Aggregation Summary
The algorithm used in this report proposes aggregation only
when there is a precise match using the AS path, so as
to preserve traffic transit policies. Aggregation is also
proposed across non-advertised address space ('holes').

Hi,
as announced to the RIPE routing working group mailing list [1] and
elsewhere, over the next few days the Computer Networks research group
at Roma Tre University, in collaboration with the RIPE NCC RIS project,
will be performing experiments involving announcements with large
AS-sets in the AS-path. We are doing this to test innovative network
discovery methodologies we developed to allow ISPs to determine how
their prefixes are seen by the rest of the Internet. The announcements
will be for prefixes 84.205.73.0/24 and 84.205.89.0/24 and will
originate in AS12654.
We have been performing similar experiments over IPv6, in collaboration
with the NAMEX internet exchange, since December 2004 with no ill
effects; furthermore, our announcements are standard BGP, so conformant
implementations should be able to process them, and very long AS-sets
have already been observed in the past (e.g. [2], [3]). However, we want
to be careful to avoid router bugs on legacy devices, old firmware
versions and the like, so we are first sending out test announcements
with progressively longer AS-sets. Should you encounter a problem with
these advertisements, please let us know and we will withdraw them.
The proposed timetable of the test announcements is as follows.
2005-03-04:
14:00 UTC: 10-element AS-set
14:30 UTC: withdrawal
16:00 UTC: 25-element AS-set
16:30 UTC: withdrawal
and, if there are no problems:
2005-03-07:
14:00 UTC: 50-element AS-set
14:30 UTC: withdrawal
16:00 UTC: 100-element AS-set
16:30 UTC: withdrawal
Note: For reference, the AS-sets already observed in [2] and [3]
contained 123 and 124 ASes respectively.
For questions/comments, please contact compunet(a)dia.uniroma3.it or
lorenzo(a)ripe.net.
Regards,
Lorenzo Colitti

Dear Colleagues,
The RIPE NCC received the AS Number Block 34816 - 35839 from
the IANA in February 2005.
You may want to update your records accordingly.
Kind regards,

Hi all,
for research purpose I am looking for some facts concerning
inter-domain AS-path failures. Does anyone of you knows some
cites or sources were I can get some numbers on that issue?
I am aware that I might ask for network internals that are
usually kept secret or at least not public ;-). Anyway if
anyone could give me a hint where to find some information
about :
. Percentage of inter-domain AS-path failures (total amount
of inter-domain failures)
. How often do inter-domain AS-path failures occur?
I would really appreciate!
Btw. I do know the Sigcomm Paper "Understanding BGP Mis-
configuration".
cheers,
- goetz

[Apologies for duplicate emails]
Dear colleagues,
In the next few days, the beacon prefixes 84.205.73.0/24 and
84.205.89.0/24 will be used by researchers at the Computer Networks
research group at Roma Tre University, in collaboration with the RIPE
NCC New Projects Group, to perform studies on network topology discovery.
The objective of the experiments is to investigate new methodologies for
topology discovery and experimental mechanisms for deducing the routing
policies of ISP's, the quality of their connectivity, and more general
properties of interdomain topology.
The experiments will involve announcing AS-sets of varying lengths
behind AS 12654 and are initially scheduled for the last week of
February and the first week of March.
For further information, or for questions and comments, please contact
compunet(a)dia.uniroma3.it or lorenzo(a)ripe.net.
On behalf of the Roma Tre Computer Networks research group and the RIPE
NCC New Projects group.
Regards,
Lorenzo Colitti
