Latest Patents

Zhang's latest patents include the following innovations:

1. **Method and apparatus for managing data imaging in a distributed computer system**

This invention introduces a sophisticated three-tiered data imaging system. At the lowest tier, management facade software operates on each machine, transforming platform-dependent interfaces into platform-independent method calls. The middle tier consists of federated Java beans that communicate amongst themselves and with the management facades. The upper tier features user-friendly presentation programs enabling management personnel to easily control the system. This innovative architecture allows for centralized configuration of the entire data imaging system from a single location.

2. **Method and apparatus for managing remote data replication in a distributed computer system**

Similar in structure to his first patent, Zhang's data replication management system utilizes a three-tiered approach. The lowest tier includes management facade software that converts low-level kernel routines into platform-independent calls. Federated Java beans in the middle tier facilitate communication across the system, while the upper tier comprises interactive presentation programs for user management. Each host runs a data replication bean, which connects directly to a user-controlled management interface, providing efficient remote data management capabilities.
