RTP Real-time Transport Protocol defines a standardized packet format for delivering
audio and video over the Internet. It was developed by the Audio-Video Transport
Working Group of the IETF and first published in 1996 as RFC 1889
SDP Session Description Protocol is a format for describing streaming media
initialization parameters. It has been published by the IETF as RFC 2327.
SIP Session Initiation Protocol, An IP telephony signaling protocol developed by the
IETF (RFC3261). SIP is a text-based protocol suitable for integrated voice-data
applications. SIP is designed for voice transmission and uses fewer resources and is
considerably less complex than H.323.
STUN Simple Traversal of UDP over NATs is a network protocol allowing clients
behind NAT (or multiple NATs) to find out its public address, the type of NAT it is
behind and the internet side port associated by the NAT with a particular local port.
This information is used to set up UDP communication between two hosts that are
both behind NAT routers. The protocol is defined in RFC 3489. STUN will usually work
well with non-symmetric NAT routers.
TCP Transmission Control Protocol is one of the core protocols of the Internet
protocol suite. Using TCP, applications on networked hosts can create connections to
one another, over which they can exchange data or packets. The protocol guarantees
reliable and in-order delivery of sender to receiver data.
TFTP Trivial File Transfer Protocol is a very simple file transfer protocol, with the
functionality of a very basic form of FTP; it uses UDP (port 69) as its transport
protocol.
UDP User Datagram Protocol (UDP) is one of the core protocols of the Internet
protocol suite. Using UDP, programs on networked computers can send short
messages known as datagrams to one another. UDP does not provide the reliability
and ordering guarantees that TCP does; datagrams may arrive out of order or go
missing without notice. However, as a result, UDP is faster and more efficient for
many lightweight or time-sensitive purposes.
VAD Voice Activity Detection or Voice Activity Detector is an algorithm used in
speech processing wherein, the presence or absence of human speech is detected
from the audio samples.
VLAN A virtual LAN, known as a VLAN, is a logically-independent network. Several
VLANs can co-exist on a single physical switch. It is usually refer to the IEEE 802.1Q
tagging protocol.
VoIP Voice over the Internet. VoIP encompasses many protocols. All the protocols
do some form of signaling of call capabilities and transport of voice data from one
point to another. e.g.: SIP, H.323, etc.
