Pie(s) in the Sky Mark Crovella Boston University Computer Science
Basic Science How many computers are connected to the Internet? –IP addresses? –Routers? How many objects are accessible via –HTTP? –P2P? How are these quantities changing over time and location? Where are these computers and files?
Network Performance Realtime hotspot characterization –where, when, and for how long do loss and congestion events occur in the wide area? Network simulation –How can we use simulation to aid design decisions about wide area services? Topology generation Source – modeled traffic generation
Security How resistant is the Internet and its services to attack? –What are the weaknesses? –How strong are the adversaries? (Google on: "Now retired from spam fighting) How can we enforce protection of Internet resources? –Legal remedies exist, but need tools for –Tracing and identifying attackers
