A network controller, also known as a network control operator or a network control technician, is a tech specialist who monitors the overall engineering infrastructure of an organization. The individual plans, designs, and evaluates to ensure that network performance is not compromised. The main responsibility of a network control operator is to maintain the network by tracking the performance of the network as well as managing issues through routine troubleshooting. They restore to service any of the components comprising the DRSN or DISN networks, including multiplexers, data terminal equipment, data/voice communications equipment, and transmission media.

If the problems lie within a complex network, controllers resort to high-level troubleshooting. They work closely with an engineering team to provide network architecture design and recommend new technologies to improve existing performance.
