We present a multi-stratum resources integration architecture for data center application with flow estimation based on multiple OpenFlow controllers cooperation. The overall feasibility and efficiency of the proposed architecture are experimentally verified on our testbed.
We present a novel architecture for Cross Stratum Optimization of application and network resource with OpenFlow protocol. Several global load balancing strategies are proposed and demonstrated by experiments on Optical as a Service (OaaS) testbed.
An IA-RWA computation with QoT compensation based on double Cooperating PCEs is presented and extended AMSON testbed is verified. Two kinds of IA-RWA computation with QoT compensation strategies including Cooperating PCEs based and RSVP based strategies are demonstrated and compared.
A novel global quality of transmission (QoT) optimization scheme is proposed for GMPLS-based reconfigurable transparent optical networks. By perceiving and controlling the transmission impairments and state of tunable compensators, dynamic QoT optimization is implemented on the fly. Simulation results show that, the proposed QoT optimization can avoid unnecessary compensator adjustment and lower operating...
A network flow decomposition algorithm is proposed to achieve a lower block probability. The algorithm is designed to achieve a flow balance between domains, advertising TE information that is necessary for network to build a TED (Traffic Engineer Database) to calculate a suitable route for each service request for network optimization.
