Latest Patents
One of her latest patents is titled "Policy-based forwarding in open shortest path first (OSPF) networks." This invention introduces a method and system that enables policy-based traffic forwarding in a data network. It implements policy-based control over the propagation of Link State Advertisement (LSA) messages through the network. A route tag is asserted in respect of an LSA message advertising a network address. The propagation of the LSA is controlled using the asserted internal route tag, allowing for policy decisions such as Pass and Discard. Additionally, the forwarding table may be updated using the route and address information contained in the LSA, with routes tagged as inclusion or exclusion routes based on an exclusion route flag.
Another significant patent is "Dormant backup link for OSPF network protection." This invention provides protection against resource failures in OSPF networks without increasing the complexity of the network topology. An internal router automatically maintains a backup link in a dormant state until a network failure affecting communications with a primary adjacent area border router (ABR) is detected. Upon detection of the failure, the internal router activates the backup link to enable traffic flow to an alternate adjacent ABR, bypassing the failure. Once communications with the primary ABR are restored, the backup link is deactivated, ensuring simplicity in network management.
