Hi all,
First, thanks for using Cyclops, and thanks for all the Cyclops users
that drop me a message about this.
It seems some router in AS13214 decided to originate all the prefixes
and send them to AS48285 in the Caymans, all the ASPATHs are 48285
13214.
The first announcement was on 20

Jack,
Please give me your ASN and i'll double check our data. As long as the
network has 4 or less downstreams, it's being labeled as "stub".

Hi,
The classification we have is one possible classification, it's hard
(if not impossible) to capture the diversity of the network in 4
classes without having mislabels. We noticed that there were a
considerable number of networks with special arrangements (i.e. a very
small number of lo
It seems Team Cymru needs to update its whois db to use 4-byte ASNs
and remove AS_TRANS (23456)

Hi,
Just to let you know about Cyclops (beta for now), a tool for topology
visibility and real-time routing anomaly detection/alerting for
service providers and enterprise networks. Cyclops uses real time data
from hundreds of vantage points of route-views, ripe-ris, packet

Moazzam,
Do you have something specific in mind you want to measure? e.g.
convergence times, table size, update count, etc? the scope of your
study seems to broad as you describe it..

Topological aggregation based on ASN is often too course granularity,
see this paper:

specifically Fig4 is a good example, and sec 4C.

Hi all,
We're having an issue with an UPS here at UCLA where one of the
