Reconfigurable Fundamental Information Communication Network achieves optimum transmission quality for special services by establishing Omnibus Circuits. Due to the support of network virtualization in this architecture, optimum efficiency of Omnibus Circuits can be promoted by mapping services of the same type to one group of substrate devices. For this requirement, this paper designs a virtual network mapping algorithm for service aggregation. Because this algorithm has a comprehensive consideration of surplus resources and situation of mapped services, the services tend to be mapped on the substrate devices which host numerous services of the same type. Furthermore, a node selection strategy with hop constraint is proposed for reducing the running time of the algorithm. Simulation experiments show that this algorithm not only has a better performance in the acceptance ratio and the resource occupancy rate, but also substantially increases the degree of service aggregation.
