In information technologies, this process is called encapsulation, reminiscent of medical capsules. Data that is part of a packet has a payload, which is equal to plus one to the number of the packet.


In networking, this approach allows creating levels of information that users within an abstraction may view selectively, based on their assigned status that is related to these payloads. Unlike encapsulation within layers of OSI models, the single mechanism takes into consideration the internal structure of a system, which helps PPP frames to have fewer errors during data transmission.

However, Python, Java, and C++ languages can override these methods of hiding information with appropriate programming code. Thus, the transferred through VLAN-ccc units of data are therefore more available to various users, but retain a higher degree of accuracy.
