Performance analysis of white box switch on Software Defined Networking using open vSwitch

Abstract

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.

Predictable Bandwidth Slicing with Open vSwitch

“…He et al [14] evaluate a software switch bandwidth slicing mechanism; however, their tests were performed in simple scenarios and their results are presented without a thorough analysis of the latency values. The same shortcoming is exhibited in [10]- [13] in terms of latency evaluation: their models of packet latency are for simple, synthetic testing scenarios. The latency of a single flow has been evaluated in [10]- [12], while [13] only evaluates the latency of a single packet.…”

“…Although one of the main benefits of software switches when compared to traditional hardware switches is the high degree of flexibility offered, there remains areas of study that have largely been neglected in existing analyses. Specifically, existing studies overwhelmingly focus on the switches' maximum throughput capabilities [6]- [8] or latency measurements in best-case, non-realistic scenarios [1], [2], [9]- [13]. These studies are important to understand the performance limitations of software switches, but they provide very little to characterize performance in real-world scenarios.…”

A Survey on Edge Computing Systems and Tools

“…Fig. 14 shows the hardware [34] is a component of SDN switch, which is responsible to regulate the flow of data according to SDN controller. These commodity servers provide computing, storage resources, and the fabric of switches are used to build the network.…”

Simulação de Ambientes de Redes Utilizando a Testbed FIBRE - Aplicações na Pesquisa e no Ensino

“…Para poder funcionar como deve ser, as Whitebox requerem um software de comutação virtual que possa ser incorporado diretamente. Além disso, as Whitebox também devem receber ordens do controlador SDN [Manggala et al 2015] para poderem funcionar. Essaé a diferença mais fundamental entre as Whitebox e os switchs convencionais.…”
