The paper presents a survey on OpenFlow related technologies that have been proposed as a means for researchers, network service creators, and others to easily design, test, and deploy their innovative ideas in experimental or production networks to accelerate research activities on network technologies. Rather than having programmability within each network node, separated OpenFlow controllers...

Network functions (e.g., firewalls, load balancers, etc.) are traditionally provided by proprietary hardware appliances. These hardware-appliances can be hardwired back to back to form a service chain, which provide services to application layer programs. So, hardware-based functions cannot be provisioned on demand since they are embedded in the network topology making creation, insertion, modi...

Wireless Sensor Network (WSN) is leading to a new paradigm of Internet of Everything (IoE). WSNs have a wide range of applications but are usually deployed in a particular application. However, the future of WSNs lies in the aggregation and allocation of resources, serving diverse applications. WSN virtualization by the middleware is an emerging concept that enables aggregation of multiple inde...

Network hypervisors provide the network virtualization layer for Software Defined Networking (SDN). They enable virtual network (VN) tenants to bring their SDN controllers to program their logical networks individually according to their demands. In order to make use of the high flexibility of virtual SDN networks and to provide high performance, the deployment of the virtualization layer needs...

Three convergent processes are likely to shape the future of internet beyond-5G: The convergence optical and millimeter wave radio networks boost mobile capacity, machine learning solutions communication technologies, virtualized programmable network management mechanisms towards fully integrated autonomic resource management. integration virtualization technologies creates incentive customize ...

In this tutorial paper, we look into the evolution and prospect of network architecture propose a novel conceptual for 6th generation (6G) networks. The proposed has two key elements, i.e., holistic virtualization pervasive artificial intelligence (AI). consists slicing digital twin, from aspects service provision demand, respectively, to incorporate service-centric user-centric networking. int...

Network virtualization supports future Internet environments and cloud computing. Virtualization can mitigate many hardware restrictions and provide variable network topologies to support variable cloud services. Owing to several advantages such as low cost, high flexibility, and better manageability, virtualization has been widely adopted for use in network virtualization platforms. Among the ...

It has been widely accepted that software virtualization has a big negative impact on high-performance computing (HPC) applications performance. This work explores the potential use of Infiniband hardware virtualization in an OpenNebula cloud towards the efficient support of MPI-based workloads. We have implemented, deployed, and tested an Infiniband network on the FermiCloud private IaaS cloud...

The abstraction of the network node functions using virtualization methods introduced an innovative architecture called Network Function Virtualization (NFV). In NFV, every software hosts a service recognized as Virtual (VNF). general, provider creates Service Chain (SFC) for sequence multiple requested VNFs by customers. Although NFV allows more flexible and economical approach, it is prone to...

ion and modularity In the field of the Computer Science, abstraction and modularity are commonly used. The term abstraction indicates the definition of a certain software component specifying only the interface showed to the users. Programmers can therefore make their own design and implementation choices, as long as they respect the external interface. As an example, we can consider the abstra...
