Title: Chih-Mei Lin: Innovator in Packet Routing Technologies
Introduction
Chih-Mei Lin is a notable inventor based in Parsippany, NJ (US), recognized for his contributions to the field of packet routing technologies. With a total of 4 patents, Lin has made significant advancements in managing quality of service in distributed networks.
Latest Patents
Lin's latest patents include innovative methods for packet routing via payload inspection. One of his key inventions focuses on packet routing at routers in a core of a distributed network, which is designed to distribute content according to quality of service guarantees. This method involves packets containing subjects and attributes alongside routing information. The subjects correspond to specific types of content for subscriptions, while the attributes encapsulate the data or content. The routers utilize filters that correspond to subscriptions, inspecting the payload section of packets to match attributes to these filters. If the attributes satisfy a filter, the packet is routed accordingly. Conversely, if no filters are satisfied, the router discards the packet. This distributed decision-making enhances the efficiency of routing in the network core.
Another significant patent by Lin is the method and apparatus for content-based routing and filtering at routers using channels. This invention establishes logical connections between routers, allowing for packet routing through defined subjects and attributes. Publishers can create channels for routing specific types of content, and routers apply packet attributes to filters encapsulating subscriptions to perform content-based routing. This innovation also includes local caching of content, which provides distributed caching throughout the network core.
Career Highlights
Throughout his career, Lin has worked with several prominent companies, including Precache, Inc. and AT&T Corp. His experience in these organizations has contributed to his expertise in network technologies and packet routing.
Collaborations
Lin has collaborated with notable professionals in the field, including Yennun Huang and Shalini Yajnik, who is recognized for her contributions as a woman in technology.
Conclusion
Chih-Mei Lin's innovative work in packet routing technologies has significantly impacted the way content is managed and distributed in networks. His patents reflect a deep understanding of quality of service management, showcasing his role as a leading inventor in this domain.
