Computing and storage resources are two kinds of important resources for cloud computing, which are provided by different datacenters distributed at different positions. Then, datacenter networking is necessary for high efficient resource provisioning. Flexi-grid optical network is considered as a promising technology for datacenter networking because of its high spectrum efficiency and fine switching...
We present a data center service localization architecture based on virtual resource migration in software defined elastic optical network. The overall feasibility and efficiency of the proposed architecture are experimentally verified on our 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.
