Hi Everyone,

    A new encoding (called block encoding) for flooding topology is added in this version,
which uses a single structure to encode a block (or part) of topology (maybe whole topology).
It seems much more efficient than others. For example, for 63 nodes flooding topology
of a binary tree, block encoding for this whole flooding topology uses about 100 bytes.
Encoding it through paths uses about 438 bytes. 438/100 = 4.38.

Best Regards,
Huaimo

A new version of I-D, draft-cc-ospf-flooding-reduction-04.txt
has been successfully submitted by Huaimo Chen and posted to the IETF repository.

Name:           draft-cc-ospf-flooding-reduction
Revision:       04
Title:          LS Flooding Reduction

Abstract:
   This document proposes an approach to flood link states on a topology
   that is a subgraph of the complete topology per underline physical
   network, so that the amount of flooding traffic in the network is
   greatly reduced, and it would reduce convergence time with a more
   stable and optimized routing environment.  The approach can be
   applied to any network topology in a single area.





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.
