What is the practice of enveloping one protocol inside the header of another?

Answer 1

The technique of embedding one communication protocol within the header of a separate protocol is referred to as encapsulation. This process plays a pivotal role in facilitating data transmission across different network layers while ensuring seamless communication between devices. Encapsulation enables the integration of varying protocols, forming a harmonious and efficient data exchange environment.

In essence, encapsulation wraps the data from a higher layer protocol within the header of a lower layer protocol. This method allows data to traverse through different network layers, each contributing its own set of headers and trailers. The receiving end then decapsulates the data, removing headers and trailers sequentially to extract the original message.

Encapsulation is a fundamental component of networking models such as the OSI (Open Systems Interconnection) and TCP/IP (Transmission Control Protocol/internet Protocol). It promotes compatibility, modularity, and reliability in data communication, enabling various network devices and protocols to interact effectively.
