What is data network system?

A data network is a system designed to transfer data from one network access point to one other or more network access points via data switching, transmission lines, and system controls. Data networks consist of communication systems such as circuit switches, leased lines, and packet switching networks.

What are the types of data network?

Personal Area Network (PAN)

What are the three main types of data networks?

There are mainly three types of computer networks based on their size:

• Local Area Network (LAN)
• Metropolitan Area Network (MAN)
• Wide area network (WAN)

What is data communication and data networking?

Data communications refers to the transmission of this digital data between two or more computers and a computer network or data network is a telecommunications network that allows computers to exchange data.

What is data network name?

In 5G, Data Networks are specifically identified using a DNN. The DNN is typically in the form of an APN (Access Point Name).

What is APN and DNN?

Each is identified with a (human readable) name which in 2G, 3G and 4G networks was referred to as the APN (Access Point Name). In the 5G core, it is referred to as the DNN (Data Network Name). Furthermore, these rules can be used to enforce maximum data transmission speeds for certain traffic such as voice packets.

What is APN OI?

The value in the APN-OI-Replacement field is intended to replace the APN-OI (derived from the IMSI) during the GGSN selection process. The replacement results in the construction of a fully qualified domain name (FQDN) APN, for a preferred GGSN, to be used for DNS resolution.
