6 Glossary
iSCSI: Internet Small Computer System Interface. iSCSI is a protocol that uses TCP to transport SCSI
commands for a storage network, enabling existing TCP/IP Infrastructure to be used as a SAN
FCoE: Fibre Channel over Ethernet
DCB: Data Center Bridging
DCBX: DCB eXchange protocol
ETS: Enhanced Transmission Selection
PFC: Priority-based Flow Control
LAN: Local Area Network
SAN: Storage Area Network
CNA: Converged Network Adapter
Ethernet: Ethernet is a physical and data link layer technology for LANs
MAC: Media Access Control address is a unique identifier assigned to network interfaces for
communications on the physical network segment
CoS: Class of Service is a way of managing traffic in a network by grouping similar types of traffic (for
example, e-mail, streaming video, voice, large document file transfer) together and treating each type
as a class with its own level of service priority. Unlike Quality of Service (QoS) traffic management,
Class of Service technologies do not guarantee a level of service in terms of bandwidth and delivery
time; they offer a "best-effort."
QoS: Quality of Service (QoS) is a set of technologies for managing network traffic in a cost effective
manner to enhance user experiences for home and enterprise environments. QoS technologies allow
you to measure bandwidth, detect changing network conditions (such as congestion or availability of
bandwidth), and prioritize or throttle traffic.
TLV: Type-Length-Value or Tagged-Length-Value
