For some people, the term Network Operations Centre (NOC) might conjure up images of a control room from a seventies sci-fi film. Picture a room filled with giant screens, where people in beige shirts panic whenever a flashing light comes on.
That’s a far cry from the new generation of intelligent Network Operations Centres (iNOCs), which are no longer reactive centres where operators simply respond to alarms. iNOCs now help operators maintain network performance, anticipate infrastructure problems and inform investment strategy.
Network operators can now access more data than ever before. Making sense of that data can be a challenge, especially in a busy NOC. Throw in technological advances and changing customer habits and it’s easy to see why many teams are making the transition to a more data-driven, predictive model with increased automation.
A traditional NOC allows a technical team to identify potential threats and review the performance of your network. Specifically, it lets them:
That was once enough, but telecom operators now face new challenges, like storing and processing higher data volumes from increasingly diverse sources. That includes data from streaming sites, IoT services or over-the-top apps like WhatsApp and Facebook across a variety of connected devices.
In some cases, NOC teams are using data architectures that weren’t designed to handle such data volumes. Understanding a modern telecom ecosystem requires a different approach and next generation tooling.
An iNOC can see all nodes, network applications, services and technologies, giving it a 360 degree view of the network and services. This makes it an invaluable source of data for network health assessment and planning. Better insights ultimately lead to improved efficiency and performance, and happier customers.
Remember those flashing lights from the sci-fi film set? If those lights flashed a week before an issue arose, it would give the team more time to take action before a small problem becomes a big one.
Many traditional NOCs respond well to inbound incidents, but iNOCs focus on what could go wrong so you can develop a proactive approach to network issues. This allows you to anticipate threats to service performance and customer experience.
An iNOC helps you to address issues by giving you the tools to anticipate them. To understand service performance, you need to understand traffic flow. Changes in traffic flow characteristics can point to deep-seated problems within the network or issues with third parties.
Modern networks have multiple technology layers, all cooperating but operating independently. Traffic patterns are difficult to forecast and challenging to decipher, even when working with seemingly simple KPIs. For example, the relationship between dozens of underlying technical metrics influences congestion, jitter, delay and packet loss.
An iNOC needs to be able to dynamically interpret vast amounts of raw metrics from multi-technology environments and uncover useful insights. Doing so will enable it to not only uncover current problems, but also predict future issues by analysing underlying trends.
For instance, we developed a pattern identification feature that tracks common problems in a broadband network over time, calculating their frequency and location. Using pattern analysis and time series prediction, we built a model to determine when and where additional support would be required. This allowed our customers’ service assurance teams to fix issues before they occurred, ensuring a better customer experience.
An iNOC provides more detailed, granular views that allow technical teams to monitor and analyse system performance, preemptively tackling issues that could impact services. This helps to avoid service-level agreement breaches, which can result in costly penalties or reputational damage.
The evolution of data analytics and data science has resulted in new and inventive ways to identify warning signs or network issues. For example, we recently introduced new technology into our network service analytics solution, VisiMetrix. It can now forecast the impact of weather on quality of service (QOS) and anticipate radio access network (RAN) congestion. This award-winning technology allows mobile operators to accurately predict network issues up to seven days in advance.
We know that network congestion or disruption can test customer loyalties. Consistent speeds and connectivity topped households’ wishlists in a recent EY Digital Home survey. Almost a third of respondents said they would pay more for backup connectivity. Addressing connectivity problems at source will keep your network operating at an optimal level, which ultimately improves customer retention.
An effective iNOC should:
The move to an iNOC can be a catalyst for organisations to transform their operating model and embrace digital transformation. It lets you adopt a proactive, data-driven approach that can require a cultural shift as much as a technological one. It can therefore be a challenge, requiring people and technology to work in harmony, with a clear operational strategy in place to support the transformation.
Not only can VisiMetrix predict traffic congestion and inefficiencies within their network, but it combines network performance visualisation, monitoring and analytics on a single platform, enabling end-to-end service management. It can extract data from multi-vendor systems, predict trends, assess customer impact and facilitate early intervention.
Other communication service providers are also taking steps to evolve their NOC. Each organisation has unique challenges and specific goals. The key is to understand your customer’s behaviour and how they interact with your services.
Evolving toward an iNOC will help you to manage that information and decide what to do with it. Improved analytics, better predictive modelling, data-driven insights, better network traffic flow – the tools to give your organisation a competitive edge already exist.
It’s a significant departure from the reactive NOCs of the past. iNOCs help you make proactive decisions based on more reliable information. That can serve your organisation and your customers, both now and in the months or years ahead.
