简介：为了提高OpenFlow的通讯质量，控制了所有光的网络，光signal-to-noise比率全面了解(OSNR-CA)为基于的lightpath控制建模计划被建议。这条途径把主要物理层的光缺陷转变成OSNR价值，并且沿着lightpath考虑光信号的这全面OSNR值，当用开流动的协议为连接请求建立lightpath时。而且，建议计划做在每个节点监视功能的OSNR的完整的优点，并且由扩大OpenFlow协议的消息根据comprehensive-OSNR价值分配lightpath，以便保证lightpath的可靠建立。模拟结果证明建议计划以包损失率和lightpath建立时间有更好的性能。
