1. The job outlook of a network professional
The outlook for new network professionals looks positive, as there is currently and will be a high demand for network professionals. According to a study from Burning Glass Technologies, there were 147,448 network professional job postings between 2019 and 2020. In addition (from the same source as 2021), there is a projected growth rate of 6.5% for demand in network engineers over the next ten years.
In addition, the US Bureau of Labor Statistics (BLS) also provides a similar forecast. According to BLS, network engineer employment is expected to grow 6% from 2016 to 2026 in the US.
A promising outlook
The number of network jobs in the field exceeds the number of prepared candidates.
So, if you are prepared and looking into the right places, you should land a good job opportunity.
But still, many companies and organizations are looking for highly qualified network professionals. They would often require (or desire) a handful of hard-to-attain certifications such as CCNP, AWS, VMware, plus a bachelor’s and sometimes a master’s degree and, on top of that, many years of experience in the field.
How to remain a qualified network professional
To remain a qualified network professional, you’ll need to be proficient with traditional network tools and practices. For example, you should know basics like:
- Understanding network fundamentals.
- Using packet analyzers like Wireshark or network mappers like Nmap.
- Connecting to remote (or local) devices with tools like SecureCRT and PuTTy.
- Monitoring a network with tools like PRTG monitor or SolarWinds
- Knowing basic configuration of routers or switches.
But to thrive in the field of computer networking, you’ll also need to know the cutting-edge. For example, building a scalable network architecture in the cloud with services like AWS VPC and Route53, a resilient and flexible WAN with SD-WAN, or knowing how to automate a network with configuration management tools like Red Hat Ansible.
In addition, although cybersecurity is already a field by itself, it is still firmly bound to computer networking. Therefore, as a network professional, you’ll need to keep your cybersecurity skills up to date.
2. Education in the Field of Computer Networking: Certifications vs. Career?
A University degree
The reality is that computer networking is more of a science than a vendor's specification or set of rules. Bear in mind that many of the certifications are vendor-made. They are created by the equipment/software manufacturers like Cisco, Microsoft, or VMware, which limits the scope to vendor-specific knowledge. For example, a lot of Cisco's certification focuses on their CLI or proprietary protocols.
An engineering degree will teach you the foundation of networking regardless of vendor. So, as a network engineer, you should be capable of using those fundamentals and building networks from scratch with whatever product a company is using.
According to Burning Glass, close to 85% of networking engineering jobs require a Bachelor’s degree, and a small percentage asks for a higher degree like a Master's or Ph.D.
When it comes to learning your networking ABCs, basic certifications like Cisco CCNA and CompTIA Network+ can be all you need. Before going into a more advanced computer networking career, taking a few certifications under your belt, and practicing in the field, can be a good start for your career. But as you accumulate some experience and knowledge, getting a university degree can take you to the next level. In addition, difficult certifications like CCIE, CISSP, or CCNP-Security, can even replace your need to get a computer networking degree.
As you advance in skills and hands-on experience, specialization can be the key to thrive in this competitive IT industry. Specialty certifications may range from cloud, security, virtualization, wireless, UC, etc.
These are the top 14 certifications that tend to pop up in the job listings:
- Cisco Certified Network Associate (CCNA)
- CompTIA Network+
- Wireshark Certified Network Analyst.
- Cisco Certified Network Professional (CCNP)
- Cisco Certified Internetwork Expert (CCIE)
- IT Infrastructure Library (ITIL) Certification
- SolarWinds Certified Professional (CDP)
- CWNP Certified Wireless Technician (CWT) certification
- CompTIA Security+
- Certified Ethical Hacker (CEH)
- Certified Information Systems Security Professional (CISSP)
- VMware Certified Professional – Network Virtualization
- Microsoft Certified Solutions Expert (MCSE)
- Microsoft Certified Solutions Associate (MCSA)
Although earning a degree in computer engineering can make you stand out from the crowded job market, certification is one of the only ways an employer can guarantee you fully understand a specific technology.
