Title: Innovations by Chien-En Sun

Introduction

Chien-En Sun is an accomplished inventor based in Chapel Hill, NC (US). He has made significant contributions to the field of network security, holding a total of 2 patents. His work focuses on techniques to defend against network flooding attacks, which are critical in maintaining server integrity and performance.

Latest Patents

Chien-En Sun's latest patents include a "Technique of defending against network flooding attacks using a connectionless protocol." This invention prevents server overload and potential crippling due to a flooding of connectionless datagrams, whether from intentional attacks or other causes. The method involves determining the number of datagrams already queued to a specified port from a host. If this number exceeds a first threshold, the datagram is discarded. The threshold is calculated by multiplying a percentage P by the number of available queue slots remaining for the port.

Another notable patent is the "Technique of defending against network connection flooding attacks." This invention also aims to prevent server overload and possible crippling due to a flooding of connection requests. In this case, the number of connections assigned to a host for a specified port is determined. If this number exceeds a first threshold, the connection request is denied. However, an override is possible if a quality of service parameter allows it. If the number of available connections to the port is below a second threshold, the request is denied regardless.
