7. Glossary of Terms

ARP: Address Resolution Protocol
CBS: Committed Burst Size
CIR: Committed Information Rate
CLI: Command Line Interface
DHCP: Dynamic Host Configuration Protocol
DIP: Destination IP address
DMAC: Destination MAC address
DSCP: Differentiated Services Bode Point
IPv4: Internet Protocol v4
IPv6: Internet Protocol v6
LAN: Local Area Network
MAC: Media Access Control
MPLS: Multiprotocol Label Switching (MPLS) is a routing technique in telecommunications networks that directs data from one node to the next based on labels rather than network addresses.
N.A.: Not Available / Not Applicable
PCP: Priority Code Point
PRBS: Pseudorandom Binary Sequence is a binary sequence that, while generated with a deterministic algorithm, is difficult to predict and exhibits statistical behavior similar to a truly random sequence.
SES: Severe Errored Second
SMAC: Source MAC address
TC: Traffic Class
TCP: Transmission Control Protocol
TG: Traffic Generation
TPID: Test Payload ID
TPLD: Test Payload Data. Each Xena test packet contains a special proprietary data area called the Test Payload Data, which contains various information about the packet. The TPLD is located just before the Ethernet FCS.
UDP: User Datagram Protocol
UI: User Interface
UNI: User-to-Network Interface
VID: VLAN ID
VLAN: Virtual local area network (VLAN) is any broadcast domain that is partitioned and isolated in a computer network at the data link layer (OSI layer 2).
