What’s the most any of your networking projects ever went over budget? A few thousand dollars? Tens of thousands? Millions?
What about $1.19 billion?
That’s how much a major networking project went over its originally proposed budget of $6 million while installing a new payroll system in 2006. The system, which was originally scheduled to go live in 2006, wasn’t operational until 2010 and ended up costing a total of $1.2 billion by the time it was completed.
That would be like ordering a $6 cup of coffee, only for it to take four times as long to make and cost $1,200 by the time it was done.
Which would make the coffee worth more than the laptop you’ll inevitably spill it on.
Multiple problems led to the gross overspend and under-execution of the payroll IT project, most of which included poor planning, research, and implementation by the network provider. It’s just one example of how improper planning can lead to disastrous financial consequences on top of a dysfunctional network.
It’s also a clear reminder of how important it is that you stay within your budget and deliver everything that was promised on time.
This network refresh guide was designed specifically to plan for any potential problems and as you plan your next project and help you:
Over the last 30-plus years, D-Link has worked with Networking and IT professionals on hundreds of thousands of networking projects all over the world. They’ve ranged from simple network refreshes and network upgrades to aggressive expansions and complete overhauls.
Throughout that time, there’s one thing we’ve noticed over the decades. With so much attention placed on the forefront of IT, we find that very little attention is given to one of the most common networking projects of all—the network refresh.
That’s why we put this ebook together. To help you perform your best when undertaking a network refresh. After all, given the pace at which the networking industry changes, even the most seasoned professional could use a little help.
Here’s what the guide will do for you.
This might not be the first time you’re refreshing your network. It probably won’t be the last, either. As you stare down the daunting challenge of refreshing your network, use this guide to create a plan for your current project—and your next. It goes beyond the basics of building your network, addressing the budget, performance, security, scalability, and efficiency needs of your network.
It can be hard to compete with large enterprises when you don’t have deep pockets to draw from. With this guide and some elbow grease, you can put together a budget-friendly network that keeps your business competitive now and down the road.
We’ll help you address potential issues such as integration, network capabilities, outdated software and products, planning, and training to make the process as smooth and complete as possible.
You may understand the importance of each piece of your network, but it’s not always easy getting buy-in from a supervisor and/or corporate decision makers. This guide can serve as a resource to help you justify the importance and cost of your proposal to your boss.

When you’re focused on piecing together the right network within a budget, it can be easy to forget all of the little things that go along with it, such as training staff and testing equipment. We’ll help you prepare an integration strategy that plans for all of the small details involved in a project like this.
No one can accurately predict the future of networking, but they can make strong assumptions based on previous trends and current information. Despite that, we do know one thing for certain—organizations that plan ahead and embrace upcoming trends see an average gross margin of 55% compared to the 37% growth of those that don’t.
The numbers are clear. It’s important to embrace a digital network transformation. We’ve highlighted the trends we see playing large roles in the upcoming world of business and their networks. By focusing on these aspects as you build your network, we believe you can strategically prepare your infrastructure for the evolution of business while maintaining everything you want and need for your network today.
By which, we mean the robot that will eventually become your manager.
This isn’t to say your organization should adopt an agile approach to everything, go all in on SDN (Software-Defined Networking), or move partially or entirely to the cloud. Organizations are unique and there are always some organizations that have no need for one or more of these solutions.
But what is truly important is to be aware of what’s going on so you can make the most informed decision possible for your network needs.
So let’s get started.
Damages from cybercrime are expected to cost businesses $6 trillion by the year 2021. It’s not just large enterprises either. Cities are being attacked, too. The town of New Haven recently coughed up $2,000 to “restore access to its computer system after a ransomware attack.” The attack came from outside the U.S.
One of the driving forces behind the increase in attacks and the costs associated with them are IoT devices. The more devices connected to your network, the more entry points there are for hackers.
Takeaway: Prepare your network for the growth of IoT and the potential cybercrime associated with it.
As previously mentioned, many industries are quickly adopting IoT devices in their everyday business operations. Retail, healthcare, and manufacturing are all using the data collected from devices to streamline their services and business operations.
Collecting, storing, managing, and analyzing that data presents both practical issues and security concerns. There’s also no governing body over the world of IoT devices at the present moment. The security standards and formats used—if used—are up to the manufacturers.
Takeaway: Prepare your network for the growth of IoT devices, fluctuating security standards, and all the data that will be collected, analyzed, and stored.
