Data encapsulation is set o process is used or process for data transport in the network traffic. And as per typical packet some contains around 1,000 or 1,500 bytes.
Explanation:
In the network, there are 7 layers. Data will be processed are sent through these 7 layers. So to process and do validation checking necessary process is handled in each layer
For example, check valid TCPIP addresses on both ends such as source and designation.
Encapsulation on the network depends on the following things. Session layers, presentation layer, and application layers and converts the message to valid data and finally sent to the transport layer and data is converted to network layers.
