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 |
Multi-unicast |
A multi-unicast program (also known as multiple unicast) can transmit a single audio stream with common connection settings to a number of different destinations. |
MSN |
Multiple Subscriber Number for ISDN |
NAT |
Network Address Translation is a system for forwarding data packets to different private IP network addresses that reside behind a single public IP address. |
Packet |
A formatted unit of data carried over packet-switched networks. |
PAT |
Port Address Translation is 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 |

Plain old telephone system: copper phone network infrastructure |
PSTN |
Public switched telephone network which is another term for POTS (see previous) |
PSU |
Power Supply Unit |
QoS |
Quality of Service priority is 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 |
Runtime (edits) |
Configuration changes which have not yet been saved, e.g. Matrix Editor edits. |
SDP |
Session Description Protocol 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 |
SIM |
Subscriber Identity Module is an integrated circuit used to identify and authenticate subscribers on mobile cellular devices. |
SIP |
Session Initiation Protocol is a common protocol which works with a myriad of other protocols to establish connections with other devices to provide interoperability |

TCP |
Transmission Control Protocol ensures reliable in-order delivery of data packets between a sender and a receiver |
TLS |
Transport Layer Security is an updated version of SSL. |
TTL |
Time-to-Live is the setting used in multicast servers to ensure data packets have a finite life and don't cause congestion over networks |
UDP |
User Datagram Protocol: 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 |
Unicast |
Broadcasting of a single stream of data between two points |
