Distributed Virtual Network Embedding for Software-Defined Networks Using Multiagent Systems

Virtual Network Embedding (VNE), which provides methods to assign multiple Networks (VN) a single physical Substrate (SN), is an important task in network virtualization. The main problem VNE the efficiency of assigning customers’ virtual requests substrate network. This known be Non-deterministic Polynomial-time hard (NP-hard) and heuristic solutions have been developed solve this kind problem. current trend toward Software-Defined Networking (SDN) has allowed new possibilities embedding. In work, we propose distributed embedding for SDNs called DVSDNE using multi-agent systems. framework could used run centralized algorithm manner scale these algorithms with respect size. uses agents spread load across Our simulation results show effectiveness proposed algorithm. Results that improves execution time large networks, while such as acceptance ratio, revenue cost average latency controller, maximum controller remain comparable.
