WG members,


We have posted new version of the draft-white-lsr-distoptflood.
This draft has been around for sometime by name openfabric and
draft-white-distoptflood. The current revision has the name changed
to reflect LSR WG.
This draft describes a flood reduction mechanism in ISIS which is based on
similar mechanisms implemented in OSPF for mobile-ad-hoc Networks
([RFC5449], [RFC5614], and [RFC7182]).

Request working group to review and provide inputs.

Abstract:
   In dense topologies, such as data center fabrics based on the Clos
   and butterfly fabric topologies, flooding mechanisms designed for
   sparse topologies, when used in these dense topologies, can
   "overflood," or carry too many copies of topology and reachability to
   fabric devices.  This results in slower convergence times and higher
   resource utilization.  The modifications to the flooding mechanism in
   the Intermediate System to Intermediate System (IS-IS) link state
   protocol described in this document reduce resource utilization to a
   minimum, while increaseing convergence performance in dense
   topologies.

   Note that a Clos fabric is used as the primary example of a desne
   flooding topology throughout this document.  However, the flooding
   optimizations described in this document apply to any dense topology.




Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
