Patent granted in India to TELEFONAKTIEBOLAGET L M ERICSSON (PUBL)
Patent number 376579 has been granted to TELEFONAKTIEBOLAGET L M ERICSSON (PUBL) which is titled METHOD AND APPARATUS FOR LIMITING DISSEMINATION OF TOPOLOGY AND REACHABILITY INFORMATION IN AN OSPF AREA. The patent applicant responded to this objection by stating that if the present invention provides a technical solution to a technical problem and has a technical effect then the same cannot be considered to fall under the category of algorithm or computer program per se. In light of such observation, the claimed invention is directed towards technical problem, which is regarded as the way to hub and spoke topologies, the remote sites or spokes get much more topology information then they need, this leads to flooding of topology and reachability information that further results in a significant amount of churn. This patent falls under the category of Communication. Overall, this patent covers a network element that acts as a hub in a hub and spoke topology is configured to limit the amount of topology and reachability information that is advertised to a set of one or more remote network elements that act as one or more spokes in the hub and spoke topology in a same routing area.
