TCP

The Transmission Control Protocol (TCP) defined in standard protocols ensures high-reliability transmission between hosts. TCP provides reliable, connection-oriented, and full-duplex services for user processes. TCP transmits data through sequenced and nonstructural byte streams.

TCP is an end-to-end, connection-oriented, and reliable protocol. TCP supports multiple network applications. In addition, TCP assumes that the lower layer provides only unreliable datagram services, and it can run over a network of different hardware structures.

Figure 9-1 shows the position of TCP in a layered protocol architecture, where TCP is above IP. TCP can transmit variable-length data through IP encapsulation. IP then performs data fragmentation and assembly and transmits the data over multiple networks.

Figure 9-1 TCP in the layered protocol architecture

TCP works below applications and above IP. Its upper-layer interface consists of a series of calls similar to the interrupt call of an operating system.

TCP can asynchronously transmit data of upper-layer applications. The lower-layer interfaces are assumed as IP interfaces. To implement connection-oriented and reliable data transmission over unreliable networks, TCP must provide the following:

  • Reliability and flow control functions

  • Multiple interfaces for upper-layer applications

  • Data for multiple applications

  • Connection assurance

  • Communication security assurance

Figure 9-2 shows the process of setting up and tearing down a TCP connection.
