What is TCP connection establishment and tear down? The following is the process for TCP connection:
1. As connection is made by synchronizing sender and receiver and the OS is informed about the connection establishment.
2. Sender starts sending information and gets acknowledged. Soon after the sender sends the data, a timer is started.
3. When the sender is not received any acknowledgement ever after exceeding the timer’s limit, the data is transmitted.
4. If windowing occurs, buffer on the receiver is full, then a stop signal is sent by the sender and stops sending information
5. Soon after processing all data, a go signal is sent by the sender, followed by transmitting data again
