Network Operation Center

A network operations center (NOC, pronounced like the word knock), 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 orsatellite 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.

NOCs analyze problems, perform troubleshooting, communicate with site technicians and other NOCs, and track problems through resolution. When necessary, NOCs escalate problems to the appropriate stakeholders. For severe conditions that are impossible to anticipate, such as a power failure or a cut optical fiber cable, NOCs have procedures in place to immediately contact technicians to remedy the problem.

Primary responsibilities of NOC personnel may include:

Network monitoring
Incident response
Communications management
Reporting

NOCs often escalate issues in a hierarchic manner, so if an issue is not resolved in a specific time frame, the next level is informed to speed up problem remediation. NOCs sometimes have multiple tiers of personnel, which define how experienced and/or skilled a NOC technician is. A newly hired NOC technician might be considered a “tier 1”, whereas a technician that has several years of experience may be considered “tier 3” or “tier 4”. As such, some problems are escalated within a NOC before a site technician or other network engineer is contacted.

NOC personnel may perform extra duties; a network with equipment in public areas (such as a mobile network Base Transceiver Station) may be required to have a telephone number attached to the equipment for emergencies; as the NOC may be the only continuously staffed part of the business, these calls will often be answered there.

A Network Operations Center rests at the heart of every telecom network or major data center, a place to keep an eye on everything.

Some of these NOCs are really “dressed to impress”, while others have taken a more mundane approach.

So, for inspiration, here is a set of pictures of different NOCs from telecom companies and data centers (and one content delivery network) that we here at Pingdom have collected from around the internet.

Dressed to impress

These NOCs are obviously designed to impress visitors on top of being useful. Also NOC constitutes the best Technical Experts of Networks as it acts as a heart for the network operations to run and to make human life more comfortable.

Slightly more discreet

While still impressive on a smaller scale, these NOCs have taken a slightly more conventional approach. We noticed a divide here. Data centers tend to have more scaled-back NOCs while telecom companies often fall in the “dressed to impress” category, perhaps partly due to having more infrastructure to monitor than the average data center (and shareholders).
