2.4 Data Encapsulation

What are the TCP/IP de-encapsulation process steps?

Data Encapsulation and the TCP/IP Protocol Stack. ... As the packet travels through the TCP/IP protocol stack, the protocols at each layer either add or remove fields from the basic header. When a protocol on the sending host adds data to the packet header, the process is called data encapsulation.

What are the TCP/IP encapsulation process steps on a sending host?

Data Encapsulation and the TCP/IP Protocol Stack. ... As the packet travels through the TCP/IP protocol stack, the protocols at each layer either add or remove fields from the basic header.

What is a PDU? How do PDUs relate to TCP/IP layers?

It transmits messages called segments that contain data encapsulated from higher-layer protocols. The layer below TCP is the Internet Protocol (IP) at layer 3. It receives data from TCP and encapsulates it for transmission. So, in the formal language of the OSI Reference Model, TCP segments are created as layer 4 PDUs.

What information does the Transport layer add to data being transmitted?

The transport layer is the layer in the open system interconnection (OSI) model responsible for end-to-end communication over a network. It provides logical communication between application processes running on different hosts within a layered architecture of protocols and other network components.

How does data encapsulation facilitate data transmission?

the term Layer 3 PDU refers to the data encapsulated at the Network layer of the OSI model.
