- Resource allocation and deployment of network Service Function Chain (SFC) is a vital problem of 5G network virtualization. By introducing SDN and NFV technology, the core network is reclassified as the control layer, forwarding layer and scheduling layer. A Virtual Network Embedding algorithm based on subgraph isomorphism (VNE-MSI) is proposed to allocate resource of each layer in isolated way. The proposed heuristic algorithm collaboratively maps decoupling Service Function Chain with backtracking strategy. Collaborative search strategy is designed according to the characters of virtual Evolved Packet Core. The experimental evaluations show that this method especially performs well in acceptance ratio and revenue-to-cost ratio.
