DARPA Internet Program. Internet and Transmission Control Specifications

摘要

These protocols are designed for use in an interconnected system of packet switched networks. The Internet Protocol is a basic universal protocol, and provides a uniform address space, as well as the mechanism for routing datagrams through the connected set of networks and for the fragmentation and reassembly of long datagrams if necessary for transmission through small packet networks. The Transmission Control Protocol is designed to be a highly reliable end-to-end data stream connection protocol between hosts, using mechanisms such as checksums, positive acknowledgements and timeouts with retransmission, and flow control.
