Job Description

Internetworking involves a collection of individual networks that are linked via devices and programs to create one large network. Commonly known network configurations include a high-speed data network known as a local area network (LAN) and a data communications network that covers a large area known as a wide area network (WAN). Internetworking technicians design and maintain such systems.


In addition to creating and designing networks and systems, internetworking technicians install and maintain programs for network routers, hubs, and switches. In many cases, they help troubleshoot problems for individuals and companies.

Internetworking technicians may also be known as computer systems and network technicians or networks systems and data communications analysts. According to O*Net Online, data communications and network systems analysts also:

  • Test software reliability
  • Determine future network needs
  • Design network configurations
  • Supervise network performance
  • Provide security measures


Educational requirements will vary by employer and job title. In most cases, internetworking technicians need an associate's or a bachelor's degree and potentially a certification.

Undergraduate degrees in computer network systems, computer information systems or a related subject are available at several universities and colleges. These programs offer core courses in topics such as networking and information system concepts, programming, operating systems and information system security. Some programs also offer certificates.

Certification programs are offered by technology companies such as Microsoft and Cisco. Cisco offers the Cisco Certified Internetworking Professional and the Cisco Certified Network Associate credentials, as well as other certification programs. Microsoft offers two primary certifications on internetworking: the Certified Systems Administrator and the Certified Systems Engineer credentials.

Salary Info and Job Outlook

According to the U.S. Bureau of Labor Statistics (BLS), the employment of network and computer systems administrators, including internetworking technicians, was expected to grow by 5% between 2018 and 2028. The BLS also reported the median annual salary earned by such administrators as $82,050 in May 2018.

Due to steady job growth, employment opportunities for network administrators, including internetworking technicians, should be good over the next decade. Holding a bachelor's degree and certification in the latest technology can help jobseekers catch the interest of employers.
