What is a network engineer?

Network engineers are responsible for designing, installing, maintaining, troubleshooting, and repairing computer networks. They design and install hardware and software components, including routers, switches, servers, firewalls, and wireless access points.

They also maintain existing systems and fix problems when they arise. Network engineers work closely with IT managers to ensure that computers and networking equipment operate efficiently and securely.


  • Designing and implementing network solutions
  • Installing, configuring, and testing new or upgraded network devices
  • Maintaining the security of your organization’s network
  • Troubleshooting network issues
  • Performing routine maintenance on network devices

What does a network engineer do?

Network engineers deliver high-availability network infrastructure for users to access their online and on-site IT activities. Network engineers often overlap roles, such as computer networking architect or security system engineer, and work internally within organizations or as outside consultants

Network engineers design and install networks, troubleshoot performance problems, monitor network traffic, and configure security systems such as firewalls. They often report to their CIO, CISO, and other line-of-business leaders to discuss and decide on overall business goals, policies, and network status updates. Network engineers often work closely with project managers, other engineers, and technical staff to manage capacity and perform remote or on-site troubleshooting.

Network engineer certifications and training?

Network engineering training courses are offered by a number of universities and educational institutions. Institutions offer certifications that can boost professional credentials.

Many engineers believe that additional qualifications and training are tightly linked to the Cisco engineering certification programs, which offer several levels of career training for engineers. There are other certifications available from vendors and organizations like Juniper Networks, Microsoft (Windows Server), Aruba, Alcatel Lucent Enterprise, Riverbed Technologies, SolarWinds, Hewlett Packard Enterprise, Extreme Networks, and the Internet Protocol version 6 (IPv6) Forum.

Some of the more popular network engineer certifications include:

  • CompTIA Network+
  • Cisco Certified Technician (CCT) Routing & Switching
  • Cisco Certified Network Associate (CCNA)
  • Cisco Certified Network Professional (CCNP)
  • Cisco Certified Internetwork Expert (CCIE)
  • VMware Certified Professional — Network Virtualization (VCP-NV).

What Skills Do Network Engineers Need?

Network engineers use a wide variety of cross-functional skills, including software development, network design, and security, and They interact with people and use technology. It’s a highly technical field but requires strong communication, problem-solving, and analytical skills the stereotype of the loner network engineer who spends most of his or her day alone at a computer in a cubicle or server closet is outdated’. Networking professionals at larger companies work closely with executives, vendors, and colleagues across departments. At large companies, there are usually teams of people who handle different aspects of the business. These teams may include IT help desk employees (who answer customer questions), administrators (who manage the company’s computers), network operations staff (who maintain the company’s)

Network engineers are increasingly needed by companies who want to hire them. Network engineers need skills in standard network protocols; TCP / IP, DNS, DHCP, switching and routing; firewalls and network security; VPNs and wireless networking. As companies increasingly look for network engineers with programming skills, suggesting that networking is moving toward an approach that embraces automation and/or Network as Code. Infrastructure as Code.

As networking evolves, so too will the skills networking engineers need to stand out. These

  • Ansible and Puppet
  • API
  • Cloud architecture
  • NetDevOps
  • Network automation
  • Programming
  • Software-defined networking
  • Virtualization

What Network Engineers Do Is Evolving?

Networking professionals still need knowledge of routers, switches, firewalls, etc… But now they need to be skilled in automating, virtualizing, and using the cloud. They should also be familiar with security and cyber-attacks. Networking experts should take advantage of higher education opportunities to stay ahead of technology. An online Master’s degree program from SMU Lyle is designed to help students develop the skills needed to advance in the industry. Students learn about various technologies and how they work together to create networks.

The coursework includes a combination of lectures, tutorials, case studies, and practical exercises. The curriculum also covers topics such as network design, wireless networking, IP addressing, routing protocols, firewall configuration, VPNs, and more. Students are taught by faculty members who have worked for major companies like Cisco Systems, Juniper Networks, and Microsoft Corporation. https Spotify com Pair Activation

The program can be completed entirely online or on-campus at the School of Engineering at Southern Methodist University (SMU). It consists of three phases: core courses, electives, and an internship. Core courses include Introduction to Computer Science, Introduction to Programming, Operating System Concepts, Algorithms I, Algorithms II, Data Structures, Database Management, and Advanced Topics in Software Design. Elective classes cover areas such as Web Development, Artificial Intelligence, Cyber Security, and Cloud Computing. During the internship phase, students complete an internship that will give them real-world experience working with network devices and software.
