Content distribution networks (CDNs) built on clouds have recently started to emerge. Compared to conventional CDNs, cloud-based CDNs have the benefit of cost efficient hosting services without owning infrastructure. However, resource provisioning and replica placement in cloud CDNs involve a number of challenging issues, mainly due to the dynamic nature of demand patterns. To deal with this dynamic...
The FlexRay communication protocol is expected to be the de-facto technique standard for the next generation high-speed networks on vehicles. A number of recent studies has thus investigated message scheduling techniques for FlexRay systems. However, most existing work focused on either the scheduling of periodic messages on the static segment or the scheduling of hard aperiodic messages on the dynamic...
Network virtualization decouples the traditional Internet Service Provider (ISP) into the infrastructure provider (InP) and the service provider (SP). Disruptive technologies hence can be easily employed by the SP and transparently mapped to the physical network managed by the InP after resolving the network embedding problem. In this work, we investigate the survivable network embedding (SNE) problem...
Network virtualization is regarded as a promising solution to the revolution of the current Internet. With virtualization, disruptive technologies can be easily deployed over the logic (service) network and transparently mapped to the physical network via the network embedding process. In this work, we address the survivability issue in the virtualization context via resolving the survivable network...
