“…The work from home policy was greatly facilitated by commercial VPNs as damage control practices. This technology is also a favourite of SPs who lease dedicated lines but make the most of it by sharing [10] those lines via isolated VPNs to customers. This virtualisation has been a constant improvement on security, isolation, stability, and resource management.…”

In recent years, network virtualisation has been of great interest to researchers, being a relatively new and major paradigm in networking. This has been reflected in the IT industry where many virtualisation solutions are being marketed as revolutionary and purchased by enterprises to exploit these promised performances. Adversely, there are certain drawbacks like security, isolation and others that have conceded the network virtualisation. In this study, an investigation of the different state-of-the-art virtualisation technologies, their issues and challenges are addressed and besides, a guideline for a quintessential Network Virtualisation Environment (NVE) is been proposed. A systematic review was effectuated on selectively picked research papers and technical reports. Moreover a comparative study is performed on different Network Virtualisation technologies which include features like security, isolation, stability, convergence, outlay, scalability, robustness, manageability, resource management, programmability, flexibility, heterogeneity, legacy Support, and ease of deployment. The virtualisation technologies comprise Virtual Private Network (VPN), Virtual Local Area Network (VLAN), Virtual Extensible Local Area Network (VXLAN), Software Defined Networking (SDN) and Network Function Virtualisation (NFV). Conclusively the results exhibited the disparity as to the gaps of creating an ideal network virtualisation model which can be circumvented using these as a benchmark.

“…Two heuristics for resource allocation in network virtualization are proposed in Amri and Meddeb,21 which are load sharing on multiple paths and traffic concentration on one path. Simulation results show that the resource utilization has an impact on the performance.…”

Network virtualization enables service providers to instantiate virtual networks on a common physical infrastructure. Virtual networks are then allocated to clients in order to deploy or test their services. Thus, clients do not know how their traffic is routed, which server is responding, and which path is crossed. Service providers who own the physical infrastructure aim to share the load among multiple servers for traffic routing. However, those who do not own the infrastructure and want to lease it essay to concentrate all the traffic on one server and exactly the closest server. In this paper, we model the problems of load sharing on multiple servers and traffic concentration on one server as two mathematical programs. The objective functions correspond to service providers' aims under a delay constraint based on the M/D/1/N queue's mean sojourn time's formula. Due to its hardness, we provide an approximation of the delay constraint at low and medium traffic intensities. The approximation is analytically proved by the Taylor series development at a chosen point. Finally, through simulation and analytical models, we compare the performance of programs' optimal solutions. We notice that load sharing decreases the packet loss and jitter values. However, traffic concentration reduces the latency.
