Although virtual organizations and networks have been studied, there is still need for research regarding their inner dynamics and the mechanisms of leadership and governance. This paper investigates micropolitical processes i.e. informal actions of individual actors to gain power and exert influence, which is a well-researched concept in traditional organizations with respect to inter-organiza...

Nonblocking networks are always favored to be used as switching networks whenever possible. There are three types of nonblocking networks, namely rearrangeable nonblocking networks, wide-sense nonblocking networks, and strictly nonblocking networks. Large-scale wide-sense nonblocking networks and strictly nonblocking networks may be infeasible due to their high cost. In contrast, rearrangeable ...

This paper examines the effects of composition, size and structure of virtual networks on the diffusion of information. The research extends the Axelrod cultural model (ACM), an established theory rooted in political science research, to explain information dissemination among social actors in ICT-enabled virtual networks (Axelrod 1997). The investigation is focused on the impact of network str...

Network Virtualization is acclaimed to be a key component for the Future Internet by enabling the coexistence of heterogeneous (virtual) networks on the same physical infrastructure, providing the dynamic creation and support of different networks with different paradigms and mechanisms in the same physical network. A major challenge in the dynamic provision of virtual networks resides on the e...

Face book is virtual and cybernetic network which causes an effective force and among the youth. It shows that if the usage of the face book network increases at home the rate of the interaction and the bounding social capital decreases as well. It also indicates that the effect of face book usage among the young people has increased already. Through a questionnaire by a survey method, more tha...

The multilayer structure of transport networks presents a key challenge in network resource management. In this article we present a virtual network approach to the management of transport network resources. We describe the approach as developed for the management of large-scale ATM networks and discuss the application to the next generation of multilayer transport networks. Virtual Network Res...

Multi-threshold CMOS (MTCMOS) technology is an effective sub-threshold leakage power reduction method in CMOS circuits, which satisfies high-performance and low-power design requirements. The optimization of virtual supply network plays an important role in MTCMOS low-power design. Existing low-power works are mainly on gate level, without any optimization on physical design level, which can le...

ATM supports multiple quality of service classes for different application requirements. A Quality of Service is associated with a virtual path connection. Dynamic reconfiguration can generate an optimal virtual path connection network and maintains sufficient capacity to carry the established calls in progress. We developed a tool to present information specific to the changes of virtual path ...

The MetaCenter is both Czech national Grid and supercomputing infrastructure and a research project focused on sustainable advancement of this infrastructure. We describe a research activity bringing virtual network service to MetaCenter. It covers the reasons for implementing VirtCloud, system for managing virtual networks, expected use-cases, design and implementation constraints and interact...
