TCP
SVP
SpectraLink Voice Priority (SVP) is a QoS approach to Wi-Fi deployments. SVP is an open
specification that is compliant with the IEEE 802.11b standard. SVP minimizes delay and
prioritizes voice packets over data packets on the Wireless LAN, thus increasing the
probability of better network performance.

TCP
The Transmission Control Protocol (TCP) is built on top of Internet Protocol ( IP ). It adds
reliable communication (guarantees delivery of data), flow-control, multiplexing (more than
one simultaneous connection), and connection-oriented transmission (requires the receiver
of a packet to acknowledge receipt to the sender). It also guarantees that packets will be
delivered in the same order in which they were sent.
TCP/IP
The Internet and most local area networks are defined by a group of protocols. The most
important of these is the
Transmission Control Protocol over Internet Protocol (TCP/IP),
the de facto standard protocols. TCP/IP was originally developed by Defense Advanced
Research Projects Agency (DARPA, also known as ARPA, an agency of the US Department
of Defense).
Although TCP and IP are two specific protocols, TCP/IP is often used to refer to the entire
protocol suite based upon these, including ICMP, ARP, UDP , and others, as well as
applications that run upon these protocols, such as telnet, FTP, etc.
TKIP
The Temporal Key Integrity Protocol (TKIP) provides an extended 48-bit initialization
vector, per-packet key construction and distribution, a Message Integrity Code (MIC,
sometimes called “Michael”), and a re-keying mechanism. It uses a
RC4 stream cipher to
encrypt the frame body and CRC of each 802.11 frame before transmission. It is an
important component of the WPA and 802.11h security mechanisms.
