Patent AT-E401719-T1: [Translated] TRAFFIC NETWORK FLOW CONTROL USING DYNAMIC MODIFIED MERITS FOR REDUNDANCY CONNECTIONS

Published by National Center for Biotechnology Information (NCBI) | U.S. Department of Health & Human Services | Catalog Last Checked: September 07, 2025 at 11:27 AM | Dataset Last Updated: September 06, 2025
Distance vector routing protocols such as the Routing Information Protocol fail to rapidly reconfigure to use redundant links. By modifying the outgoing advertised hop count upon detecting a failure in a connection for which a backup or redundant connection exists, incoming traffic is diverted to the redundant or backup connection. An artificially high hop count is advertised for a given port, and when a failure or loss of reachability occurs in a connection associated with that port, an advertisement of a lower hop count on the backup or redundant connection for the given port is triggered. This causes rapid rerouting of incoming traffic to the backup or redundant connection.