Practice with labs
To gain some experience, you can try free online projects and lab sources such as:
Get a router emulator, such as Cisco Packet Tracer or GNS3, in addition, Visio to create your diagrams, notepad++ to create your configurations, etc. The whole idea is that once you get the relevant skills, you can go and look for more advanced networking positions.
3. Working in the field
While CCNA and CCNP certifications might get you through an interview screening process, these won’t guarantee to get your feet on the door. An employer might want to bring you in for the added value you can provide, not precisely for your certifications and diplomas. For example, a seasoned network professional without a career and certifications may be more suitable for designing networks and putting out fires than a triple-certified professional.
Get your hands dirty and do the work
As you start with a career in computer networking and land your first job, you’ll likely start as a support level one. The key here is to gain experience, find your area of interest, and shape your skillset. And, if you are unable to land a job because of a lack of experience, you can volunteer, try internships programs, or help out in open-source projects.
A position and career will inevitably vary according to the industry and technology. For example, working as a Full Stack Engineer (FSE) can be good for finding your niche. But remember, specialization is what will set you apart from the rest. Areas of specialization may range from routing and switching, security, wireless, service providers, Unified Communications (Voice and Video networks), mobile networks, or data centers.
Roles in Computer Networking
The type of roles includes network support technicians and administrators that support and troubleshoot networks. On the other hand, network engineers take on more challenges and responsibilities, such as implementing and maintaining networks.
Other roles like network manager might include overseeing the entire network, personnel, and capacity planning. The last more advanced role is the network architect, which deals with design and testing in advanced and large-scale networks. The level of expertise in these roles can be sorted from entry-level to senior.
The typical tasks of a working network professional
- Maintain and monitor a computer network The primary responsibility of the computer network professional is to ensure that the communications across resources and users work. These resources may vary from workstations, servers, remote devices, printers, or any device with Internet (IoTs). A network professional must also ensure that access to these resources is reliable and fast and still works as the company grows. In addition, maintaining a network sometimes entails dealing with third-party providers such as Cloud, ISPs, CDNs, VPNs, mobile networks, etc. Also, as most servers and networking equipment runs on Linux, learning how to install, update, and configure Linux using CLI is vital for any network professional.
- Design a network A higher-level network engineer or architect can be responsible for designing a new or updating an existing network. Network designers must consider the physical attributes and layout of a building, plan for capacity, and adjust to the budget. This network design will also drastically change if wireless, voice or WAN considerations are involved.
- Project implementation and management This is the role when a network professional is appointed to oversee a networking project. A network manager may participate in anything, from designing, dealing with providers and personnel, managing hardware and software deployment, and doing testing procedures. Certifications like the PMP (although not easy) are optimal for such cases.
- Innovation and migrations The field of computing networking is constantly evolving and changing. Network professionals must find and integrate new technologies to protect and maintain the networks more efficiently. In addition, they should find the right balance between what's new and well-established. On the one hand, a next-generation network might be more efficient, faster, flexible, and cheaper, but probably less secure (more zero-day vulnerabilities). On the other hand, a well-established network might be convenient, easier to use, more secure, but probably a lot more expensive and rigid.
Other qualities that employers value highly (and sometimes even more than your technical skills) are your ability to communicate, how you work with others (teamwork), how you collaborate, and your critical thinking skills. A study in 2015 about soft skills found that over half of employers believe that skills like communication and teamwork were more important than academic results.
4. The typical salary range of network professional
“Work to become, not to acquire.” —Elbert Hubbard
There is a strong demand for network professionals, making the job offers better than in many other IT fields. A quick look into the computer networking job market might give you an idea of the average salary for a network professional.
The salary of a computer network professional is affected by various factors, including:
- Your education level The more prepared you are to undertake a computer networking job with certifications and degrees, the higher salary you can expect.
- Your experience level The pay is not the same for an entry-level “junior” networking support for an experienced “senior” networking engineer. However, as your responsibility within an organization’s network gets higher, your salary will be.
- Job location The salaries will vary according to the geographical location of your employer. The economy of a country plays a critical factor in the expected salary.
- Employer Salary will vary according to who is paying. Is the employer a startup, a well-established enterprise, are they in the public or private sector? These factors will inevitably affect the capabilities of an employer to compensate you.
