Title: Innovations of Hans Frederick Johnsen

Introduction

Hans Frederick Johnsen is a notable inventor based in Kanata, Canada. He has made significant contributions to the field of network technology, holding 2 patents that showcase his innovative approach to measuring network performance and resource allocation.

Latest Patents

One of his latest patents is titled "Method and system of measuring latency and packet loss in a network by using probe packets." This invention provides a method that involves inserting probe packets on a per-service basis for transmission on a respective round trip. For each service, the probe packets are used to calculate packet latency, which is representative of packet latency for all packets transmitted for that service. In some embodiments, data plane time stamps are utilized to accurately time probe latency. Additionally, the invention includes a method for inserting probe packets on a per-service basis for transmission to a respective destination network element. At the destination network element, the probe packets are used to calculate one-way packet loss for the service.

Another significant patent is "Network resource allocation methods and systems." This invention provides methods and components that ensure improved use of network resources while maintaining adequate performance of best effort (BE) traffic. It intelligently distributes BE traffic demands at the connection level with corresponding scaling weights, without reserving bandwidth. A weighted sum of the BE class connections in a link is used as a path selection criterion, where each BE connection is weighted by its service volume. Path selection for a requested BE service volume is performed by creating a virtual topology in which all links in a network have weighted BE metrics updated to include the effects of the requested BE service volume.
