Introduction to Network Job Entry (NJE)

An NJE network is a group of two or more complexes or systems that communicate with each other. An NJE network is comprised of nodes that can transmit or receive a unit of work. The nodes in an NJE network use protocols to communicate with each other. Protocols are rules a node uses to:

Become part of an NJE network
Receive a unit of work
Send a unit of work
Indicate it was removed from the network.

For an illustration of an NJE network, see Figure 1.
