Random information on the term “EARN”:

The European Academic and Research Network (EARN) was a computer network connecting universities and research institutions across Europe, and was connected in 1983 via transatlantic circuits and a gateway funded by IBM to BITNET, its peer in the United States.

Services available on EARN/BITNET included electronic mail, file transfer, real-time terminal messages, and access to EARN server machines which provided information retrieval services. Gateways existed from EARN to the ARPA Internet (ARPANET, MILNET, NSFNET, CSNET, X25Net), CSNET, UUCP, JANET (Great Britain’s Joint Academic Network), and more than 10 other national academic and research networks. There also was limited access to VNET, IBM’s internal communications network.

At the network layer EARN was based on a “store-and-forward” technology. In a “store-and-forward” network information is sent to an intermediate node where it is kept and sent as soon as possible to the next node on the path to its final destination. The intermediate node verifies the integrity of the message before forwarding it. Each time the intermediate node confirms the receipt of the data the originating node deletes it. The EARN “store-and-forward” system was originally based on IBM’s technology and used the Remote Spooling Communications Subsystem (RSCS) and NJE/NJI protocols on the IBM Virtual Machine (VM) mainframe operating systems, and JES2 (and later JES3, Job Entry Subsystem) on IBM MVS mainframe operating systems.
