CIDR report.

17 Sep 1996

      Okay,
	after taking in a few comments. Here's what I will distribute
automatically starting this Friday at 12:00 PDT. Note I have changed
things around a little and added a general section with a couple of
hopefully useful data points.

Comments directly to me are still welcome.

	Cheers,

		--Tony

P.S. It seems section 3 has been very useful in helping folks 
     find leaks they didn't know they had.

It is not checked before it leaves my workstation.  However, hopefully 
you will find this report interesting and will take the time to look 
through this to see if you can improve the amount of aggregation you 
perform.

The report is split into sections:

   0) General Status

      List the route table history for the last week and give some status
      on ASes.

   1) Gains by aggregating at the origin AS level

      This lists the "Top 30" players who if they decided to aggregate
      their announced classful prefixes at the origin AS level could 
      make a significant difference in the reduction of the current 
      size of the Internet routing table. This calculation does not 
      take into account the inclusion of holes when forming an aggregate
      so it is possible even larger reduction should be possible.

   2) Weekly Delta

      A summary of the last weeks changes in terms of withdrawn and
      added routes. Please note that this is only a snapshot but does 
      give some indication of ASes participating in CIDR. Clearly,
      it is generally a good thing to see a large amont of withdrawls.

   3) Interesting aggregates

      Interesting here means not an aggregate made as a set of 
      classful routes.      

Thanks to xara.net for giving me access to their routing tables once a
day. 

Please send any comments about this report directly to me.
In the future I hope to put some (or most) of this report up on the
web.

2) Weekly Delta

This a daily snapshot of changes in classfull routes being withdrawn and added.
the deltas are calculated over a rolling 7 day period. Please bear in mind this
is purely a "snapshot" and a large flucuation could be caused by a connectivity
problem for example. However, this does give some indication of service
providers that are moving to classless routing.
