DMH TCP/IP Stack and TCP Module
The TCP source-package is an optional extension module to the basic UDP/IP protocol stack. TCP is needed in system where TCP based applications are used. Typical TCP applications are Telnet Server, HTTP (web) Server and more.
TCP stands for Transmission Control Protocol. It provides reliable data transfer through a technique known as positive acknowledgment with retransmission. The technique requires the sender to communicate with the source, sending back an acknowledgment message as it receives data. The sender keeps a record of each packet it sends and waits for an acknowledgment before sending the next packet. The sender also starts a timer when it sends a packet, and retransmits a packet if the time expires before an acknowledgment protocol arrives. TCP uses the sliding window protocol for flow control and error control. TCP assumes IP is unreliable and provides 16-bit checksum of the entire message.
The protocol specifies how TCP software distinguishes among multiple destinations on a given machine. The protocol also specifies how two computers initiate a "TCP connection " and how they agree when it is complete.
Some of the TCP properties are:
