TCP is a portable implementation of the industry-standard TCP based on RFC 793. The software consists of the core TCP protocol, a library that provides a SLI to support IPv4. Applications and TELNET Server and FTP server that support IPv4 based connections (optional). TCP interacts with the network layer protocols and uses their services for end-to-end communication.
