Unicast
Digital audio standard used to carry digital audio signals between devices.
Official term for the audio standard referred to often as AES/EBU.
The Domain Name System (DNS) is used to assign domain names to IP
addresses over the World-Wide Web.
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.
The Differentiated Services Code Point is a field in an IP packet header for
prioritising data when traversing IP networks
Method of switching to an alternative audio stream if the primary connection is
lost.
Graphical User Interface
Internet Service Providers (ISPs) are companies that offer customers access to
the internet
Internet Protocol; used for sending data across packet-switched networks.
Delay associated with IP networks and caused by algorithmic, transport and
buffering delays.
Efficient one to many streaming of IP audio using multicast IP addressing.
A system for forwarding data packets to different private IP network addresses
that reside behind a single public IP address.
Related to NAT; a feature of a network device that allows IP packets to be
routed to specific ports of devices communicating between public and private
IP networks.
Power Supply Unit
Priority given to different users or data flows across managed IP networks. This
generally requires a Service Level Agreement (SLA) with a Telco or ISP.
A standardized packet format for sending audio and video data streams and
ensures consistency in the delivery order of voice data packets.
SDP defines the type of audio coding used within an RTP media stream. It
works with a number of other protocols to establishes a device's location,
determines its availability, negotiates call features and participants and adjusts
session management features.
SIP is a common protocol which works with a myriad of other protocols to
establish connections with other devices to provide interoperability.
Service Level Agreements (SLAs) a contractual agreement between an ISP
and a customer defining expected performance levels over a network
Simple Network Management Protocol
Studio to transmitter link for program audio feeds.
Studio to studio audio link
TCP protocol ensures reliable in-order delivery of data packets between a
sender and a receiver.
The most commonly used protocol for sending internet audio and video
streams. UDP packets include information which allows them to travel
independently of previous or future packets in a data stream.
Broadcasting of a single stream of data between two points.
