Among the passive data sources available to CAIDA are monitoring locations in several large Internet Service Providers (ISPs) in the United States. These taps collect packet headers at large peering points and the resulting traces have been used for a wide variety of research projects, ranging from general attempts to characterize the global state of Internet traffic, specific studies of the prevalence of peer-to-peer filesharing traffic, to testing prototype software designed to stop the spread of Internet worms.
Passive Data Monitors
