Why a RIS ?
• Global routing behavior affects I(S)P service
• Distant routing problems are difficult to
diagnose
• ‘Routing quality’ of neighbors is difficult to
assess
• Destination based routing provides ‘one-wayonly’ control & diagnostics
• Looking glasses are a crude tool to cover the
‘other direction’

What is RIS?
• “Looking Glass on Drugs”
• Multiple route collectors integrate multiple
views
• Database provides access to more than just
instantaneous data
• Database supports various (longer term)
analysis products
• Multiple collectors and database enable
complex analysis products

–
RIPE NCC, + 15 peers worldwide
LINX, + 40 peering sessions from LINX members
AMS-IX, installed 16/1
SFINX, in transit
• Next steps:
–

–
Investigate the added value from more RRC’s?
Where to locate the next RRC’s?

Asinuse Tool
• Presents ‘Peering History’ of an AS
– current main user is RIPE NCC registration staff
– after informal announcement other users appeared
live
• Example: AS4777
– takes 1-3 minutes, whole database searched
– provides links to regstration data
– useful to check out your own AS
