摘　　要：With the emergence of high-bitrate applications, cross stratum optimization （CSO） attracts the interest of network operators because of its application in the joint optimization of optical networks and application stratum resources. Given the large-scale growth and high complexity of optical networks, achieving a more effective, accurate, and practical CSO becomes an important research focus. In this letter, we present a CSO-oriented, unified control architecture for OpenFlow-enabled triple-M optical networks. A novel dynamic global load balancing （DGLB） strategy with dynamic resource rating for CSO is presented based on the proposed architecture. The DGLB strategy is then compared with four other strategies by conducting experiments on a SOFT-based testbed with 1000 virtual nodes.With the emergence of high-bitrate applications, cross stratum optimization （CSO） attracts the interest of network operators because of its application in the joint optimization of optical networks and application stratum resources.
