Available Datasets
skitter
Beginning Aug 1997 with 4-5 monitors, 60K destinations
Since Mar 2001: 17 monitors, 400K destinations
traceroute + RTT
Analysis tools = iffinder, arts file format analyzers
NLANR MOAT AMP
traceroute (10min interval) + ping (1 min interval)
full mesh among 100 Internet2 sites (VBNS/Abilene campuses)
M Faloutsos: there are end-to-end delays, so couldn't measure one-way delay
Surveyor
traceroute + one-way delay (ippm)
full mesh of 51 monitors
RIPE
traceroute + one-way delay (ippm)
limited to RIPE customers
Mercator
informed, random address probing
one source
july 99 = 3 weeks discussed in Infocomm 00 paper
Infocomm 01 paper?
one-shots, not operational
Cheswick
traceroutes to IP prefixes
one source
two years of continuous data
30% of BGP prefixes
destination coverage better for ATT/Lucent address space
1 snapshot / 6 months
NIST XIWT/IPERF
2 years
17 commercial sites
traceroute (30 min. interval) to 1.7M paths
pingER (30 min. interval) 8.5M pings
postgres database
NIST site has pings (10 pings, 100 & 1k bytes)
