Network Engineer Skills


Cisco is a networking company that produces routers and switches. Network engineers need Cisco skills to be able to configure and troubleshoot these devices.


Routing is the process of selecting paths in a network along which to send data. Routing is usually performed by network hardware devices such as routers, which use routing tables to make decisions about where to send data.

Routing is necessary because it allows data to be sent from one point to another without passing through every node in the network. This makes the network more efficient and reduces congestion.


Switching is a network engineering skill that allows you to connect different devices on a network so that they can communicate with each other. This is done by creating a switch configuration and then connecting the devices to the switch.


A firewall is a network security device that monitors incoming and outgoing traffic and allows or blocks certain types of traffic based on a set of security rules. Firewalls are used to protect networks from outside threats such as hackers, malware, and denial-of-service attacks.


A VPN, or Virtual Private Network, is a private network that extends across a public network, such as the internet. VPNs are used to allow users to securely connect to a private network from a remote location.

VPNs are commonly used by businesses to allow employees to securely connect to the company network from outside the office. They are also used by individuals to securely connect to sensitive information, such as banking details or personal health records.


A wireless network engineer is responsible for designing, implementing, and maintaining wireless networks. They need to have a strong understanding of radio frequencies and signal propagation in order to optimize the network. They also need to be able to troubleshoot problems and identify potential interference sources.


VoIP is a technology that allows you to make phone calls over the internet. You need it because it can save you money on your phone bill, and it can also be used to make international calls for free.


QoS (Quality of Service) is a network engineering technique used to manage and optimize network resources. It can be used to ensure that critical applications have the bandwidth and resources they need, while non-critical applications do not consume too much of the network's resources.


MPLS is a type of data-carrying technique used in high-performance computer networks. It is short for "Multi-Protocol Label Switching". MPLS directs data from one network node to the next based on short path labels rather than long network addresses, avoiding complex lookups in a routing table. The labels identify virtual links between distant nodes rather than endpoints.

MPLS is useful because it can improve network performance and reduce costs by simplifying the network infrastructure. It also allows service providers to offer new services and applications without having to make major changes to their existing networks.


BGP is a routing protocol used to exchange routing and reachability information between autonomous systems (AS) on the Internet.

BGP is the only exterior gateway protocol that scales to the size of the Internet. It is used to route traffic between different ASes on the Internet.

BGP is a complex protocol and requires a good understanding of networking to configure it correctly.


OSPF is a routing protocol that is used to find the best path between two devices on a network. It is used to route traffic between different networks and can be used to connect to different types of devices.


Network Address Translation (NAT) is a technique used to map one IP address to another. This is usually done to allow devices on a private network to communicate with devices on a public network. NAT can also be used to hide the true IP addresses of devices on a private network.

How to improve network engineer skills

As the world progresses, so does the need for reliable and efficient network engineers. With the increasing demand, it is important to continuously improve your skills as a network engineer. There are many ways to improve your skills, ranging from online courses to on-the-job experience. No matter your current skill level, there is always room for improvement.

One way to improve your skills as a network engineer is by taking online courses. There are many online courses available that can teach you the basics of networking, as well as more advanced concepts. These courses can be taken at your own pace and usually have a certificate of completion that can be added to your resume.

Another way to improve your skills is by getting experience on the job. Many employers are willing to train employees with little to no experience in networking. This hands-on experience can be invaluable and will help you learn the ropes of being a network engineer. You may also want to consider internships or apprenticeships at larger companies in order to get started in your career.

In addition to taking courses and gaining experience, there are other ways to improve your skills as a network engineer. Keeping up with new technologies and developments in the field is a great way to stay ahead of the curve. Reading industry publications and blogs, attending conferences and webinars, and networking with other professionals are all great ways to stay up-to-date on what’s new in networking.

No matter what your current skill level is, there are always ways to improve your skills as a network engineer. By taking advantage of online courses, gaining experience on the job, and staying up-to-date with new developments in the field, you can continuously improve your skills and become a top-notch network engineer.
