4. Henk Uijterwaal. NANOG-26, October 29, 2002. http://www.ripe.net/test-traffichttp://www.ripe.net/test-traffic 4 TTM 101 Project to do performance measurements on the Internet –Delay –Loss –Routing One way, active, “real” traffic Inter-provider networks only –Hard for individual provider –Techniques can be used for internal networks though Scientifically defendable, well defined standards –IETF IPPM, RFC’s: 2330, 2679, 2680,...

5. Henk Uijterwaal. NANOG-26, October 29, 2002. http://www.ripe.net/test-traffichttp://www.ripe.net/test-traffic 5 TTM Service Goals Black box –No configuration by the user –No user access –Guarantees well-defined environment for the measurements Easy to install, little maintenance Available to the entire community All you have to do, is to look at the results

CDMA –3 rd generation mobile phone standard –Phones needs a time signal –GPS Sync’ed base stations broadcast time signal Can this be used for TTM?

8. Henk Uijterwaal. NANOG-26, October 29, 2002. http://www.ripe.net/test-traffichttp://www.ripe.net/test-traffic 8 CDMA Clocks Yes! Same accuracy Praecis CT –“Phone without speaker, mike and keypad” –http://www.endruntechnol ogies.comhttp://www.endruntechnol ogies.com Works everywhere your cell phone works Simply mount on a wall –$0.02 installation costs

19. Henk Uijterwaal. NANOG-26, October 29, 2002. http://www.ripe.net/test-traffichttp://www.ripe.net/test-traffic 19 RIS 101 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 AS3AS4 www.x.com Router AS5 User Router AS1

20. Henk Uijterwaal. NANOG-26, October 29, 2002. http://www.ripe.net/test-traffichttp://www.ripe.net/test-traffic 20 Motivation Something is wrong with your routing Current tools: –Log in to your router –Use a looking glass on other routers 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)

21. Henk Uijterwaal. NANOG-26, October 29, 2002. http://www.ripe.net/test-traffichttp://www.ripe.net/test-traffic 21 Goals of the RIS Set up route collectors that collect BGP announcements between AS’s Time-stamp and store in a data-base Set up interactive queries to database –Giant looking glass with history –Network reachability from other networks Provide raw data and statistics –for reality checks, RRCC project –to generate trend analysis Available to the Community
