The IESG has received a request from the Link State Routing WG (lsr) to consider the following document: - 'An Algorithm for Computing Dynamic Flooding Topologies' <draft-ietf-lsr-dynamic-flooding-algorithm-04.txt> as Experimental RFC
The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the [email protected] mailing lists by 2026-08-03. Exceptionally, comments may be sent to [email protected] instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract Link-state routing protocols suffer from excessive flooding in dense network topologies. Dynamic flooding alleviates the problem by decoupling the flooding topology from the base topology. Link-state protocol updates are flooded only on the sparse flooding topology while data traffic is still forwarded on the base topology. This document describes an algorithm to obtain a sparse subgraph from a dense graph. The resulting subgraph has certain desirable properties and can be used by a centralized Area Leader to compute a flooding topology for dynamic flooding. This document discloses the algorithm that we have developed in order to make it easier for other developers to implement similar algorithms. We do not claim that our algorithm is optimal, rather it is a pragmatic effort and we expect that further research and refinement can improve the results. We are not currently proposing that this algorithm be standardized, nor that the working group use this as a basis for further standardization work, however we have no objections if the working group chooses to do so. This document is published as an Experimental RFC to gain operational and implementation experience with the specified dynamic flooding algorithm. The intent is to assess the suitability of this algorithm for advancement to the Standards Track as a Proposed Standard, pending sufficient deployment experience and feedback from the community.
