We present a micro edge cloud (MEC) architecture for resource optimization and implement the virtualization of resource. The virtualization solution is demonstrated to verify the overall feasibility and efficiency.
This paper proposes a flexible intelligence cloud-based radio over optical fiber networks by designing and using a reconfigurable wavelength-frequency selective switch. Numerical results demonstrate the feasibility of the proposed architecture and excellent spectrum effectiveness.
Driven by ubiquitous cloud computing application, datacenters have been deployed widely as important IT resources. However, some disadvantages are challenging the cloud computing because the datacenters are deployed concentrated and remotely, which cannot guarantee the quality of experience (QoE) for the customers, such as the latency, bandwidth, energy consumption, and network cost. Fog computing...
This paper addresses the minimum network cost problem for survivable virtual optical network mapping in flexible bandwidth optical networks. For each virtual link, we provide dedicated-path protection, i.e., primary path and backup path, to guarantee high survivability on the physical network. To simplify the virtual links mapping, an extended auxiliary graph is constructed by coordinating the virtual...
We define k-content connectivity as the reachability of at least one content from any point of a data center network under concurrent k-1 failures. A flexible content placement algorithm is proposed to achieve k-content connectivity.
