Synergistic Network Operations

Saqib Raza

About the talk:
Modern communication networks have multiple ongoing operations that jointly realize the services offered by the network. In the interests of modularity and design simplicity, individual operations correspond to very specific tasks and are optimized for them. Nevertheless, complex interactions may exist between operations, and design and procedural choices made for one operation can potentially impact the performance of another. Improving synergy amidst network operations implies that individual operations cooperate advantageously to enhance the overall efficiency of the network. This talk looks at two case studies of synergistic network operations. Firstly, we investigate how premeditated management operations e.g. routine maintenance can impact core network operations. We present the Graceful Network State Migration framework that provides for judicious scheduling of such premeditated management tasks towards the end of minimizing network disruption. Secondly, we discuss MeasuRouting which is a framework for routing-assisted traffic measurements. MeasuRouting synergizes intra-domain traffic engineering operations with measurement operations by routing critical traffic sub-populations across paths where the appropriate monitoring infrastructure is deployed. MeasuRouting achieves this greater monitoring performance while working within the constraints of intra-domain traffic engineering policies.

About the speaker:
Saqib Raza is a final year Ph.D. candidate in the Computer Science department at the University of California, Davis where he is advised by Prof. Chen-Nee Chuah. He received his M.S. in Computer Science from the University of California, Davis in 2007 and his B.S. in Computer Science from Lahore University of Management Sciences, Pakistan in 2004. Saqib’s research interests span network algorithms, traffic engineering, network measurement, optimization, and graph theory. The focus of Saqib’s research is to jointly optimize design and operational decisions of disjoint network operations for maximum global network efficiency.
