Title: Innovations by John D. Kari

Introduction

John D. Kari is a notable inventor based in Coeur d'Alene, ID (US). He has made significant contributions to the field of technology, particularly in the area of virtual private networks (VPNs). With a total of 6 patents to his name, Kari's work focuses on enhancing network efficiency and power conservation.

Latest Patents

One of Kari's latest patents involves using a transmission control protocol (TCP) channel to save power for virtual private networks (VPNs) that utilize user datagram protocol (UDP). This innovative method allows for maintaining a VPN connection between a mobile device and a server over a wireless network while conserving the mobile device's power supply. The process is particularly effective for connections that require server-initiated traffic. After a successful login to a VPN server, a VPN client establishes both a TCP and a UDP connection with the server. If a power timeout occurs, the server calculates the elapsed time since the last tunnel traffic. If this time exceeds a predetermined power timeout value, the VPN server sends a control message to the client via the TCP channel, prompting the client to reestablish the UDP connection and resume transmission.

Another significant patent by Kari is focused on dynamic network tunnel endpoint selection. This invention allows a client to dynamically select a gateway as a tunnel endpoint for connecting over a public or untrusted network into an enterprise computing infrastructure. The selection process is based on least-cost routing metrics, which consider various factors such as proximity to the destination host, network stability, monetary costs, congestion, hop count, and latency.
