Title: R. Douglas Howson: Telecommunications Protection-Switching Inventor.

Introduction

R. Douglas Howson is an inventor associated with telecommunications technology and patents. His work includes methods and systems designed to maintain network service when components or traffic paths fail. He is associated with Santa Rosa, California, and holds 3 patents.

Latest Patents

Howson’s listed patents address protection switching and transport interfaces in telecommunications networks.

“Method and System for Protection Switching in a Telecommunications Network” describes a method that receives primary and secondary sub-streams, with each primary sub-stream corresponding to a redundant secondary sub-stream. The system assigns priority levels to the sub-streams and uses those priorities to guide protection switching.

“Transport Interface for Performing Protection Switching of Telecommunications Traffic” describes a transport interface that supports add-drop multiplexing and network-traffic termination. It uses redundant high-speed units, broadband interfaces, and SONET formatters connected through in-band and protection-pair data links. These links coordinate switching between components when a failure occurs, helping the interface transition smoothly to a protected component.

Career Highlights

Howson’s career includes work associated with DSC Communications Corporation and Alcatel USA. His patent work reflects a focus on telecommunications infrastructure, including network reliability and continuity of service.

Collaborations

His listed coworkers include Thomas A. Potter and Martin Roberts. The patent descriptions also reflect the coordinated operation of multiple interface components and protection mechanisms.

Conclusion

R. Douglas Howson’s patents address practical ways to preserve telecommunications service through redundant components and priority-based protection switching.
