Question

What is encapsulation in network protocols?

Answer 1

When referring to networking, encapsulation is the process of taking data from one protocol and translating it into another protocol, so the data can continue across a network. For example, a TCP/IP packet contained within an ATM frame is a form of encapsulation.

Answer 2

Answer:

The Basic concept of encapsulation says that data flows down the protocol hierarchy, headers (and trailers) get appended to it and data moves up the hierarchy headers (and trailers) get stripped off.

Example to illustrate :-

• Trivial file transfer protocol (TFTP).
• TFTP client transfer 200 bytes of data.
• 4 Bytes of TFTP header gets added.
