Long-term pointing stability at synchrotron light sources using conventional rf-based particle beam position monitoring is limited by the mechanical stability of the pickup electrode assembly. Photoemission-based photon beam position monitors for insertion device beams suffer from stray radiation backgrounds and other gap- dependent systematic errors. To achieve the goal of 500-nanoradian peak-to-peak...
Guaranteed levels of network resilience are essential for many emerging and future Internet services. Currently, the only network model that can support stringent resilience requirements is a provider-based overlay network. In such an environment, resilience can be implemented either in the overlay networks or in the physical network. In this paper we look at how the network provider revenue is affected...
In this paper we consider dynamic routing of restorable quality of service (QoS) connections in multi-protocol label switched (MPLS) networks under a single link failure model. To route a restorable QoS connection, two link disjoint label switched paths from the ingress to the egress node need to be computed such that both paths comply with the QoS constraints. When looking at QoS constraints like...
