Network Function Virtualization allows the provisioning and composition of on-demand network function chains tailored to an application or a service. Repeatable compliance tests and performance comparison of network functions and the whole function chains are required for virtual network function manufacturers and telecommunication operators. In this paper, we propose and develop SFCPerf, a fra...

The use of computing resources on network is becoming active in the Internet and private networks. OpenFlow/Software-Defined Networking (SDN) is drawing attention as a method to control network virtualization for the cloud computing services and other carrier services. This paper introduces examples of OpenFlow/SDN technologies applied to commercial cloud services. Various activities to expand ...

Viator, the Wandering Network approach, defines a new type of communications architecture chracterized by: • flexible, multi-modal specialization of network nodes as virtual subnetworks; • mobility and virtualization of the net functions in hardware und software; • self-organizing multi-feedback topology-on-demand. Network elemens can contain several exchangeable modules capable of executing di...

Network Function Virtualization (NFV) has recently received significant attention as an innovative way of deploying network services. By decoupling network functions from the physical equipment on which they run, NFV has been proposed as passage towards service agility, better time-tomarket, and reduced Capital Expenses (CAPEX) and Operating Expenses (OPEX). One of the main selling points of NF...

A vision of photonic network in 2020 is presented, which envisages “smart photonic cloud” in the Big Data era. The smart photonic cloud is referred to as an atmosphere which serves as a universal infrastructure, providing with connectivities to machine-to-machine communications such as networked high-performance computing and intraand inter data center networks. To cope with strong demands for ...

Network virtualization is a concept where physical resources are used to create virtual resources that are combined to form virtual networks. As one of the key enablers of the future Internet, network virtualization solves a number of issues associated with today’s networks. Concepts of network virtualization that are not restricted to virtualization technology, termed as overall concepts that ...

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 their virtualization techniques, achieved performance in virtualizing computational resources and appropriateness for usage in a virtual n...

Network services are an important component of the Internet, which are used to expand network functions for third-party developers. Network function virtualization (NFV) can improve the speed and flexibility of network service deployment. However, with the evolution of the network, network service layout may become inefficient. Regarding this problem, this paper proposes a service chain migrati...

In 2013, the IEEE Future Directions Committee (FDC) formed an SDN work group to explore the amount of interest in forming an IEEE Software-Defined Network (SDN) Community. To this end, a Workshop on “SDN for Future Networks and Services” (SDN4FNS’13) was organized in Trento, Italy (Nov. 11-13 2013). Following the results of the workshop, in this paper, we have further analyzed scenarios, prior-...
