ABSTRACTSDN (Software defined network) and IBN (Intent based network) both will help to design thenetwork that will automatically monitor the network as well as administrated task. Combiningboth software-defined network and intent-based network on virtualization and cloud computingwill provide a cost-effective network, high performance, managing the network assets and highsecurity on network. This report has the details about the Software Defined Network, relationbetween SDN and virtualization, and how this SDN will reduce the cost and time of the existingsystem.INTRODUCTION ABOUT THE ORGANIZATIONOrganization currently has nearly 2000 desktop computer with Microsoft Windows operatingsystem and wants to change them into Dell Optiplex series with Intel Core i5 processor onWindows 10 operating system, 8GB DDR4 RAM, and 256GB of ROM. Each users on theorganization can access on their company network by using VPN software so they can accessusing their phones and iPads. Rough estimate for their entire work will be as follows.S.NoItems Cost1PC each $1250.00 2000*1250 $2500000.002License $150.00(Office) 2000*150$300000.003Database with server (10) $2159.00 10*2159.00$21580.004Server (20) $ 3000.00 20*3000 $60000.005Network device total cost $3000000.00$750000.00 (Yearly)6Security hardware and software$2000000.00 (Yearly) Total cost $5631580.00INTRODUCTION TO SOFTWARE DEFINED NETWORKSoftware-defined networking is a method for developing network architecture that will allow thenetwork to control centrally by using programmed software application. This helps to manageand operates the network effectively. This provides an effective network architecture byproviding automated, on-demand application transfer and flexibility at scale.Application LayerBusiness ApplicationAPI

Control LayerSDNControlSoftware Infrastructure LayerSDN ArchitectureDirectly programmableAll the network control is directly programmable as it is decoupled from forwarding functions.AgileAll the controls are shortly abstracted so that by forwarding this can help to dynamically monitorthe administrator task to adjust the traffic flow on the network in order to meet the changingneeds.Centrally managedThe centralized based software SDN (Software defined network) controls and maintains theoverall view of the network.Programmatically configuredSDN allows the managers on the network to configure, manage, secure and optimize the networkresources rapidly dynamically using automated SDN software.Open source Open standards-based implementation on Software Defined Network will simplify the designand operation on the network but the instructions delivered by SDN will control rather thanmultiple, protocols and vendor specific.INTRODUCTION TO INTENT BASED NETWORKIntent-based network is a network software that helps to plan, create, design and deploy on the network to enhance the network accessibility and quickness. This will monitor an administrative task automatically among the network. This provides a self-managing network.Network ServiceNetwork Device

Intent-based network has four key things Translation and ValidationThe framework takes a larger amount business approach (what) as a contribution from end clients and believers it to the fundamental system design (how). The framework at that point produces and approves the subsequent outline and design for accuracy. Robotized Implementation The framework can arrange the proper system changes (how) crosswise over existing system foundation. This is regularly done by means of system computerization as well as system coordination. Consciousness of Network State The framework ingests constant system status for frameworks under its regulatory control and is convention and transport-rationalist. Confirmation and Dynamic Optimization/RemediationThe framework persistently approves (continuously / streamlined) that the first business goal of the framework is being met, and can take restorative activities, for example, blocking movement, adjusting system limit or telling when the wanted aim isn't met.IntentHowVIRTUALIZATION ON DESKTOPVirtualization is a service that provides an access to use desktop from backend infrastructure tothe front as this will provide the access to thin or small clients to use their desktop thus willreduce the cost and time. NetworkOrchestration MachineLearning

For connecting virtualization on the desktop a client has to make their connection with a brokerwho act as a middleware to manage the request from the client and make a connection to theavailable desktop (virtual system). Desktop virtualization is not a server-based computing as itdoes not support an equal range of accessing hardware as desktop virtualization. PROS AND CONS OF VIRTUALIZATION ON DESKTOPPros of virtualization on the desktopWork as sandboxIndependent in accessing hardware, Operating systemQuick recoveryEasy and streamline backupTransfer data easilyReduce the access to hardwareSimultaneously run on different and multiple operating systemsLess cost and time consumingHigh SecurityCons of virtualization on the desktopMinimum efficientNot a stable performanceThe latency of virtual diskSome security issuesCompatibility issueRELATION BETWEEN SDN AND IBN It has been many years ago Software Define Network is used for administrating thenetwork. It has many advantages in its applications. In general, it is used for managing,monitoring helps during the breakdown of networks without the need for hardware, routers,switches and other physical devices. These networks are not often available with the networkfunctions but they can be found in virtualization technology. Both SDN and the virtualizationtechnology are related to each other with different goals. They help to enable the networkmanagers and the administrator to customize and configure the network functions and their
