Event Description

Abstract: Many stochastic networks are too complex to be amenable to exact analysis. Instead, one aims to obtain tractable approximations that provide qualitative insight into the dynamics and whose accuracy can be rigorously justified via limit theorems in a suitable asymptotic regime. However, many complex networks fall outside the purview of existing methods. We introduce a novel representation of randomized load balancing networks in terms of interacting measure-valued processes. We describe their scaling limits and show how they can be used to provide insight into both the transient and equilibrium performance measures of the network.
