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 the authors have developed
   in order to make it easier for other developers to implement similar
   algorithms.  The authors do not claim that our algorithm is optimal,
   rather, it is a pragmatic effort and the authors expect that further
   research and refinement can improve the results.

   The authors are not currently proposing that this algorithm be
   standardized, nor that the working group use this as a basis for
   further standardization work; however, the authors 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.
