Product Overview

1 SNA Server's architecture is centered around several key components that facilitate SNA communication between UNIX and host systems. The SNA Stack is the core component, responsible for handling the SNA protocol implementation, including session management, data flow control, and error handling. The Logical Unit (LU) Manager is responsible for managing the logical units, which represent the endpoints of SNA sessions.

It handles the configuration and mapping of LUs to specific applications and resources on the host system. The Session Manager oversees the establishment, maintenance, and termination of SNA sessions between the client applications and the host. It coordinates the data exchange and ensures the integrity of the communication.

The Network Interface component handles the physical and data link layers of the network communication, managing the interaction with the underlying network infrastructure. Configuration data, including LU definitions, SNA parameters, and network settings, is stored in text-based configuration files. These files are parsed and loaded by the server during startup.

Logging and auditing are implemented using file-based mechanisms, capturing events, errors, and user activities for monitoring and troubleshooting. The server utilizes internal protocols for communication between its components, ensuring efficient and reliable operation. The server's design prioritizes modularity, allowing for easier maintenance and updates.

The server's components work together to provide a robust and scalable solution for SNA communication.
