Title: John H Hughes: Innovator in Networking Technologies

Introduction

John H Hughes is a prominent inventor based in San Jose, CA, known for his significant contributions to networking technologies. With a total of 10 patents, Hughes has developed innovative solutions that enhance the efficiency and performance of communication systems.

Latest Patents

Hughes's latest patents include a method for hardware TOS remapping based on source autonomous system identifier. This invention describes a rapid method and apparatus for remapping the type of service (TOS) and source address information from incoming communications packets. The goal is to ensure the desired Quality of Service (QoS) for communications flows into switches or routers. The method utilizes the input source address field of the packet header to access a lookup table of corresponding source autonomous system (AS) labels. This process optimizes intra-switch TOS for the appropriate QoS, facilitating efficient packet management and throughput.

Another notable patent is the hardware-based route cache using prefix length. This invention defines a system and method for routing packets using a hardware-based route cache. When a router receives a packet, it first searches for routing information in the hardware-based route cache. If a match is found, the packet is forwarded according to the routing information, enhancing the routing efficiency.
