Title: Ho-Yen Chang: Inventor in Switching Network Technologies.

Introduction

Ho-Yen Chang is an inventor based in Cary, North Carolina. His patent work focuses on methods for routing data and balancing traffic in multi-stage switching networks. Chang is associated with Telefonaktiebolaget LM Ericsson (publ). His portfolio includes 2 patents.

Latest Patents

Chang’s listed patents address virtual circuit identification and path allocation in switching systems.

“Enhanced Virtual Circuit Allocation Methods and Systems for Multi-Stage Switching Elements” describes a system and method for routing data through a switching node made up of multiple switching elements and links. A virtual circuit identification algorithm determines a path-selection formula intended to distribute data traffic evenly through the node.

“Methods and System of Virtual Circuit Identification Based on Bit Permutation of Link Numbers for Multi-Stage Elements” presents a method for assigning paths through an interconnection network of switching elements and links. It uses the network’s physical restrictions to create a logical representation of its architecture, then considers traffic patterns to balance data across links. The resulting virtual channel identifiers determine paths through the network.

Career Highlights

Chang’s patents reflect a focus on network architecture, virtual circuits, and traffic distribution. The described techniques aim to improve how data paths are selected and how traffic is spread across switching elements and links.

Collaborations

Chang’s listed coworkers include Ritesh Ahuja and James Da Silva. His work is associated with Telefonaktiebolaget LM Ericsson (publ).

Conclusion

Ho-Yen Chang’s patent work centers on virtual circuit identification and balanced routing, with methods designed to distribute data traffic more evenly through multi-stage switching networks.
