Many operators around the world struggle with network congestion management. In some cases, network engineering teams have inherited several types of legacy network equipment resulting from acquisitions or asset purchases from other companies.
This equipment is expected to work together and integrate seamlessly, with no noticeable deviation to the end-subscriber’s experience or service level. Well, guess what – this is often far from the case – especially if you’re a network operator with small pockets of local service coverage across a very wide geographic area!
The problem is that blanket, network-wide improvements are extremely costly and represent an inefficient use of capital resources. Congestion will continue to occur, regardless of capacity expansion and advances in technology. Luckily, there are better ways to deal with these problems by targeting the areas of your network requiring most urgent attention.
Great – how does it work?
Business intelligence tools can assist by pinpointing critical bottlenecks that need to be fixed first. If all you have are basic reporting tools, spotting these bottlenecks will be challenging. With Sandvine’s (Network) Analytics tools, not only are you able to properly identify the areas of your network that require your immediate attention, you’re also able to alert everyone across the organization, from any cross-functional group of these problem areas and display detailed metrics such as video Quality of Experience (QoE) and Round-trip Time (RTT).
Network Analytics also allows for sophisticated analysis, providing insight into resource performance, displaying whether your peak period is increasing or decreasing, as well as in-depth projections of important subscriber quality metrics such as video Quality of Experience (QoE) and Round-trip Time (RTT).
Now I’m smarter – what’s next?
Network operators can also look towards implementing traffic optimization solutions that prioritize latency-sensitive applications. Knowing this will empower you to prioritize traffic of users that have NOT contributed disproportionately to congestion, ensuring that access to the Internet is fair for everyone and maximum QoE is maintained for most subscribers for the maximum amount of time.
Using detailed network analytics, in combination with traffic management solutions, operators can reap several benefits such as deferring capital investments, lowering infrastructure requirements and creating predictable expansion schedules.
If you are noticing that your subscriber churn rates are escalating, or your subscribers’ QoE is deteriorating, now could be time to invest in a decongestant. Business intelligence, coupled with traffic management strategy represents the difference between knowing exactly where to make improvements to your network, where to integrate or replace legacy resources – and not.
