  • Fast designated router transitions in broadcast networks for link state protocols
    Patent number: 9832108
    Abstract: A method, apparatus and computer program product for providing quick designated router transitions in broadcast networks is presented. An Alternate Designated Router (ADR) in a network detects node failure of a Designated Router (DR) prior to other nodes of the network detecting the failure of the DR. In response to the detecting node failure of the DR, the ADR floods the network with a link state packet of a pseudonode within the network. At least one other node of the network detects failure of the DR. The at least one other node computes routes to take into account the failure of the DR by the at least one other node of the network, wherein there is minimal traffic loss since the pseudonodes link state packet is already present before the computing routes takes place.
