One of the most fundamental issues in network virtualization is the virtualization of the substrate nodes. Reconfigurable Router (RR) realizes a flexible router architecture based on the idea of hardware virtualization which is performed by component-based processing and reconfiguration. But if the components are incompatible with each other in terms of performance, the RR will get lower performance...
With network virtualization more and more popular, how to protect the virtual networks (VNs) from a single substrate link failure is increasingly important. Existing protection schemes like dedicated backup and shared backup, suffer from high resource cost and delayed recovery, respectively. To offer instantaneous recovery with less redundant resource, in this paper, we propose a coding-aware VN mapping...
The reactive power characteristics of doubly fed variable speed constant frequency (DFVSCF) wind power generator are important for grid's voltage stability and generator's low voltage ride-though (LVRT) capability. From the equivalent circuit of doubly-fed induction generator (DFIG), the balance equation of reactive power was deduced. Based on the balance equation, this paper first discussed the reactive...
