Frank Pan

Title: Frank Pan and High-Availability Failover Technology.

Introduction

Frank Pan is an inventor associated with Burnaby, Canada, and Fortinet, Inc. His patent work addresses a reliability challenge in high-availability systems: split-brain conditions, in which primary and backup appliances may have conflicting views of which system should provide services.

Latest Patents

Pan is credited with 1 patent, titled “Use of Backup Heartbeat Signal to Mitigate Split-Brain Conditions.” The invention describes monitoring heartbeat packets received through a regular interface to assess the stability of the connection between primary and backup appliances. If the primary appliance appears to be operating improperly, the backup appliance enables a backup heartbeat interface and sends backup heartbeat packets to the primary appliance’s regular interface. The backup appliance then takes over the services previously provided by the primary appliance and continues transmitting backup heartbeat packets while doing so.

Career Highlights

Pan’s listed patent reflects work on fault detection and service continuity in high-availability systems. By using a backup heartbeat interface alongside the regular interface, the approach is designed to help identify primary-appliance failures and support a controlled transition to backup services.

Collaborations

Pan’s listed coworker is Jinshan Gu. The patent information provided identifies Fortinet, Inc. as Pan’s company.

Conclusion

Frank Pan’s patent focuses on using backup heartbeat signaling to detect and mitigate split-brain conditions, helping backup appliances maintain service continuity when a primary appliance is not operating properly.
