Title: Keith E Karlsson: Innovator in Network Resiliency
Introduction
Keith E Karlsson is a notable inventor based in Raleigh, NC (US). He has made significant contributions to the field of network resiliency, holding a total of 3 patents. His work primarily focuses on improving connection reliability in network systems.
Latest Patents
One of Karlsson's latest patents is titled "Method and system for LEC resiliency with fast failover." This invention addresses the need for connection resiliency by defining two LECs in normal practice, which typically involves a lengthy recovery procedure in the event of an ATM interface failure. In contrast, Karlsson's innovation configures only one LEC. If the active ATM interface fails, the bridge is not notified, allowing the LEC to associate itself with an alternate ATM and rejoin the ELAN via the alternate ATM interface. This process is part of the LAN Emulation protocols, and once rejoined, the LEC automatically re-establishes previously existing Data Direct VCCs using its LE_ARP cache entries.
Another significant patent by Karlsson is "Control of non-resettable counters by multiple processes." This invention allows multiple processes to share a single set of non-resettable counters, which are sampled periodically. Each process maintains a unique list of counter relationships and compares current sampled counter values with previously received values to establish a counter reset value based on specific conditions.