More enterprises are using analytics and machine learning to monitor, manage, predict, and prevent network failures. The number of large and medium-sized enterprises using machine learning will double in 2018 compared to 2017.
Takeaway: Ensure your network is capable of handling the bandwidth needed for the future of analytics and machine learning.
Most network operations are manually executed using the command line interface. This leads to human errors, which results in misconfigured network devices, security risks, and outages. Because of this, businesses are transitioning to automation services that will take complete this for them with fewer errors and time spent.
Suddenly, that robot manager joke seems a bit too real.
Takeaway: Consider how you will handle a shift towards automating if/when someone higher up requests it
With 802.11ax, or Wi-Fi 6, expected to take over as the primary wireless standard within the next few years, networks need to prepare for a rapid increase in bandwidth. One estimate projects a fourfold increase in the average amount of throughput each person will use.
The new Wi-Fi 6 is designed for high-density environments, such as public transportation, hotels, malls, stadiums, and other public venues. It will also be used to handle cloud solutions that include both on-location and virtual applications.
Takeaway: Anticipate heavy bandwidth needs within the next few years as content, customers, and businesses capitalize on new wireless capabilities.
With the rapid growth of IoT devices and sensors, more of the computing work will be performed on the edge of a network. Ultimately, this will cut down on the amount of data networks will need to handle, reducing latency and the overall cost to run a network.
Takeaway: Identify and anticipate your expected network needs based on newer edge computing devices.
While prem, cloud and hybrid IT strategies are the mainstays of networking, more and more network administrators are turning to Infrastructure as a Service (Iaas) for IT resources, such as compute, storage, and networking.
IaaS is highly scalable and makes it easier to mix and match different technologies and services from different vendors, allowing network administrators to choose the cloud services and networking products they want.
Takeaway: Evaluate your needs to determine the best possible architecture for your future network, comparing its costs and benefits relative to your current network
Unlike Virtual Machines (VMs), containers can all use the same OS and run multiple applications using the same hardware. In fact, it’s possible to run up to as many as eight containers on the same hardware that normally only handles one VM.
Because of how cost-efficient they are, more enterprises are implementing containers in their networks. In the past, containers have been used in virtual networks, but they’re starting to make their way toward the edge of computing space.
Takeaway: Ensure your network is prepared for the adoption of containers over virtual machines.
We designed this network refresh process to help you more easily capitalize on opportunities, find innovative solutions based on your budget, and ultimately make the best possible decisions for your network.
With that said, here are the four steps in this process.
Each step is broken down into subcategories to help you best prepare for your network refresh.

Sometimes we talk to professionals who simply want to swap out a few outdated switches for new ones, update some IP cameras, install some new access points, and call it a day. It’s essentially a patch. Others need to take approximately 10% to 40% of their oldest hardware and update it with the most appropriate replacements. Depending on the size of the organization, that could mean anywhere between 5 and 500 switches. It’s a big undertaking and a large part of why it’s so important to make the right decisions along the way.
No matter what, your network refresh should serve your current, short-term, and long-term needs. Think about what they will be over the next several years as you answer the following questions.
With those answers in mind, continue with the rest of Step 1.
Before you can identify the gaps in your network, you need to have a good idea of what you already have. Record the number of servers you operate and note the following for each:
Whether it was created in-house or purchased, make a list of all of your software. Include any software used for databases, CRMs, accounting, sales, marketing, and any other solutions you support.
It’s probably okay to leave Solitaire and Minesweeper out.
It’s important to have a high-level view of your network before you can dive into the finer details. Organize your equipment into categories based on similarities.
There’s no right way to group them, but you should focus on groups that help you plan your refresh. For example, you could place switches that are older than four-to-five years in one group, switches that specifically support IP cameras in another, and products with expired warranties in another.
If you find there’s overlap, use Venn diagrams to highlight equipment placed in multiple groups. You can also use this as a resource when presenting your proposal.
If you already have a diagram of your network and its infrastructure, use this step to update it if needed. It not, create a new one to use for this and future network refreshes.
Your existing network will become less efficient and more costly to maintain as it ages. To help plan your refresh, determine how much it currently costs to maintain it. You can guess if you need to, but try to use a number that’s as close as possible. Search through the trends over the last year to give yourself a better estimate if it helps.
Make sure to include the following costs:
Using the information you gathered during Step 1, you can now identify the potential solutions and vendors that can help you meet your business goals.
You already know what you need to upgrade and replace, but what are you missing? Identify the gaps in your network by assessing what you need to meet your goals. Use them to guide your search for vendors and solutions.
