5 Glossary of Terms
AES3 Official term for the audio standard referred to often as AES/EBU
AES67 A technical standard for audio over IP and audio over Ethernet (AoE)
interoperability developed by the AES. It is a layer 3 protocol suite facilitating
interoperability between IP-based audio networking systems such as
WheatNet-IP, RAVENNA, Livewire, and Dante.
AES/EBU Digital audio standard used to carry digital audio signals between devices
CCC Cloud Codec Controller
CSRF Cross-Site Request Forgery (CSRF) is an attack that forces a user to execute
unwanted actions on a web application in which they are currently
authenticated.
Destinations An AoIP Destination in the codec is an AES67 stream received by the codec
from an AES67 LAN.
DNS The Domain Name System (DNS) is used to assign domain names to IP
addresses over the World-Wide Web
Domain A group of computers or devices on a network which are administered with
common rules and procedures. Devices sharing a common part of the IP
address are said to be in the same domain
DSCP The Differentiated Services Code Point or Diffserv Value is a field in an IP
packet header for prioritizing data when traversing IP networks. This is often
used in AES67 streaming.
Failover Method of switching to an alternative backup Audio Stream if the primary
connection is lost.
GUI Graphical User Interface
IFB Interrupted Foldback/Interruptible Foldback: an intercom circuit consisting of a
mix-minus program feed sent to talent, which can be interrupted and replaced
by a producer's or director's intercom microphone
IGMP A communications protocol used by hosts and adjacent routers on IPv4
networks to establish multicast group memberships to IPv4 routers.
IGMP snooping The process of listening to IGMP network traffic for delivery of IP multicasts.
Network switches with IGMP snooping maintain a map of which links need which
IP multicast transmission. Multicasts may be filtered to conserve bandwidth on
links.
ISP Internet Service Providers (ISPs) are companies that offer customers access to
the internet
IP Internet Protocol; used for sending data across packet-switched networks
IPv4 Internet Protocol version 4 is the most widely deployed version of the protocol
and is widely used on the Internet and on local area networks
IPv6 Internet Protocol version 6 is the most recent revision of the Internet Protocol
and is intended to replace IPv4 eventually.
LAN Local Area Network; a group of computers and associated devices sharing a
common communications link
Latency Delay associated with IP networks and caused by algorithmic, transport and
buffering delays
LIO Logic Input/Output
MIB A management information base (MIB) is a database used for managing the
entities in a communications network. This term is associated with the Simple
Network Management Protocol (SNMP).
Multicast Efficient one to many streaming of IP audio using multicast IP addressing.
