Network Function Virtualization (NFV) is a promising technique to greatly improve the effectiveness and flexibility of network services through a process named Service Function Chain (SFC) mapping, with which different network services are deployed over virtualized and shared platforms in data centers. However, such an evolution towards software-defined network functions introduces new challenges...
In these days, a large amount of popular peer-to-peer (also commonly known as P2P) applications, especially in the live streaming domain, are operating in Internet. One of the keys to success of such an application is the mutual cooperation among the participants (i.e., peers) in that application. However, presence of selfish peers (also commonly known as free riders) affects the performance of the...
In a cloud computing environment, it is necessary to simultaneously allocate both processing ability and network bandwidth needed to access it. The authors proposed the joint multiple resource allocation method in a cloud computing environment that consists of multiple data centers and each data center provides the different network delay. It is also highly likely that each data center would provide...
