Editing Packet radio (section)

=== Network ===

Packet radio has most often been used for direct, keyboard-to-keyboard connections between stations, either between two live operators or between an operator and a [[bulletin board system]]. No network services above the data link layer are required for these applications.

To provide automated routing of data between stations (important for the delivery of [[electronic mail]]), several network layer protocols have been developed for use with AX.25. Most prominent among these network layer protocols are NET/ROM & TheNET, ROSE, FlexNet and TexNet.

In principle, any network layer protocol may be used, including the ubiquitous [[Internet Protocol]].
