Flowvisor: A network virtualization layer
free download

Network virtualization has long been a goal of of the network research community. With it, multiple isolated logical networks each with potentially different addressing and forwarding mechanisms can share the same physical infrastructure. Typically this is achieved by taking

Challenges in resource allocation in network virtualization
free download

Virtualization promises to overcome the weaknesses of the current Internet and to act as a torch bearer technology for enabling innovative network architectures. However, a fundamental problem in instantiation of Virtual Networks (VNs) is an optimal allocation of

Implementing network virtualization for a future internet

Network virtualization system suite: Experimental network virtualization platform
free download

Network virtualization arises as a potential solution for addressing the current IP limitations through a non-disruptive route, by letting multiple networks, running different protocols, to coexist and share the same infrastructure in an independent way. The purpose of this paper

Software-defined network virtualization with flown
free download

Network virtualization enables multiple control planes to run concurrently and each affect only its portion of the data plane state and configuration. With the standardization of the interface between the control plane and data plane, software defined networking is a natural

Designing modular overlay solutions for network virtualization
free download

Networking is currently facing important challenges arising from the advent of virtualization and cloud computing. Broad acceptance of these advanced technologies has raised new networking requirements related to the complex configuration, management and control

Evaluating Xen, VMware, and OpenVZ virtualization platforms for network virtualization
free download

Network virtualization is a technique that allows having multiple concurrent isolated networks sharing physical network resources. This work analyzes the main available virtualization platforms, Xen, OpenVZ, and VMware, for network virtualization . We compare

Analysis on Quality of Service Provisioning for Communication Services in Network Virtualization .
free download

The Internet is currently facing many new chal-lenges that require fundamental changes in network architecture and service models. However the current Internet lacks the flexibility to adopt innovations in network architecture and service provisioning. To fend off this

Europa: Efficient User Mode Packet Forwarding in Network Virtualization .
free download

Network virtualization provides the ability to run concurrent virtual networks over a shared substrate. However, it is challenging to design such a platform to host multiple heterogeneous and often highly customized virtual networks. Not only minimal interference

Optimization of Wireless Disaster Network through Network Virtualization .

Natural disasters reported to have occurred increased dramatically over the second half of the 20th century. Floods, earthquakes, tsunamis and storms have appeared worldwide with catastrophic consequences. Right after the catastrophic events, the demand for

The 2013 Guide to Network Virtualization and SDN
free download

Over the last year, the hottest topics in networking have been Network Virtualization (NV) and Software Defined Networking (SDN). There is, however, considerable confusion amongst enterprise IT organizations relative to these topics. There are many sources of that

OpenFlow network virtualization with FlowVisor
free download

OpenFlow networks became popular in the past years for researchers and commercial companies. OpenFlow essentially separates the control and data plane of a switch. The control plane is moved to an external controller. Network researchers have wanted to

Survey on Network Virtualization Using OpenFlow: Taxonomy, Opportunities, and Open Issues.
free download

The popularity of network virtualization has recently regained considerable momentum because of the emergence of OpenFlow technology. It is essentially decouples a data plane from a control plane and promotes hardware programmability. Subsequently, OpenFlow
