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.
public loop An arbitrated loop that includes a participating FL_Port and can contain both public and private
NL_Ports.
Q
QuickLoop A Brocade software product that allows multiple ports on a switch to create a logical loop. Devices
connected via QuickLoop appear to each other as if they are on the same arbitrated loop.
R
R_A_TOV Resource allocation timeout value. The maximum time a frame can be delayed in the fabric and still be
delivered. See also E_D_TOV.
route As it applies to a fabric, the communication path between two switches. Might also apply to the specific
path taken by an individual frame, from source to destination. See also FSPF.
routing The assignment of frames to specific switch ports, according to frame destination.
S
S_ID Source ID. Refers to the native port address (24 bit address).
SAN Storage area network. A network of systems and storage devices that communicate using Fibre Channel
protocols. See also fabric.
SCSI Small Computer Systems Interface. A parallel bus architecture and a protocol for transmitting large data
blocks to a distance of 15 to 25 meters.
sectelnet A protocol similar to telnet but with encrypted passwords for increased security.
Secure Fabric
OS
An optionally licensed Brocade feature that provides advanced, centralized security for a fabric.
security policy Rules that determine how security is implemented in a fabric. Security policies can be customized
through Brocade Secure Fabric OS or Brocade Fabric Manager.
sequence A group of related frames transmitted in the same direction between two N_Ports.
server A computer that processes end-user applications or requests.
session The connection between the Web Tools client and its managed switch.
SFP Small-form-factor pluggable. A transceiver used on 2 GB/sec and 4 GB/sec switches that replaces the
GBIC.
