During the past several decades, a great number of R&D achievements have been attained. During the period from 1986 to 1999, for example, 135 pharmacutical projects won prizes of the CAS awards for natural sciences, inventions and S&T progress (roughly ac-展开更多

Through virtualization, multiple customized virtual networks(VNs), requested by users, are allowed to coexist on the underlying substrate networks(SNs). In addition, the virtualization scheme contributes to sharing underlying physical resources simultaneously and seamlessly. However, multiple technical issues still stand in the way of NV successful implementation. One key technical issue is virtual network embedding(VNE), known as the resource allocation problem for NV. This paper conducts a survey of embedding algorithms for VNE problem. At first, the NV business model for VNE problem is presented. Then, the latest VNE problem description is presented. Main performance metrics for evaluating embedding algorithms are also involved. Afterwards, existing VNE algorithms are detailed, according to the novel proposed category approach. Next, key future research aspects of embedding algorithms are listed out. Finally, the paper is briefly concluded.展开更多

It is so far the only State Key Laboratory (SKL) specifically in the field of Traditional Chinese Medicine (TCM) over the country. It is also the jothed-laboratory partner of the State Key Laboratory of Natural and Biomimetic Drugs at the Peking University.展开更多
