InstructionsSoftware-defined networking (SDN) and intent-based networking (IBN) offer an ability to revolutionize the modern network architecture. Both of these concepts are relatively new, and your chief technology officer (CTO) has only heard them in passing. In fact, she pawned them off as the new “marketing fad” dressed up as a new concept. Since you have researched both technologies, you understand this is not a fad. When used in combination with virtualization and cloud computing, you know SDN and IBN could revolutionize how the organization operates, providing for reduced costs, efficiency, better management of the network assets, and security. However, you need to develop a white paper for the Caduceus CTO to highlight these benefits. Given the CTO has only heard the term in passing, you must describe in this white paper, the SDN and IBN concepts, their benefits, and what it would take for the organization to implement.Writing Your PaperAfter you introduce yourself to your team and brainstorm ideas for this assignment, refer to the SDN and IBN Assignment Resources for more details about Caduceus and download the assignment template.In your white paper, use additional sources of information but also describe the concept in layman’s terms. Use visuals where appropriate. Describe how an SDN/IBN architecture would look different than network architectures we have traditionally deployed. Compare and contrast the network architectures and discuss the pros and cons of each.The paper should include the following sections:introduction to software-defined networking (SDN) (discussed in Week 3)introduction to intent-based networking (IBN) (discussed in Week 4)discussion on how virtualizing the desktop and now back-end infrastructure are complementary and relateddiscussion of how SDN and IBN are relatedSubmitting Your WorkDownload the assignment template cover page and complete your white paper.How Will My Work Be Evaluated?The following evaluation criteria aligned to the competencies will be used to grade your assignment:1.1.1: Articulate the main idea and purpose of a communication.1.1.2: Support the main idea and purpose of a communication.1.1.3: Present ideas in a clear, logical order appropriate to the task.1.1.4: Explain the relationship between the ideas presented to enhance clarity and comprehension. 1.3.3: Integrate appropriate credible sources to illustrate and validate ideas.1.4.1: Produce grammatically correct material in standard academic English that supports the communication. 1.4.3: Write concise and logical sentences in standard academic English that clarify relationships among concepts and ideas. 2.3.1: State conclusions or solutions clearly and precisely.10.1.3: Define the specifications of required technologies.13.2.1: Evaluate vendor recommendations in the context of organization requirements.When complete, export your file as a PDF

SDN & IBN Assignment
CMIT 495: Current Trends and Projects in Computer Networks and Security
This white paper should include the following sections:
• introduction to software-defined networking (SDN) (discussed in
Week 3)
• introduction to intent-based networking (IBN) (discussed in Week 4)
• discussion on how virtualizing the desktop and now back-end
infrastructure are complementary and related
• discussion of how SDN and IBN are related
Company Highlights

The organization currently maintains 2,000 Microsoft Windows desktop computers
for the workforce. As you recall, these desktop computers were about to be
refreshed. The organization is currently considering the Dell Optiplex series.
Specifically, each computer would have a Intel Core i5 processor, run Microsoft
Windows 10, contain 8GB DDR4 RAM, and have a 256GB solid state drive. The
rough estimate for each PC is $1,250, which equates to a $2,500,000 upgrade cost
to the organization.

Microsoft Office runs on each of these computers. The license fee for each
computer is $150, which equates to a $300,000 outlay. The organization typically
upgrades all PCs with the latest version of Microsoft Office when it is released.

The organization used multiples instances of Oracle Database. These databases
are distributed across 10 Dell PowerEdge servers. These servers cost a minimum of
$2,159 each, for a total cost of $21,580.

The organization maintains an additional 20 Dell PowerEdge servers for a variety of
reasons to include email, file backup, remote access, etc. The total cost to refresh
each of these servers is $3,000 for a total cost of $60,000.

The organization maintains various networking devices. The total cost of this
equipment is $3,000,000 and yearly refresh costs are $750,000.

The organization maintains a suite of network security hardware and software
solutions. They include a DMZ configuration, multiple firewalls, VPN hardware,
antivirus solutions, intrusion detection and protection devices, and log management
solutions. The total yearly hardware and software costs for the organization
cybersecurity efforts are $2,000,000.

The organization also allows users to access the network via their company-issued
Android phones, or iPads. Employees receive a mobile device with VPN software
installed so that they may remotely access company systems when they are at
home, or traveling.

Because this is a notional example and assignment, you may make further
assumptions about the organization IT environment. There is no need to ask your
instructor for permission. Simply make explicit your assumptions in the white paper.
For example, you are free to assume the number of IT professionals, their
specialties, and more importantly the cost to run the IT department.
