PART 1IP Performance Measurement Case Study(What we did)

The settingLarge-scale test of seven of the worlds biggest ISPs28 measurement nodes (cNodes) on backbone core of:Cable & Wireless (C&W)Level 3 CommunicationsQwest CommunicationsSavvis CommunicationsSprint Corp.VerioWilliams Communications

Measurement packet generationTest ran 30 days; total project took more than a year to completecNodes generated 4,558,388,076 packets during the month of August 2002All told, we collected 156,050,656 discrete measurementscNodes record more than 70 IP metrics but in this test we focused on just three: uptime, jitter, and packet loss

Packet typesThe cNodes generated vectors of both 1,518 byte TCP and 256 byte UDP packetsWith each cNode sending packets to three other cities there were a total of six vectors per cNodecNodes configured to generate an aggregate transmit rate for all vectors not to exceed 512 kbit/s.
