Hey guys, A longer heads-up would have been nice, something like a week. This 24 hour notice is unfortunate. Thanks, Christian On 6/15/05 5:27 AM, "Lorenzo Colitti" <lorenzo@ripe.net> wrote:
Hi,
as part of our AS-set stuffing experiments (announced, including links to in-depth information, in [1]), we will be announcing unusually large AS-sets tomorrow, Thursday 16 June.
The prefixes involved will be 84.205.73.0/24 and 84.205.89.0/24, both orignating in AS12654. The AS-sets will consist of AS12654 repeated n times, thus the paths will look like 12654 {12654, 12654, ..., 12654}. No other AS numbers will be used. The values of n we will use are 25, 50, 75 and 100.
The announcements are designed to discover how far large AS-sets are propagated, and thus how effective our techniques can be, in today's Internet with today's IPv4 operational practices. This is *not* a test to see if routers will fall over: we have successfully tested longer AS-sets in the lab on both Cisco and Juniper, and longer AS-paths and AS-sets have been observed in the wild [2,3]. See [1] for more information on the safety of these announcements.
The proposed schedule is as follows:
84.205.73.0/24 84.205.89.0/24 14:00 UTC: 25-element AS-set 50-element AS-set 14:30 UTC: withdrawal withdrawal
16:00 UTC: 75-element AS-set 100-element AS-set 16:30 UTC: withdrawal withdrawal
If anyone should see a problem during the announcements, please contact me and I will take immediate action.
Regards, Lorenzo
