The network layer routes the packet through the larger network. In many cases, the first hop across the local network, which the data link layer handles, takes the packet to a system with a router. The packet requires an internet address to address the destination system across the larger n...

in the tcp/ip (transmission control protocol/internet protocol) model, encapsulation involves four layers: application, transport, internet, and network access. each layer adds its own headers as data moves down. the osi model, however, has seven layers, providing more detailed encapsulation steps....
Since the OSI model has 7 layers, PDUs are numbered from 1 to 7, with the Physical layer being the first one. For example, the term Layer 3 PDU refers to the data encapsulated at the Network layer of the OSI model. Here is a graphical representation of all the PDUs in the OSI ...
functions in the network are abstracted from their underlying structures by inclusion or information hiding within higher level objects.The physical layer is responsible for physical transmission of the data. Link encapsulation allows local area networking and IP provides global addressing of individual ...
A capsule is a collection of neurons which represents different variants of a pattern in the network. The routing scheme ensures only certain capsules which resemble lower counterparts in the higher layer should be activated. However, the computational complexity becomes a bottleneck for scaling up ...
An Layer 2 sub-interface has been created using the interface interface-type interface-number.subnum mode l2 command in the system view. Precautions Each Layer 2 sub-interface can have only one encapsulation type configured. Before changing an encapsulation type, run the undo encapsulation co...
Encapsulation in networking refers to the inclusion of one data structure within another so the first is hidden until it has been decapsulated. It is key to both the TCP/IP and OSI networking models. The three top layers in the OSI model correspond to the application layer in TCP/IP. The...
As the data moves up from the lower layer to the upper layer of TCP/IP protocol stack (incoming transmission), each layer unpacks the corresponding header and uses the information contained in the header to deliver the packet to the exact network application waiting for the data. TCP/IP ...
in the header of each packet. If the packet is not intended for it, it will discard the packet. If the packet is intended for it, it will remove the header. Once the network layer’s header is removed, the packet becomes the segment. Segments are handed over to the Transport layer. ...
