[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The IESG has received a request from the Global Routing Operations WG
(grow) to consider the following document:
- 'Simple Virtual Aggregation (S-VA)'
  <draft-ietf-grow-simple-va-08.txt> as Informational 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
ietf@ietf.org mailing lists by 2012-06-12. Exceptionally, comments may be
sent to iesg@ietf.org instead. In either case, please retain the
beginning of the Subject line to allow automated sorting.

Abstract


   The continued growth in the Default Free Routing Table (DFRT)
   stresses the global routing system in a number of ways.  One of the
   most costly stresses is FIB size: ISPs often must upgrade router
   hardware simply because the FIB has run out of space, and router
   vendors must design routers that have adequate FIB.

   FIB suppression is an approach to relieving stress on the FIB by NOT
   loading selected RIB entries into the FIB.  Simple Virtual
   Aggregation (S-VA) is a simple form of Virtual Aggregation (VA) that
   allows any and all edge routers to shrink their RIB and FIB
   requirements substantially and therefore increase their useful
   lifetime.

   S-VA does not increase FIB requirements for core routers.  S-VA is
   extremely easy to configure considerably more so than the various
   tricks done today to extend the life of edge routers.  S-VA can be
   deployed autonomously by an ISP (cooperation between ISPs is not
   required), and can co-exist with legacy routers in the ISP.
