PIE/CICS-NetMizer is an optional PIE/CICS component that reduces the size of 3270 data streams before they are sent across a network.
PIE/CICS-NetMizer uses a combination of data compression techniques and optimization methods to reduce the overall volume of network traffic. As a result, network congestion is reduced and the average transaction response time improves. Compressed data streams can be as much as 60% to 95% smaller than their original size. PIE/CICS-NetMizer also uses a variety of optimization methods that reduce the number of data streams required to sustain current screen images on user terminals.
PIE/CICS-NetGate provides VTAM access with significantly less performance overhead than a traditional VTAM session manager. Some savings are a result of PIE/CICS-NetGate’s more efficient VTAM connections, however, the greatest reduction in overhead comes from the partnership of MultiCICS and PIE/CICS-NetGate. Using both products together, VTAM resources are used only when a user is in a PIE/CICS-NetGate session; not continuously. If users spend 90% of their time in their standard MultiCICS sessions and only 10% in PIE/CICS-NetGate sessions, they incur only a 10% VTAM overhead.
Inbound suppression optimization formatted screens send only modified fields from the terminal to an application.
A modified field is indicated by two methods:
Applications mark modified fields to ensure they are returned from the terminal, whether the field is changed by a user or not. Usually, this is done to avoid the coding required to keep the fields in a commarea. There is a significant amount of network overhead to send unchanged modified fields back and forth between an application and a terminal.
PIE/CICS-NetMizer reduces the overhead of sending an inbound data stream from the terminal to an application. On the outbound data stream from the application to the terminal, PIE/CICS-NetMizer records the fields the application marked as modified. It then resets the fields to nonmodified and sends the data stream to the terminal. Users perform their processing and press an AID key to return the data stream. As always, only changed fields are returned over the network. PIE/CICS-NetMizer then intercepts the data stream. If any of the fields the application marked as modified are missing from the data stream, they are added back to the data stream and returned to the application.
Inbound suppression optimization results in the following:
The application receives all requested fields, but the network sends only the modified data.
