Transmission Control Protocol – Transport layer protocol




In this article we will discuss Transmission Control Protocol – Transport layer protocol, will make brief discussion on Transmission Control Protocol. In last article we discuss about Transport Layer Reliability.



Transmission Control Protocol

TCP transport is analogous to sending packages that are tracked from source to destination. If a shipping order is broken up into several packages, a customer can check online to see the order of the delivery. TCP is one of the main protocols in TCP/IP networks. Whereas the IP protocol deals only with packets, TCP enables two hosts to establish a connection and exchange streams of data. TCP works with the Internet Protocol (IP), which defines how computers send packets of data to each other.

The Transmission Control Protocol/Internet Protocol, is a suite of communication protocols used to interconnect network devices on the internet. The Defense Data Network, part of the Department of Defense, developed TCP/IP, and it has been widely adopted as a networking standard. TCP (Transmission Control Protocol) is a standard that defines how to establish and maintain a network conversation via which application programs can exchange data. TCP works with the Internet Protocol (IP), which defines how computers send packets of data to each other.



TCP guarantees delivery of data and also guarantees that packets will be delivered in the same order in which they were sent. With TCP, there are three basic operations of reliability:

  • Numbering and tracking data segments transmitted to a specific host from a specific application
  • Acknowledging received data
  • Retransmitting any unacknowledged data after a certain period of time
