                  Route Flap Damping Implement Survey
             draft-shishio-grow-isp-rfd-implement-survey-00

Abstract

   Route Flap Damping RFC2439 is a mecanism for BGProute improve the
   stability and reduce the load of CPU of the core routers.

   But it has side-effect,so RIPE has not recommended use of Route Flap
   Damping on RIPE-378 since May 2006.

   On the other hand,there are some reserch reports to improve RFC2439
   such as draft-ymbk-rfd-usable.

   This documentation describes the survey of current service provider
   Route Flap Damping implementation.
