Web of interconnected networks• Grows with no central authority
• Autonomous Systems optimize local communication efficiency
• The building blocks are engineered and studied in depth
• Global entity has not been characterized

Need for Internet measurements arises due to commercial, social, and technical issues
• Realistic simulation environment for developed products,
• Improve network management
• Robustness with respect to failures/attacks
• Comprehend spreading of worms/viruses
• Know social trends in Internet use
• Scientific discovery
• Scale-free (power-law), Small-world, Rich-club, Dissasortativity,…

Traffic Measurements Monitoring and measuring network traffic
• to produce better models of network behavior
• to diagnose failures and detect anomalies
• to defend against unwanted traffic

Code-Red Worm On July 19, 2001, more than 359,000 computers connected to the
Internet were infected with the Code-Red (CRv2) worm in less than 14 hours

Sapphire Worm was the fastest computer worm in history
• doubled in size every 8.5 seconds
• infected more than 90 percent of vulnerable hosts within 10 minutes.

Witty Worm reached its peak activity after approximately 45 minutes
• at which point the majority of vulnerable hosts had been infected

Nyxem Email Virus Estimate of total number of infected computers is
between 470K and 945K At least 45K of the infected computers were also
compromised by other forms of spyware or botware

Internet Measurements The Internet is man-made, so why do we need to
measure it?
• Because we still don’t really understand it• Sometimes things go wrong
• Malicious users
• Measurement for network operations• Detecting and diagnosing problems
• What-if analysis of future changes
• Measurement for scientific discovery• Creating accurate models that represent reality
• Identifying new features and phenomena
