METHOD AND APPARATUS FOR DESIGNATED ROUTER SEAMLESS SWITCHOVER - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240348537 titled 'METHOD AND APPARATUS FOR DESIGNATED ROUTER SEAMLESS SWITCHOVER
The abstract describes a method and apparatus for designated router (DR) seamless switchover in a network device, specifically in an Open Shortest Path First (OSPF) network.
- Detecting a DR failure event due to a failed DR.
- Detecting that the second edge device is unreachable.
- Holding refresh of Router-Link State Advertisements (Router-LSA) in a link-state database and flooding procedure.
- Ensuring a Backup Designated Router (BDR) has not declared to be a working DR in the OSPF network.
Potential Applications: - Networking infrastructure - Telecommunications - Data centers
Problems Solved: - Seamless switchover in case of DR failure - Maintaining network stability and connectivity
Benefits: - Improved network reliability - Reduced downtime - Enhanced network performance
Commercial Applications: Title: "Enhanced Network Reliability Solution for OSPF Networks" This technology can be used by network equipment manufacturers, service providers, and enterprises to ensure uninterrupted network operations and minimize disruptions.
Questions about the technology: 1. How does the method detect a DR failure event and ensure seamless switchover? - The method detects a DR failure event by monitoring the network for any issues with the designated router. It then seamlessly switches over to a backup designated router to maintain network stability. 2. What are the key benefits of using this technology in OSPF networks? - The key benefits include improved network reliability, reduced downtime, and enhanced network performance.
Original Abstract Submitted
embodiments of the present disclosure provide method and apparatus for designated router (dr) seamless switchover. a method performed by a network device comprises detecting a dr failure event due to a failure dr. the method further comprises detecting that the second edge device is unreachable. the method further comprises holding refresh of router-link state advertisements (router-lsa) in a link-state database and flooding procedure, when a backup designated router (bdr) has not declared to be a working dr in an open shortest path first (ospf) network.
