NOC, also known as a "network management center", is one or more locations from which network monitoring and control, or network management, is exercised over a computer, telecommunication or satellite network.
NOCs are implemented by business organizations, public utilities, universities, and government agencies that oversee complex networking environments that require high availability.
NOC personnel are responsible for monitoring one or many networks for certain conditions that may require special attention to avoid degraded service.
Organizations may operate more than one NOC, either to manage different networks or to provide geographic redundancy in the event of one site becoming unavailable.
In addition to monitoring internal and external networks of related infrastructure, NOCs can monitor social networks to get a head-start on disruptive events.
