Complexity and flexibility are the main problems that will be faced in the world of the future network. To be able to answer these problems, a method called Software Defined Network (SDN) is being developed. The SDN concept is to separate the network's controller and forwarding plane of the hardware. In this research, SDN component, white box switch was built. To test its performance, RTT and throughput of some configuration were measured. The result is compared to conventional switch, which is Cisco Catalyst 2950. White Box Switch was created of a computer with 2.50 GHz processor and 32 GBytes memory. The result shows that performance of Cisco Catalyst 2950 is superior to white box switch because of its ASIC that allow it to forward data in hardware. Furthermore minimum specification of white box switch can be calculated, that is 1.225 GHz processor and 1 GBytes memory. To get the best performance, we can use single-board computer to be used as white box switch. Single-board computer contains all of its hardware in a single-board and it will give best performance of a computer.

“…Finally, using the two-way UDP with an embedded timestamp of connected hosts to detect the Round-trip Delay Time (RTD) or One-way Delay (OWD). Like the TCP timestamp option, it supplies an accurate latency but requires a customised benchmark which can test only the latency of UDP packets [9].…”

Developers of Software Defined Network (SDN) faces a lack of or difficulty in getting a physical environment to test their inventions and developments. That drives them to use a virtual environment for their experiments. This work addresses the differences between the SDN virtual environment and physical SDN switches, which leads to equip a more realistic SDN virtual environment. Consequently, this paper presents a precise performance evaluation and comparison of off-the-shelf SDN devices, HP Aruba 3810M, with Open Virtual Switch (OVS) inside Mininet emulator. This work examines the variability of the path delay, throughput, packet losses and jitter of SDN in a different windows size of the packets and network background loads. Our conducted experiments consider a number of protocols such as ICMP, TCP and UDP. In order to evaluate the network latency accurately, a new asynchronous latency measurement technique is proposed. The developed technique shows more precise results in comparison to other techniques. Furthermore, the work focuses on extracting the flow-setup latency, caused by the external SDN controller when setting flow rules into the switch. The comparison of results shows a dissimilarity in the behaviour of SDN hardware and the Mininet emulator. The SDN hardware exposed higher latency and flowsetup time due to extra resources of delay, which the emulator does not possess.

“…To the best of our knowledge, not much work has been reported about the actual performance limits of network virtualization in OpenStack cloud infrastructures under the NFV scenario. Some authors assessed the performance of Linux-based virtual switching [10,11], while others investigated network performance in public cloud services [12]. Solutions for low-latency SDN implementation on highperformance cloud platforms have also been developed [13].…”

The emerging Network Function Virtualization (NFV) paradigm, coupled with the highly flexible and programmatic control of network devices offered by Software Defined Networking solutions, enables unprecedented levels of network virtualization that will definitely change the shape of future network architectures, where legacy telco central offices will be replaced by cloud data centers located at the edge. On the one hand, this software-centric evolution of telecommunications will allow network operators to take advantage of the increased flexibility and reduced deployment costs typical of cloud computing. On the other hand, it will pose a number of challenges in terms of virtual network performance and customer isolation. This paper intends to provide some insights on how an open-source cloud computing platform such as OpenStack implements multitenant network virtualization and how it can be used to deploy NFV, focusing in particular on packet forwarding performance issues. To this purpose, a set of experiments is presented that refer to a number of scenarios inspired by the cloud computing and NFV paradigms, considering both single tenant and multitenant scenarios. From the results of the evaluation it is possible to highlight potentials and limitations of running NFV on OpenStack.
