NetTester/1

NetTester/1's architecture is centered around its interaction with the z/OS operating system and VTAM. The main components include the NetTester/1 application itself, the VTAM interface, and the z/OS system services. The NetTester/1 application is the core component, providing the user interface and command processing capabilities.

The VTAM interface handles communication with the network, utilizing VTAM APIs to send and receive network traffic. The z/OS system services provide the underlying infrastructure for the application, including security, logging, and resource management. Communication between these components occurs through standard z/OS mechanisms, including system calls and inter-process communication.

NetTester/1 does not use any external databases or storage mechanisms for its primary functions; it relies on the z/OS environment for data persistence. The application uses standard VTAM ports for network communication. Configuration parameters are stored in z/OS datasets and are managed through the NetTester/1 interface.

The administrative interface is primarily a command-line interface (CLI), accessible through the z/OS console or a TSO session. User management is handled through RACF integration, ensuring that only authorized users can access and utilize the testing tools. The main configuration parameters include node names, test intervals, and logging levels.

Monitoring capabilities are provided through display commands and logging features, allowing administrators to monitor network status and test results in real-time. NetTester/1 supports RACF for authentication, ensuring secure access to its functions. Audit logging is provided to track user activities and system events.
