Paper Abstract

We propose a programmable automatic protection switching (APS) protocol to repair an impaired lightpath traversing an optical link. Recovery agents repair impaired flows by searching through a space of policies before attempting a protection switch and after switching impaired traffic. A policy manager disseminates a changeable set of policies to each agent and ensures consistent interpretation end-to-end QoS. QoS policies are structured to be interpreted in the same way by developing a model of end-to-end QoS over which logic formulae can be checked for satisfaction.
