass can be automatic or manual.

Channel

A pathway between components in a computer system or between workstations in a network.

Cluster

A group of systems that work together as a single system to provide fast, uninterrupted service. It is a way to increase capacity and to add I/O bandwidth.

Credit

A numeric flow control value that establishes advance permission to send one or more frames. It is used for either end-to-end or buffer-to-buffer Class-2 frames. As long as a port has a credit of greater than 0, it is able to continue to send frames. Credit is granted by a port during the login process.

Datagram

Datagram refers to an unacknowledged Fibre Channel frame or frame sequence, borrowed from networking terminology. The Fibre Channel standards use it specifically to refer to the type of unacknowledged service defined by Class 3 delivery.

See FC-AL Device.
