TCP/IP Transmission Control Protocol/Internet Protocol
The basic protocols used on the Internet. TCP is responsible for
dividing data up into packets for delivery and reassembling them at the
destination, while IP is responsible for delivering the packets from
source to destination. When TCP and IP are bundled with higher-level
applications such as HTTP, FTP, Telnet, etc., TCP/IP refers to this
whole suite of protocols.
Telnet An interactive, character-based program used to access a remote
computer. While HTTP (the web protocol) and FTP only allow you to
download files from a remote computer, Telnet allows you to log into
and use a computer from a remote location.
TFTP Trivial File Transfer Protocol
A protocol for file transfers, TFTP is easier to use than File Transfer
Protocol (FTP) but not as capable or secure.
TKIP Temporal Key Integrity Protocol (TKIP) provides WPA with a data
encryption function. It ensures that a unique master key is generated for
each packet, supports message integrity and sequencing rules and
supports re-keying mechanisms.
triggers Triggers are used to deal with application protocols that create separate
sessions. Some applications, such as NetMeeting, open secondary
connections during normal operations, for example, a connection to a
server is established using one port, but data transfers are performed on a
separate connection. A trigger tells the device to expect these secondary
sessions and how to handle them.
Once you set a trigger, the embedded IP address of each incoming packet
is replaced by the correct host address so that NAT can translate packets
to the correct destination. You can specify whether you want to carry out
address replacement, and if so, whether to replace addresses on TCP
packets only, UDP packets only, or both.
twisted pair The ordinary copper telephone wiring used by telephone companies. It
contains one or more wire pairs twisted together to reduce inductance
and noise. Each telephone line uses one pair. In homes, it is most often
installed with two pairs. For Ethernet LANs, a higher grade called
Category 3 (CAT 3) is used for 10BASE-T networks, and an even
higher grade called Category 5 (CAT 5) is used for 100BASE-T
networks. See 10BASE-T, 100BASE-T, Ethernet.
unnumbered interfaces An unnumbered interface is an IP interface that does not have a local
subnet associated with it. Instead, it uses a router-id that serves as the
source and destination address of packets sent to and from the router.
Unlike the IP address of a normal interface, the router-id of an
unnumbered interface is allowed to be the same as the IP address of
another interface. For example, the WAN unnumbered interface of
your device uses the same IP address of the LAN interface
The unnumbered interface is temporary – PPP or DHCP will assign a
‘real’ IP address automatically.
upstream The direction of data transmission from the user to the Internet.
VC Virtual Circuit
A connection from your DSL router to your ISP.
VCI Virtual Circuit Identifier
Together with the Virtual Path Identifier (VPI), the VCI uniquely
identifies a VC. Your ISP will tell you the VCI for each VC they provide.
VPI Virtual Path Identifier
Together with the Virtual Circuit Identifier (VCI), the VPI uniquely
