Title: Towards a Reliable Optimized Intradomain Routing
Abstract: Routing within an organizational network, or intradomain routing, is a crucial, yet highly challenging task. Today’s routing protocols (e.g., OSPF and ECMP) can suffer from long re-convergence times as a result of link/node failures and provide network administrators with indirect, coarse-grained control over how traffic flows in their networks. Worse yet, the vast majority of networks lack the measurement infrastructure needed to asses the impact on performance of changes to network configuration. Consequently, most network operators tend to stick with the default configuration parameters, changing them very carefully and only in response to undesirable outcomes.
I will present results highlighting the limitations of today’s routing and flow optimization mechanisms. I will then describe results in two new directions for optimized, more reliable intradomain routing: (1) handling network failures in the data plane, that is, without waiting for re-convergence of routing protocols, and (2) turning ideas from theoretical research on oblivious routing into an operational reality.
Bio: Marco Chiesa is a postdoctoral researcher at the Hebrew University of Jerusalem. He received his Master and Ph.D. degree in computer science and automation at the Roma Tre University (Italy) in 2010 and 2014, respectively. His research activity is primarily focused on routing protocols, including theoretical analysis of convergence, security, and traffic-engineering problems.
