glossary
aVB - A set of standards being developed by the IEEE. These standards add new time synchro-
nization and Quality of Service (QoS) functions to Ethernet.
ethernet - A widely available networking technology using CAT5/6 cabling or fiber links joined by
packet switches. Can operate at 100Mbps, 1Gbp and 10Gbps.
ieee - The Institute of Electrical and Electronics Engineers is the organization which standardizes
networking technologies like Ethernet and Firewire.
ieee 1588 - Also known as the “Precision Time Protocol”. Provides highly accurate clock synchro-
nization services in Ethernet and IP networks.
ieee 802.1 - The IEEE standards working group responsible for Ethernet protocols.
ieee 801.1aS - An Ethernet-only profile of IEEE 1588.
ieee 802.1Qat - A protocol for reserving bandwidth in an Ethernet network.
ieee 802.1Qav - Specifies how Ethernet packets marked with AVB QoS priority values are pro-
cessed
ieee 802.3 - The IEEE standards working group responsible for Ethernet cabling standards
ieTf - The Internet Engineering Task Force standardizes Internet Protocols.
LaN - A Local Area Network (LAN) is a network (often small) where devices can communicate
directly with all other devices.
QoS - Quality of Service. A variety of techniques used to ensure that some network traffic receives
preferential treatment from the network. For example, QoS ensures that Voice over IP telephone
calls are not interrupted by email traffic in a local network.
TCP/iP - Often refers to the full suite of Internet Protocols. The Transmission Control Protocol
(TCP) is also a specific protocol which provides reliable connections between devices. TCP is the
underlying network transport for the web.
UdP/iP - The User Datagram Protocol (UDP) provides a very efficient, message oriented encap-
sulation for data. It is well suited to real time applications and forms the basis for the Realtime
Transport Protocol (RTP).
Unicast -Point-to-point communication - packets travel along a path between the sender and re-
ceiver. Unicast avoids flooding packets throughout the network.
VLaN - Ethernet switches can create private LANs connecting one or more of their ports. VLANs
are isolated from each other. Some devices can be part of more than one VLAN at a time.
