Title: Jean-François LePennec: Inventor in Isochronous ATM Ring Networks

Introduction

Jean-François LePennec is an inventor associated with Nice, France, and International Business Machines Corporation. His recorded patent work addresses real-time communication in ring networks using Asynchronous Transfer Mode (ATM) cells. He is credited with 1 patent.

Latest Patents

His listed patent, “Method and Apparatus for Allowing Communication in an Isochronous” (title as provided), describes a method for carrying isochronous ATM traffic through a ring network with multiple stations and a ring server. The system uses control cells to convey commands and parameters, while data cells carry payloads divided into slots shared among stations.

The ring server assigns transmission and reception identifiers linked to lists of allocated slots. The patent also describes pairs of registers that support real-time processing, memory storage, and the transparent transmission of unchanged or substituted bytes around the ring.

Career Highlights

LePennec’s documented invention focuses on coordinating time-sensitive data exchange across network stations. Its slot-allocation and cell-processing mechanisms are designed to support efficient transmission and reception within an ATM ring network.

Collaborations

The listed coworkers associated with LePennec are Francis E. Baudelot and Alain Benayoun. His company affiliation is International Business Machines Corporation.

Conclusion

Jean-François LePennec’s recorded patent highlights an approach to real-time ATM communication that combines shared data slots, server-managed identifiers, and register-based processing in a ring network.
