SDN and IBN: Network Design, Cost Reduction, Security, and Automation

This report provides an overview of Software Defined Networks (SDN) and Intent Based Networks (IBN), exploring how they can be combined to design and manage networks efficiently, especially in virtualized and cloud computing environments. The report begins by introducing the concepts of SDN and IBN, highlighting their roles in automating network monitoring and administration. It then presents a cost analysis for an organization's IT infrastructure upgrade, including hardware, software, and licensing costs, to demonstrate the potential for cost reduction. The core of the report delves into the architectures and key features of SDN and IBN, such as centralized control, programmability, automation, and the ability to translate business intentions into network configurations. The report also discusses the benefits of integrating these technologies, including improved performance, enhanced security, and more effective management of network resources. Finally, the report references relevant sources on the topics of SDN and IBN.

ABSTRACT
SDN (Software defined network) and IBN (Intent based network) both will help to design the
network that will automatically monitor the network as well as administrated task. Combining
both software defined network and intent based network on virtualization and cloud computing
will provide a cost effective network, high performance, managing the network assets and high
security on network.
INTRODUCTION ABOUT THE ORGANIZATION
Organization currently has nearly 2000 desktop computer with Microsoft windows operating
system and wants to change them into Dell Optiplex series with Intel Core i5 processor on
windows 10 operating system, 8GB DDR4 RAM, and 256GB of ROM. Each users on the
organization can access on their company network by using VPN software so they can access
using their phones and iPads. Rough estimate for their entire work will be as follows.
S.No Items Cost
1 PC each $1250.00 2000*1250 $2500000.00
2 License $150.00(Office) 2000*150 $300000.00
3 Database with server (10) $2159.00 10*2159.00 $21580.00
4 Server (20) $ 3000.00 20*3000 $60000.00
5 Network device total cost $3000000.00 $750000.00 (Yearly)
6 Security hardware and software $2000000.00 (Yearly)
Total cost $5631580.00
INTRODUCTION TO SOFTWARE DEFINED NETWORK
Software defined networking is a method for developing network architecture that will allow the
network to control centrally by using programmed software application. This helps to manage
and operates the network effectively. This provides effective network architecture by providing
automated, on-demand application transfer and flexibility at scale.

Infrastructure Layer
SDN Architecture
Directly programmable
All the network control is directly programmable as it is decoupled from forwarding functions.
Agile
All the controls are shortly abstracted so that by forwarding this can help to dynamically monitor
the administrator task to adjust the traffic flow on the network in order to meet the changing
needs.
Centrally managed
The centralized based software SDN (Software defined network) controls and maintains the
overall view of the network.
Programmatically configured
Business Application
Network Service
Network Device
API

SDN allows the managers on the network to configure, manage, secure and optimize the network
resources rapidly dynamically using automated SDN software.
Open source
Open standards based implementation on Software Defined Network will simplifies the design
and operation on network but the instructions delivered by SDN will control rather than multiple,
protocols and vendor specific.
INTRODUCTION TO INTENT BASED NETWORK
Intent based network is 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.
Intent based network has four key things
Translation and Validation
The framework takes a larger amount business approach (what) as 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/Remediation
The 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 wanted aim isn't met.
