John Heidemann 2014. Towards Understanding Internet Reliability. Presentation at DHS Cyber Security Division R&D Showcase and Technical Workshop. [PDF]


Since 2006, we have been studying the public face of the Internet. We take regular censuses of the Internet address space, pinging all IPv4 addresses. Recently have studied network outages and events like Hurricane Sandy, probing much of the Internet every 11 minutes. This talk will examine how a single computer can observe outages over the whole Internet continuously. We will discuss how these ideas transition from research to practice. Our work has includes technology transfer and sharing with academia and industry, through hundreds of datasets to more than 50 researchers so far, and joint evaluation of the techniques with other parts of government.
