Efficient Approach to Topology based Hybrid Software Defined Networking

Abstract

Many significant network and cloud service providers, including Tech Giants, are now using newlineSoftware-Defined Networks (SDN). The time, money, and talent required to replace the mature newlineand well-established legacy networking paradigm with a future networking paradigm will be newlineenormous. As a result, many businesses are unable to invest in it. A hybrid network system (also newlineknown as Hybrid SDN (hSDN)) is a workable compromise since it uses SDN capabilities while newlineacknowledging the value of traditional network architecture. Many businesses and organizations newlineare now considering hSDN as an effective networking option. As a result, there has been a dramatic newlineincrease in research on the subject. The results of a comprehensive, up-to-date poll that examines newlinehSDN from various angles are provided. newlineSoftware Defined Networking (SDN) allows communication networks to be operated and newlinemanaged by separating the control and forwarding planes. Replacing old network switches with newlineSDN switches is expensive, and pure SDN is limited in its capacity to scale and be durable. As a newlinenew emerging technology, hybrid SDN aims to alleviate some of the shortcomings of SDN by newlineconnecting legacy switches with SDN switches. We employ two open source controllers, POX and newlineRyu, to evaluate the performance of these two controllers. To get the findings, we simulate newlinedifferent QoS needs in each topology in Mininet. newlineSDN is on the verge of reaching the point where it is widely accepted. An increase in SDN adoption newlineis being examined because it is being studied as a feasible solution for creating hybrid SDN newlinenetworks. SDN-enabled and conventional switches must be integrated into a hybrid SDN network newlineto allocate bandwidth. Spanning Tree Protocol (STP) avoids the layer 2 switch network loop by newlinecontinuously monitoring the network system, tracking down all links, and obstructing those that newlineshould not be there. Bridge loops will occur when there is a redundant Layer2 path between two newlinepoints. As a general rule, it switches forward broadcast/multicast traff
