Title: Steven Lin and His Packet-Switch System Patent.

Introduction

Steven Lin is an inventor associated with Fremont, California, and PMC-Sierra, Inc. His work includes a patented packet-switch system designed to integrate linecards with a switch core.

Latest Patents

Lin is credited with 1 patent, titled “Packet-switch system.” The invention uses a linecard-to-switch (LCS) protocol to connect linecards with a switch core. Because the linecards handle most of the system’s buffering and are physically separate from the core, the design can reduce the size of the switch core.

The LCS protocol uses label swapping, credit-based flow control, and does not require the system to know details such as the number of port modules in the core or which quality-of-service and multicast flows are available. It also allows the linecards to manage most system buffers and control data-drop policies.

Career Highlights

Lin’s documented patent work focuses on network-switch architecture and the distribution of buffering and control functions between linecards and a switch core. The available information associates him with PMC-Sierra, Inc.

Collaborations

Lin’s listed coworkers include Anders Swahn and Balaji Satyanarayana Prabhakar. The available information does not specify their roles in developing the patent.

Conclusion

Steven Lin’s packet-switch system patent describes an approach to simplifying switch-core design by assigning substantial buffering and data-management responsibilities to linecards.
