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 les from a remote computer, Tel-
net allows you to log into and use a computer from a remote
location.
TFTP Trivial File Transfer Protocol
A protocol for le 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 cre-
ate separate sessions. Some applications, such as NetMeet-
ing, 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 connec-
tion. A trigger tells the device to expect these secondary ses-
sions 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 replace-
ment, and if so, whether to replace addresses on TCP pack-
ets only, UDP packets only, or both.
