Title: Ken Benstead: Innovator in PNNI Network Technologies

Introduction

Ken Benstead is a notable inventor based in Shrewsbury, MA (US). He has made significant contributions to the field of networking technologies, particularly in Asynchronous Transfer Mode (ATM) networks. With a total of 3 patents to his name, his work has had a lasting impact on the industry.

Latest Patents

One of Ken's latest patents is titled "Method of local flow control in an asynchronous transfer mode network utilizing PNNI routing protocol." This invention addresses flow control in PNNI networks by allowing congested nodes to communicate their status to the network. By advertising a PTSE with both Maximum Cell Rate (MCR) and Available Cell Rate (ACR) set to zero, the method prevents additional call requests from being processed during periods of congestion. Once the congestion subsides, the node can resume normal operations by advertising the original MCR and ACR values.

Another significant patent is "Apparatus for and method of testing a hierarchical PNNI based ATM network." This invention provides a means for debugging and testing complex multilevel PNNI-based ATM networks. It allows for the simulation of virtual portions of ATM networks that may be challenging to implement physically. The method involves generating an injection file containing PTSEs and injecting this file into the node under test, facilitating thorough testing and validation of network functionality.
