ABSTRACT
With the increasing number and variety of network business, the existing Internet architecture can’t be able to meet the ubiquitous, heterogeneous and credible requirements of advanced services at home and abroad. Many new institutions and individuals have begun to research the next generation of network’s architecture which is called reconfigurable network. Reconfigurable network can be divided into Atomic Capability layer and Atomic Service layer and Business layer. In order to achieve effective cooperation between the upper and lower layers in the hierarchical model, this study plans to design a "mapping" mechanism to complete the virtual network requests between upper and lower layers. This study proposes a virtual link embedding and virtual node embedding algorithm to complete the service request process. Simulation result shows that: the algorithm plays an important role in improving the utilization of network resources as well as energy saving.
