Fabric OS 5.0.0 procedures user guide 259
private loop
An arbitrated loop that does not include a participating FL_Port.
private loop device
A device that supports a loop and can understand 8-bit addresses, but does not log in to the fabric.
private NL_Port
An NL_Port that communicates only with other private NL_Ports in the same loop and does not log in to the fabric.
protocol
A defined method and set of standards for communication. Determines the type of error-checking, the
data-compression method, how sending devices indicate an end of message, and how receiving devices indicate
receipt of a message.
pstate
Port State Machine.
public device
A device that supports arbitrated loop protocol, can interpret 8-bit addresses, and can log in to the fabric.
public key
The public half of a key pair. See also key , key pair .
public key cryptography
A type of cryptography that uses a key pair, with the two keys in the pair called at different points in the algorithm.
The sender uses the recipient's public key to encrypt the message, and the recipient uses the sender’s private key to
decrypt it. See also key pair , PKI .
public loop
An arbitrated loop that includes a participating FL_Port and can contain both public and private NL_Ports.
public NL_Port
An NL_Port that logs in to the fabric, can function within either a public or a private loop, and can communicate
with either private or public NL_Ports.
QoS
Quality of service.
quad
A group of four adjacent ports that share a common pool of frame buffers.
queue
A mechanism for each AL_PA address that allows for collecting frames prior to sending them to the loop.
R_A_TOV
Resource allocation time-out value. The maximum time a frame can be delayed in the fabric and still be delivered.
