Abstract

The rise of popular online services such as online social networks and user generated content has dramatically changed the landscape of the Web. With millions of users viewing and uploading large volumes of content, services are now delivered using large-scale data centers comprised of tens of thousands of servers. At this scale, ensuring data is delivered securely and reliably to clients is paramount. This talk will focus on the challenge of Internet routing security and then briefly cover data center reliability, two challenges currently facing popular online services.

The Internet’s routing system is surprisingly vulnerable to attack, however, deployment of security solutions (e.g., S*BGP) has been at an impasse for more than a decade. I will first present our three-step strategy to create economic incentives for deploying S*BGP. The cornerstone of our strategy is S*BGP’s impact on network traffic which we harness to drive revenue-generating traffic toward ISPs deploying S*BGP, thus creating incentives for deployment. In the second part of the talk, I will briefly cover my empirical study of data center network reliability in a network comprised of tens of data centers and thousands of devices.
