The network job receiver component, which receives jobs over the NJE lines, is similar to the input service processor. The network job receiver reads in jobs from other host nodes in a manner similar to the method used to read in jobs from RJE workstations. The difference is the network job receiver expects NJE protocols from the other host nodes and there are some changes to job processing. When the receiver detects a job destined for another node, it reads the job in to the spool without examining the data. The node then uses the network job transmitter to continue the job's journey to the ultimate destination.

When a node receives a job from the network, JES2 uses the header and trailer it receives from the network job transmitter. If the received job header or trailer does not contain all the sections necessary for JES2 processing, JES2 adds them to the headers received. The JES2 input service processor treats multiple jobs received in a single file as a single job. Sending multiple jobs through the network in a single file could cause unpredictable results; a job might execute at a node other than the one you intended.
