The Internet has emerged over the past decade as a critical piece of telecommunications infrastructure, yet the measured availability of the Internet is at least two orders of magnitude less than the telephone network. As there is no single silver bullet, we have been looking at how to attack the problem both architecturally and through immediately deployable diagnostic services. For outages that occur over short time scales, we address availability problems at the network protocol layer, by developing provably more reliable algorithms for routing using techniques from the theoretical distributed systems community. For long-term outages, we address the problems at the management layer, by using timely alerts and automated diagnosis to identify connectivity problems so that ISPs can address them. |
