Networking terms and abbreviations
Transmission Control Protocol. TCP, together with IP (Internet
Protocol), is the basic communication language or protocol of the
Internet. Transmission Control Protocol manages the assembling of a
message or file into smaller packets that are transmitted over the
Internet and received by a TCP layer that reassembles the packets into
the original message. Internet Protocol handles the address part of
each packet so that it gets to the right destination.
TCP/IP uses the client/server model of communication in which a
computer user (a client) requests and is provided a service (such as
sending a Web page) by another computer (a server) in the network.
Trivial File Transfer Protocol. An Internet software utility for transferring
files that is simpler to use than the File Transfer Protocol (FTP) but less
capable. It is used where user authentication and directory visibility
are not required. TFTP uses the User Datagram Protocol (UDP) rather
than the Transmission Control Protocol (TCP). TFTP is described
formally in Request for Comments (RFC) 1350.
Temporal Key Integrity Protocol (TKIP) is an enhancement to the WEP
encryption technique that uses a set of algorithms that rotates the
session keys. TKIP's enhanced encryption includes a per-packet key
mixing function, a message integrity check (MIC), an extended
initialization vector (IV) with sequencing rules, and a re-keying
mechanism. The encryption keys are changed (rekeyed) automatically
and authenticated between devices after the rekey interval (either a
specified period of time, or after a specified number of packets has
been transmitted).
Transport Layer Security. (See EAP, Extensible Authentication
ToS (Type of Service) / DSCP (Diffserv Codepoint). The ToS/DSCP
field contained in the IP header of a frame is used by applications to
indicate the priority and Quality of Service (QoS) for each frame. The
level of service is determined by a set of service parameters which
provide a three way trade-off between low-delay, high-reliability, and
high-throughput. The use of service parameters may increase the cost
of service.
Transition Security Network. A subset of Robust Security Network
(RSN), which provides an enhanced security solution for legacy
hardware. The Wi-Fi Alliance has adopted a solution called Wireless
Protected Access (WPA), based on TSN. RSN and TSN both specify
IEEE 802.1x authentication with Extensible Authentication Protocol
