regarded as the primary standard for audio/video transport in IP networks and is used with an associated profile and
payload format.
Real Time Control Protocol (RTCP) is a sister protocol to the Real Time Transport Protocol, The primary function of
RTCP is to gather statistics on quality aspects of the media distribution during a session and transmit this data to the
session media source and other session participants
Session Initiation Protocol (SIP) is a signaling communications protocol, widely used for controlling multimedia
communication sessions such as voice over Internet Protocol (VOIP) networks. The protocol defines the messages
that are sent between endpoints which govern establishment, termination and other essential elements of a call. SIP
can be used for creating, modifying and terminating sessions consisting of one or several media streams.
Session Traversal Utilities for NAT (STUN) is a standardized set of methods and a network protocol to allow an end
host to discover its public IP address if it is located behind a NAT. It is used to permit NAT traversal for applications
of real-time voice messaging, and other interactive IP communications.
Transmission Control Protocol (TCP) is one of the core protocols of the Internet protocol (IP), and is so common
that the entire suite is often called TCP/IP. TCP provides reliable, ordered and error-checked delivery of a stream of
octets (data packets) between programs running on devices connected to a local area network (LAN), intranet or the
public Internet.
Voice over Internet Protocol (VoIP) is a methodology and group of technologies for the delivery of voice
communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet.
User Datagram Protocol (UDP) is one of the core members of the Internet protocol suite (the set of network
protocols used for the Internet). With UDP, device applications can send messages, in this case referred to as
datagrams, to other hosts on an Internet Protocol (IP) network without prior communications to set up special
transmission channels or data paths.
Wireless gateway is a computer networking device that routes packets from a wireless LAN to another network,
typically a wired WAN. Wireless gateways combine the functions of a wireless access point, a router, and often
provide firewall functions as well; thus they are converged devices.
