Machine learning takes a load off in network management


As networks become more software-driven, they generate vastly greater amounts of data, which provides some challenges: adhering to compliance and customer privacy guidelines, while harvesting the massive amounts of data—it is physically impossible for humans to tackle the sheer volume that is created. But the vast amounts of data also provide an opportunity for businesses: leveraging analytics and machine learning to gather insights that can help network management move from reactive to proactive to assurance. This doesn’t just mean a massive shift in technology because the human element won’t simply go away. Instead, by combining human intellect and creativity with the computing power AI offers, innovative design and management techniques will be developed to build self-improving intelligent algorithms. The algorithms allow networks to operate in a way that far outweighs networks of the past.

Reactive

In many organizations, network professionals have developed a semi-automated network management system using rule-based systems. When a rule, such as a certain load level that could slow network performance, is reached, it triggers an action, such as notifying network professionals of a potential service disruption. Although rules help network professionals react to events, they must be evaluated and updated frequently to ensure that they’re appropriate for, and in synch with, the ever-evolving network.

Proactive

Storing big data in data “lakes” is the first step in addressing large volumes of application, device, network service and user data generated by the networks. The next – very critical—step is deriving insights from the data. In one sense, this becomes easier because software networks are open and accessed by APIs, which provide the IT function with easier access to the data. Applying analytics to the data can, for example, help IT predict and address a lack of capacity in the network, as well as highlight issues so traffic can be re-routed, a bottleneck can be changed to increase capacity, or both. Ultimately, AI can help manage, maintain and protect the network, and analytics brings the insights that enable an organization to be proactive.

Assurance

Once an organization uses analytics on its network data, network professionals can apply AI and machine learning to drive additional, significant benefits. As the analytics captures insights—in the thousands—machine learning can start to develop patterns of understanding. Data flows in from the network, analytics draws insights against the data, and then machine learning processes those insights and creates new automated processes for handling similar events in the future. Rather than just monitoring for elevated levels of traffic, AI can help to track malicious activities such as attempted hacks. As the AI powering these algorithms becomes more intelligent, it will find faster and more foolproof methods of anticipating threats in the network, therefore helping network managers be better prepared.