While you’re researching and/or contacting vendors, ask about what else they provide. Many vendors and resellers provide packaged deals that include extra services such as custom-designed solutions, installation, customer service, extended warranties, support, troubleshooting, and more.
Some of them even like to brag about their lifetime warranties and free customer support.
Use your infrastructure diagram, Venn diagram(s), future needs, and gaps to guide the conversations you have with vendors. Ask them about potential integration and compatibility issues you may have.
Focus on potential problems with:
Upgrading one server or switch may require increasing power or updating operating systems. Adding cameras may require more bandwidth or storage.
D-Link offers high-performance switches that often easily integrate into infrastructures with a mix of products you already have installed, and we’ll work with you to design custom solutions.
Where you host your applications (physical, virtual, or cloud server) affects the rest of your network, including the solutions you need, its performance, and its total cost. Ask your vendor about how potential solutions will affect all of these.
As you talk about your applications with vendors, determine which ones you’ll need to upgrade and whether or not that will affect the solutions you’ll need to host them. Start looking at applications that have expired warranties and move on from there. If you do need to upgrade, ask about the hardware you’ll need to support them.
Newer applications and software usually require more performance, and your older servers might not be able to provide the performance they need. That doesn’t mean you need to ditch them. It only means you need to determine what you need to support your software and business goals.
“Sorry, Steve, can you try reducing the file size to one kilobyte. My computer can’t handle it.”
This step is also good for further supporting your reasoning behind the solutions you’ve chosen and backs the importance of their performance, scalability, energy efficiency, and security.
Adding new tech means training people how to use it. Assess your team’s knowledge and skill level with each new application and solution you add. Use that information to ask your vendor about available training materials. Make sure to ask about who can provide training, how much it will cost, and the best time to schedule it.
Now that you know what you need, it’s time to plan your network refresh. This includes checking your numbers and scheduling the time needed. You’ll want to consider your site, applications, storage, infrastructure, business needs, staff, and other requirements throughout this process. A few things to plan for include:
Before you remove old hardware or upgrade to new hardware, consider the limitations and requirements of your physical site. Make note of the electrical outlets you have available and might need, plus any power and cooling requirements.
Pair your new and older applications with the hardware that can handle the requirements for each. Reassign old servers and switches for testing or development, if you want.
“Hey, Steve. It’s me again. Yeah, about the file you want me to print…”
Take a look at your network architecture requirements and jot down the following details, when applicable:
Consider your storage solution needs, including:
Compare your proposed network to your business requirements and determine whether or not it can support your needs now, next year, and three years down the road. Make sure to factor in your expected business growth.
Map out a timeline of everything that needs to be completed during your network refresh. Plan for each step, including the order, projected dates and durations, and how much everything will cost. As with the other steps, create contingency plans for unexpected problems and potential risks.
With everything else set, it’s time to refresh your network. This includes training your staff, notifying everyone affected by the changes, configuring the products, testing them, and deployment. Once you finish, it’s time to start planning your next upgrade.
Make sure you have a clear plan and process in place before starting, and make sure everyone understands their role and responsibilities. The clearer the instructions, the smoother the everything should go.
“Hey, Steve. I finished setting up the new 48-port switch. What’s next?”
When you buy packaged solutions, your server configuration is often completed for you. If not, your vendor or IT team should be able to take care of everything for you.
Before you make any changes, inform everyone who will be affected so they can prepare for any downtime.
Choose a few people or a large group for an initial test. You can make the testing period as long or short as you need to ensure everything is working properly.
Do not overlook this step! Make sure your network and infrastructure are prepared for any potential problems, including natural disasters. Set up backup and disaster recovery solutions and include a clear action plan to address each risk.
As you test everything, remain attentive to user comments and feedback. Use their comments to make adjustments as necessary. Again, the length of the testing period is up to you.
Schedule a time to provide the appropriate training for every member on your staff. Ensure they have a strong grasp of any new applications and products.
You’ve planned, implemented, installed, tested, and configured as much of your network as possible. It’s time to release it.
Keep the materials you created from this checklist someplace safe and organized for your next refresh. Use them to note any updates to your network and equipment, plus any licenses and warranties that either expired or you purchased/renewed. Update your networking maps, infrastructure, and any training materials as needed or when you have time. All of this will help simplify your next cycle refresh.
Now that you’ve made it through the guide, we’re here to help. As we said before, we’ve helped thousands of professionals like you build, refresh, upgrade, and expand their networks. That includes custom-designed solutions, too.
