• http//www.ripe.net/ris/
• RIPE36, Budapest, May 2000

2
Overview

• Introduction
• Progress since RIPE35
• Current setup
• Some interesting observations in the data
• Plans for the next months

3
Goals of the RIS

• Collect default-free time-stamped BGP
  announcements between ASs and store in a data
  base
• At several points on the internet
• Set up interactive query to database
• Giant looking glass with history
• Network reachability from other networks
• Provide raw data
• for reality checks, IRR/RC
• to generate trend analysis
• Available to the Community

6
Progress since RIPE35

• Set up peering sessions with interested parties
• Store data
• Work on user-interface
• Data-analysis
• Work on the open questions in the design document
• Finalized hardware for the RRCs.

7
Research topics

• What is the best data-base to store the
  information? (time series data)
• How long should the data be online? What should
  be done with the old data?
• Determine the optimal number of routing table
  dumps per day
• Scalability of Collector Software MRT Zebra
• How to turn this into a regular service?
• ...

Current setup

• A Remote Route Collector
• Pentium III with 2 NIC, lots of memory and disk
• Collection software MRT
• A machine to store and analyze the data
• Set up about 13 EBGP sessions
• Collecting raw data since October
• Database contains data since May 2000

Remote Route Collector (RRC)

• BGP4 ipv4 announcements between AS
• AS path origin AS
• Route prefix and length
• BGP attributes
• Errors in the BGP announcements
• Snapshots of routing table 3/day
• RRCs do not announce routes to peers
• RRCs will not forward IP traffic to peers

Possible Queries to RIS Database

• Dump from RIB and Updates
• Computed state at the exact query time
• Examples
• 193.0.0.0/22 updates since yesterday
• Prefixes originating from AS3333
• Who announced 193.0.0.0/22 yesterday
• Your suggestions...

23
Plans for the next months

• Add more features to our current setup
• User feedback
• Reduce delay in Updating Database
• Look in more detail at the data-base
• Which product should we use?
• Order and install
• Set up more RRCs around the world
• Operational issues
• Scalability of Collector Software

24
Plans for the next months (2)

• Continue working on the open questions
• More peering sessions?
• Yes, always as long as we can store the data
• Contact Antony to set this up
• Analysis of the data
• Periodic reports about routing table
• Collaboration with other efforts in this area
• How to turn this into a regular service?

25
Conclusions

• Development of the RIS according to schedule
• Prototype RIS available for general use
• Demonstration in the terminal room
• Your feedback is welcome
• Lots of interesting effects in the data
• More at RIPE-37!
