In the practical crowdsourcing systems, there exist many cooperative tasks, each of which requires a group of users to perform together, such as finding the shortest multi-hop path or obtaining the media resources from a set of hosts. In this paper, we tackle the problem of how to truthfully and fairly schedule or allocate sufficient users who join mobile crowd-sourcing applications with their smartphones...
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.
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...
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...
A dual routing engine-based routing scheme for large scale optical networks is proposed in this paper. An interpreter-based modeling of the group engine is discussed and a preliminary routing strategy is designed with consideration of scalability and flexibility.
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...
An application-driven network resource scheduling scheme that support parallel lightpaths is presented to solve the optical network resource dynamic allocation for real-time media service. The resource scheduling scheme combines grid network service and optical intelligent control plane to implement lightpath connection driven by grid application, even parallel channels for media stream. Optical resource...
A novel cloud computing architecture over optical networks is proposed based on the service plane. An experiment of resources dynamic co-schedule is deployed on our AMSON testbed and the result of it demonstrates the validity of the architecture we proposed.
This paper investigates the problem how to schedule optical network resource in distributed lambda grid network. A novel scheme to share lightpath is proposed to deal with the resource allocation and sharing under the condition of multi-user and multi-task, which provide a new realization way of parallel processing in heterogeneous resource environment, and two kinds of sharing transfer mode are put...
In this paper we present an approach for online traffic classification based on the statistical analysis of protocol behaviour at IP level. Then we use the statistics of protocol attribute and Bayesian network method to build a classifier,which can classify unknown flows dynamically as packets pass through the classifier, deciding if a flow belongs to a given application. Distinct from other methods,...
An on-demand multi-user lightpath sharing solution supporting multi-path parallel transport is experimentally demonstrated in GMPLS-enabled lambda grid testbed for the first time. Experimental results show that end-to-end lightpath can be simultaneously employed by two or more grid users according to their dynamic requests.
