Network support and data-driven fault isolation - Ericsson

soworos.blogspot.com

How to manage network complexity in the best way? This is a question frequently asked by service providers in their quest to simplify the operation of their virtualized networks. As part of reinventing operational models for greater efficiency and an improved networking experience, one focus area that has been identified is problem identification and fault isolation, where traditional product-level support is simply no longer sufficient.

The symptomatic effects of a disturbance can become apparent in many different layers of the entire network, and these are often impacted by the interworking of neighboring products, which calls for a vendor-agnostic approach. Effective network-level fault isolation is dependent on the interlocking of timely data capture and access to skills to address the root cause(s) of the problem.

Why data-driven fault isolation through Network Support? 

Service providers are seeking to apply new techniques to address network fault isolation, improving their ability to operate complex virtualized networks and navigate 5G ecosystems effectively. Isolating a network issue can be a very time-consuming, complicated process, and deep domain expertise is often required for effective data analysis to try to work out where the fault originated. Meanwhile, the networking experience is increasingly at risk.

Ericsson’s Network Support eases the burden of fault isolation on the service provider’s operations teams as we act in close collaboration, leveraging data-driven techniques and our vast global learnings. What starts with the uncovering of an S-KPI degradation, an intermittent site issue, or signs of increased dropped calls, could involve the analysis of a vast amount of data to isolate the underlying cause of the issue. And the cause is not always clearly identified through an alarm or alarm correlation.

Enabling informed decisions in real time is critical. In order for those on the front line to make fast, accurate decisions relating to the root causes of an issue, we leverage remote diagnostics and guided troubleshooting. That way, operations and field technicians can isolate faults faster and with increased accuracy during a single visit – or even before going to a site.

Isolating complex network issues in minutes or hours instead of days

At Ericsson, we have worked on addressing the network complexity and fault isolation challenges faced by the service provider. This work has resulted in the launch of our Network Support offering, which is designed to help. Our ability to take a knowledge-centric data-driven approach enables us to address end-to-end multi-domain networks effectively. We harness a unique set of support assets that help to isolate both hardware and software faults fast, and to resolve any issues promptly.

No longer does the service provider have to face the risk of prolonged incidents without the necessary network protection or support resources ready to act.

With Ericsson’s vast global knowledge base built to identify the plausible cause(s) of a problem, our Network Support has already facilitated:

• the reduction of fault isolation time by up to 50 percent
• the clear isolation of any hardware issue and identification of its root cause(s), helping to avoid up to 25 percent of site visits

Network Support is paving the way for addressing complex fault isolation for the service provider as we progress on our journey of 5G network evolution together.
