A traditional substrate network is usually managed by multicast InPs, and many applications in the substrate network can be characterized by hybrid virtual networks with both unicast and multicast requests. However, to the best of our knowledge, few researches focus on the problem of hybrid virtual network mapping across multiple domains (HVNMMD). In this paper, we investigate the HVNMMD problem and propose two algorithms to solve this problem efficiently: i) the decomposition-based algorithm, HVNMMD-D; and ii) the spectral clustering based algorithm, HVNMMD-SC. We evaluate the performance of our algorithms through conducting simulation experiments. The simulation results show that the proposed algorithms perform better than existing approaches.This research was partially supported by the National Grand Fundamental Research 973 Program of China under Grant (2013CB329103), Natural Science Foundation of China grant (61271171, 61571098), China Postdoctoral Science Foundation (2015M570778), the Fundamental Research Funds for the Central Universities (ZYGX2013J002), Guangdong Science and Technology Project (2012B090400031, 2012B090500003, 2012B091000163), and National Development and Reform Commission Project.enPublisher Copyright: © 2015 IEEE.201510.1109/GLOCOM.2014.741742884964877502
