Latest Patents

**Cache Memory Structure and Method.** This invention describes a cache memory and a method for controlling access to stored data. It uses a control area, advantageously separate from the data area, to manage access by application processes. The control area includes at least one release area with offsets and sections defining data versions. The invention is applicable to shared memories in client/server architectures.

**Method and System to Maintain Strong Consistency of Distributed Replicated Contents in a Client/Server System.** This invention addresses consistency among replicated files distributed across independent processing nodes in a multi-tier client/server system. When an update to the master database is requested, a new file version is generated and stored in a shared file system. The system notifies the participating nodes, which preload the new version and acknowledge completion. Once all acknowledgments are received, the master server is notified and updates the master database.

Career Highlights

Touffait’s listed inventions focus on coordinating access to cached data and synchronizing replicated files across distributed systems. These approaches address data availability and consistency in client/server environments.

Collaborations

His listed coworkers include Virginie Amar and Luc Capanaccia. His association with Amadeus S.A.S. provides professional context for his patent work.

Conclusion

Guillaume Touffait’s two patents concern practical methods for managing shared cache data and maintaining strong consistency across distributed, replicated files.
