Latest Patents

**VPN Tunnel Redirection.** This invention redirects a VPN tunnel initiator or network source to a recommended tunnel terminator when traffic load, resource availability, or system reliability calls for a change. The terminator sends a special call-clear message containing the recommended terminator’s IP address. The initiator then establishes a session with that destination and resumes processing without ending the incoming call.

**Management of Polling Traffic in Connection-Oriented Protocol Sessions.** This invention reduces polling traffic used to maintain connection-oriented sessions across a shared link between network edge devices. Each edge device selects a polling session and blocks polling traffic from the other sessions, while the selected session helps maintain the connections. The polling session can rotate among the connections, preferably in round-robin order, so each is used in turn.

Career Highlights

Pereira’s listed inventions address practical challenges in network reliability and efficiency. VPN tunnel redirection supports continuity when network conditions change, while polling-traffic management helps reduce unnecessary traffic across shared links. His work is associated with 3Com Corporation.

Collaborations

Pereira’s listed coworkers include Joseph Tsyr-Shya Sun and Luis A. Daly.

Conclusion

Frank R. Pereira’s patents reflect a focus on improving the reliability and efficiency of network communications through VPN redirection and streamlined session maintenance.
