Network virtualization is a key technology in future internet which allows multiple virtual networks to coexist in isolation with each other. This paper proposes an efficient resource allocation algorithm called HITS-PQ for multiple types of virtual networks. HITS, which has been an algorithm for page ranking, is used in node mapping since it considers the topology and resources of the whole network instead of only the neighbor nodes. Links are mapped using path-split and queue strategy, which supports different kinds of VNs. Experimental results show that HITS-PQ has a better performance in increasing long-term revenue, acceptance ratio and R/C ratio compared to the baseline algorithms.

Keywords:Computer network; Network virtualization; HITS; Resource allocation
