Title
(EN) DISTRIBUTING INFORMATION IN COMMUNICATION NETWORKS
Abstract
(EN)

Methods and apparatus for distributing link state information are provided. Network nodes propagate link state information via a control plane flooding operation. A first network node can initiate this propagation in response to a local link state change. In addition, some network nodes can via data plane messaging to transmit link state information to a remote node of the network. The remote node responds to the message by initiating a control plane flooding operation at that location. The remote node can be selected based on a variety of criteria, such as network traffic conditions, location, or network topology. Multiple remote nodes can be prompted in this manner to initiate flooding operations.
