How to Configure TCP/IP Parameters

The TCP/IP (Transmission Control Protocol over Internet Protocol) is
divided into two areas. The Internet Protocol (IP) is used for the
fragmentation and addressing of data and transfers the data from
the sender to the recipient.

The Transmission Control Protocol (TCP) guarantees reliable and
in-order delivery of sender to receiver data. Upon receipt of one or
more packets, the receiver returns an acknowledgement.

The protocol forwards data packets across several connections and
establishs a connection between the network participants. The boot
protocols BOOTP, DHCP, and ZeroConf belong to the TCP/IP protocol
family. You can define various parameters for an ideal integration of
your TPG into a TCP/IP network.
