management middleware

The Management Middleware is a database driven system for the configuration and management of embedded Linux/uClinux products. The software resides on the end-point node and manages system configuration changes. The system provides an API and set of tools that can be used to integrate with custom applications or used as provided. System services, interfaces and process are centralized into a database architecture accessible through various tools and a standard set/get API compatible with SNMP. Changes can be made to the database in real-time and are implemented in a controlled way through a configuration engine that processes change requests against it’s system of policies and dependencies. Changes are applied to the running system while preserving the quality-of-experience for the user and the robustness of the product.

Arcturus provides a complete suite of services to support the middleware including; porting, customization, application development, product development, support and training.
