A network operations center (or NOC, pronounced like the word "knock") generally refers to one or more locations from which control is exercised over an infrastructure, transportation, computer, television broadcast, or telecommunications network.

Large organizations frequently operate more than one NOC, either to manage different networks or to provide geographic redundancy in the event of one site being unavailable or offline.

NOCs are responsible for monitoring alarms or certain conditions that may require special attention to avoid impact on the network's performance.

For example, in a telecommunications environment, NOCs are responsible for monitoring for power failures, communication line alarms (such as bit errors, framing errors, line coding errors, and circuits down) and other performance issues that may affect the network.

NOCs analyse problems, perform troubleshooting, communicate with site technicians and other NOCs, and track problems through resolution.
