What is IMS Network Compression Facility for z/OS?
Reduce traffic across networks
Reduce the amount of data transferred from IMS to user devices with support for all forms of output to 3270 devices using standard 3270 data stream protocol.
Decrease process redundancies
Use new options for compression of 3270 data streams and repeated characters (not only spaces, nulls, asterisks and dashes) to eliminate redundant 3270 Set Buffer Address (SBA) commands.
Improve work process flexibility
Use cross-MVS system inquiries and updates to Network Compression Facility information and options, and dynamically change options via its ISPF interface.
