Outline

• Introduction• Remote Route Collectors• Making the RIS more useful for daily

operations• Data analysis• Conclusions


What is the RIS?

• AS1’s NOC gets a user complaint:– “Last night, I could not reach www.x.com.”

• AS1’s NOC looks at the current routing tables– “Well, it works now”

AS2

AS3 AS4www.x.com

AS1


Motivation

• Problem with your (AS-level) routing• Current tools:

– Log in to your router– Use a looking glass on other routers

• All kinds of problems:– How to find right looking glass?– What if the looking glass cannot be reached either?– Accessing multiple LG’s takes a lot of time– No history mechanism

• Solution: Routing Information Service (RIS)


The RIS

• Collects default-free time-stamped BGP announcements between AS’s and store them in a data base– At several points on the Internet

• Set up interactive queries to database• Provide raw data• Provide analysis• Available to the Community


Outline




Remote Route Collectors

• Collect BGP updates from all interested parties at an IX

• 4 new collection points since last year• Next:

– MAE-west– US east coast

Your data in the RIS?

• Yes, please!

• Send peering information to:– [email protected]– http://abcoude.ripe.net/ris/peerreg.cgi

• The RIS will not announce any routes, nor will it send any traffic to your site


Administrative stuff

• RIS users lists: [email protected]– Majordomo

• Operational information– Announcements about changes in the RIS– Downtime– Problems with the data

• Future: Discussion of problems when analyzing the data


Outline




Making the RIS more useful for daily operations

• FAQ with answers

• Manual– Typical examples/cases studies– Annotated screen dumps – Will add more cases– Let us know if this is useful


Manual example


Looking Glass on the boxes

• There is a time-gap between data-collection and data-insertion– 1 hour

• To cover this, we added a Looking Glass on the RRC– Standard Looking Glass code– Available on all rrc’s

• Start from RIS homepage


Top10 of most active prefixes

• Generates lists of the most active prefixes– Announcements or withdrawals– Top10, 25 or 50– 3, 6, 12 or 24 hours

• Large number of updates may indicate a problem

• CGI-script to find them– Available on demand– We will run it regular to produce a monthly top10

• http://abcoude.ripe.net/ris/topten.cgi

Most active prefixes

• Next steps:– Top10 by origin AS– Look for Withdrawal-Announcement sequences

• “Flaps”

• Produce statistics


Outline




RISreport

• First version released last summer• Wanted to add new plots• Scalability problems• Decided to re-implement the SQL2RRD tool

– November-January– Switch over in the next weeks

• Long list of variables that can be added

Outline




Conclusions

• FAQ and a manual, to make the RIS more useful for daily operations

• New queries• More data

• Next steps:– Extend RISreport– Flaps– Your feedback
