Title: Jacob Harrison Fitzharris: Inventor in Network Communications
Introduction
Jacob Harrison Fitzharris is an inventor associated with Johnson City, Tennessee. His patent work addresses multicast networking, including techniques for carrying Protocol Independent Multicast (PIM) messages across a Layer-3 transport network.
Latest Patents
Fitzharris is credited with 1 patent: “Protocol Independent Multicast (PIM) Across Transport Network.” The invention describes a first network device receiving a multicast packet over a Layer-2 network and generating a unicast Layer-3 packet containing a PIM register request. The request is configured to register the first device as a multicast source for a group associated with a multicast service.
The packet header specifies a source address that uses network address translation to point to a virtual loopback interface on a second network device. That interface is associated with a PIM service between the devices. The first device then forwards the unicast packet across the Layer-3 transport network to the second device.
Career Highlights
The patent highlights Fitzharris’s contribution to network communications, particularly the transport of multicast signaling across Layer-3 infrastructure. Its described approach uses a virtual loopback interface and address translation to support PIM service between network devices.
Collaborations
Fitzharris’s listed coworkers include Abilash Menon and Robert W. Kebler.
Conclusion
Jacob Harrison Fitzharris’s patent focuses on enabling PIM messages to traverse a Layer-3 transport network, contributing a specific approach to multicast service connectivity.
