COMPUTER NETWORKING

Detailed explanation-1: -The encapsulated information is removed from the received data to obtain the original data. This process takes place at the receiver’s end. The data is de-encapsulated at the same layer at the receiver’s end to the encapsulated layer at the sender’s end.

Detailed explanation-2: -Transport Layer–Data Encapsulation Begins When the data arrives at the transport layer, the protocols at the layer start the process of data encapsulation. The end result depends on whether TCP or UDP has handled the information.

Detailed explanation-3: -De-encapsulation is the process used by a receiving device to remove one or more of the protocol headers. The data is de-encapsulated as it moves up the stack toward the end-user application.

Detailed explanation-4: -Outbound packets are rebuilt with additional IPSec headers in a process known as encapsulation, while inbound packets are stripped of their IPSec headers in a process known as decapsulation. Before leaving a host, outbound packets are encapsulated using a cryptographic key that is known to both communicating hosts.
