Title: Yucheng Ye and Protection Switching in Packet-Based Networks.

Introduction

Yucheng Ye is an inventor associated with Ottawa, Canada, and Nortel Networks Corporation. His patent work addresses protection switching in packet-based telecommunications systems, including asynchronous transfer mode (ATM) networks.

Latest Patents

The available information identifies one patent associated with Ye: “Protection Switching Trigger Generation.” The invention concerns a system with a main data path and bypass paths that protect designated portions of the network. Nodes monitor these protection domains and send alarm packets downstream with identifiers indicating where each alarm originated. A receiving node uses the identifier to decide whether rerouting is needed, helping prevent unnecessary protection switching when an upstream node has already activated a bypass. This approach aims to avoid the added complexity, cost, and delay of extracting and modifying alarm packets at intermediate nodes. Ye is credited with 1 patent.

Career Highlights

Ye’s listed work connects him with Nortel Networks Corporation and focuses on network reliability and efficient fault response. The patent describes a way to coordinate protection switching across network nodes while limiting redundant rerouting actions.

Collaborations

The provided information lists Khalid Ahmad and David Wright Martin as Ye’s coworkers. It does not specify their roles in the patent or the extent of their collaboration.

Conclusion

Yucheng Ye’s identified patent presents a method for using alarm-origin identifiers to make protection switching in packet-based networks more efficient and avoid unnecessary rerouting.
