Abstract
Internet availability-the ability for any two nodes in the Internet to communicate-is essential to being able to use
the Internet for delivery critical applications such as real-time health monitoring and response. Despite massive
investment by ISPs worldwide, Internet availability remains poor, with literally hundreds of outages occurring daily,
even in North America and Europe. Some have suggested that addressing this problem requires a complete redesign
of the Internet, but in this talk I will argue that considerable progress can be made with a small set of backwardly compatible
changes to the existing Internet protocols. We take a two-pronged approach. Many outages occur on a fine-grained time
scale due to the convergence properties of BGP, the Internet's interdomain routing system. We describe a novel set of
additions to BGP that retains its structural properties, but applies lessons from fault tolerant distributed systems research
to radically improve its availability. Other outages are longer-lasting and occur due to complex interactions between router
failures and router misconfiguration. I will describe some ongoing work to build an automated system to quickly localize
and repair these types of problems.
