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.
We present a cloud resources integrated provisioning architecture utilizing coordinated virtualization of distributed datacenters and operator's multi-domain software define optical network. The overall feasibility and efficiency of two proposed virtual network composition schemes are investigated on our testbed.
We demonstrate the disaster resilience of electric power applications for software defined disaster recovery center networking (SD-DRCN) based on elastic optical network. The overall feasibility and performances of the architecture are verified in our study.
Moving from dynamic lighptpath provisioning to virtual network provisioning, Optical as a Service (OaaS) is developing rapidly driven by data center application, which could be mainly enabled by Software Defined Networking (SDN).
Due to the high burstiness and high-bandwidth characteristics of the services, optical interconnect in intra-datacenter networks has attracted much attention. Many datacenter applications in the environment require lower delay and higher availability with the end-to-end guaranteed quality of service. In this paper, we propose a novel time-aware software defined networking (TaSDN) architecture for...
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.
Nowadays, most service providers offer their services and support their applications through federated sets of data centers that need to be interconnected using high-capacity telecom transport networks. To provide such high-capacity network channels, data center interconnection is typically based on IPand optical transport networks that ensure certain end-to-end connectivity performance guarantees...
With network resource virtualization and the rise of user experience demand, it is needed to design a system architecture based on the cooperation of multiple virtual machines, which can detect customers' business needs prospectively and manage network resource legitimately. It is also needed to design a highly reliable virtual machine resource unified dispatch program, which detects customers' business...
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.
Different from general multi-failure, group-failure in cross-layer intelligent optical networks has the characteristic of cluster. Because multi-failure may occur due to single failure, it is more harmful for multi-failure than single failure. The original survivability with regards to multiple single failures is not suitable for group-failure based cross-layer survivability research. Group-failure...
With the development of large-scale, multi-region and multi-layer networks, policy and constraint-based path computation is more and more complicated and dynamic routing becomes one of the key issues in GMPLS/ASON networks. Then a routing architecture named PCE is proposed to resolve the aforementioned complicated routing problem. However, as the huge bandwidth requirement emerges, capacity of Tbit/s...
