Title: **David A. Carroll: Innovator in Token Ring Networking**
Introduction
David A. Carroll, based in Apex, NC, is a prominent inventor known for his contributions to network technology. With a total of five patents to his name, he has demonstrated a significant impact on the efficiency and functionality of token ring networks.
Latest Patents
Among his most recent innovations is the "Switched Token Ring over ISL (TR-ISL) Network." This patent introduces a technique that efficiently transports token ring (TR) frames over trunks that interconnect switches within a distributed TR bridge. The unique feature of this distributed TR bridge lies in its logical switch fabric, which is shared among interconnected switches through interswitch link (ISL) trunks. Each switch comprises a Bridge Relay Function (BRF) linked to multiple Concentrator Relay Functions (CRFs) that receive TR frames over TR segments. The patented method encapsulates TR frames within a TR-ISL protocol format, ensuring compatibility with varying TR frame formats and adhering to the 2-tier switching model of the distributed TR bridge.
Another notable patent is the "Distributed Ring Protocol and Database." This invention encompasses a Distributed Ring Protocol (DRiP) that maintains and disseminates information within a distributed token ring (TR) bridge featuring a logical switch fabric over a TR switching network interlinked by trunk connections, such as ISL trunks. The DRiP manages critical information enabling switches within this ISL switched fabric to assess the status and configuration of ports in the distributed bridge.
