We present a technique for computing upper bounds on the distribution of individual per-session performance measures such as delay and buffer occupancy for networks in which sessions may be routed over several "h...

Diffusion models and mean-field models have been used to approximate many stochastic dynamical systems. A functional strong law of large numbers or a functional central limit theorem justifies such an approximation. Such a result, however, does not justify the convergence of the equilibria of pre-limit systems to the equilibrium of a limit system. In this talk, I will touch on three recently developed methods for justifying equilibrium convergence in the setting of bandwidth sharing networks and multiclass queueing networks, with a focus on moment generating function method and the state-space-collapse. Based on joint works with Anton Braverman, Chang Cao, Masakiyo Miyazawa, and Xiangyu Zhang..

The utility of using operational models of services to determine the measurements and correlation techniques necessary to detect and diagnose problems with the services is examined using experiences from an in-system programmable (ISP) system. These experiences demonstrate the value of designing a monitoring system based on models of services, while the diagnosis scenario demonstrates the immense value of correlating measurement results based on service models for problem diagnosis.
In a public cloud, bandwidth is traditionally priced in a pay-as-you-go model. Reflecting the recent trend of augmenting cloud computing with bandwidth guarantees, we consider a novel model of cloud bandwidth allocati...

We consider the problem of finding the graph on which an epidemic spreads, given only the times when each node gets infected. While this is a problem of central importance in several contexts - offline and online soci...
