在多控制器 SDN 虚拟化环境中,以最小化控制通路平均时延、控制器负载失衡度和映射开销为目标,分别建立多控制器部署问题和虚拟SDN映射问题的数学模型,提出一种多控制器条件下区分QoS的虚拟SDN映射方法。仿真结果表明该方法能够满足不同用户对虚拟 SDN 服务质量的需求,保持多控制器的负载均衡,提高了映射成功率和收益开销比。
In SDN virtua1ization environment under mu1tip1e contro11ers,with the goa1 of minimum the mean de1ay between contro1 paths,the 1oad imba1ance of contro11ers,and the cost of embedding,mathematica1 mode1s of the contro11er p1acement and the virtua1 SDN embedding prob1em were bui1t,and a virtua1 SDN embedding method with differentiated QoS under mu1tip1e contro11ers was proposed.The simu1ation resu1ts show that the proposed a1gorithm can satisfy various virtua1 networks QoS for users,keep 1oad ba1ance between contro11ers and increase the acceptance ratio and the revenue/cost ratio.
