IDG Contributor Network: 5 things analytics could tell you about your network in 2018

1. Whether your users are happy (without having to talk to them) It’s not always cool to admit, but the ultimate goal of every networker is to have happy users. Like many other thankless jobs, we only hear about problems. When we do, we react. But that isn’t ideal. What we really want is to know about problems as they are developing, before users complain. They don't even have to know.  But we do.A Network Management System (NMS) has been the traditional go-to solution to sniff out these sorts of problems. But most were designed for just one view of a certain part of the network using antiquated technology that doesn't provide any sort of predictive problem solving based on what the user is actually experiencing. It's like trying to figure out San Francisco traffic based on the status of the traffic signals. Just because the signals are working properly doesn’t mean the drivers (users) are having a good experience.To read this article in full, please click here

IDG Contributor Network: Network analytics will change everything

The way we manage and monitor networks is morphing. Passive, reactive tools are being replaced by more proactive network analytics systems that give the entire network team a single source of truth about network behavior and a much deeper understanding of where infrastructure issues are hiding and what to do about them.Before IT was forever changed by the arrival of mobile devices, virtualization and cloud apps, fixing network problems was relatively simple because users plugged into the network from one location to access local applications and resources.But with the proliferation of diverse wireless clients – a range of hardware using different versions of different operating systems (the permutations can quickly scale into the thousands) – and the use of applications and services that are often not under IT’s control, getting to the heart of individual user and systemic client network problems has become the new nightmare.To read this article in full, please click here

IDG Contributor Network: 5 reasons why IT can’t tame the user experience for the network manager

Every vendor today is spewing about the importance of managing the user experience. What this actually means, however, remains a mystery to most, and there are precious few approaches available to help you get a handle on the issue.Good and predictable user experience is no longer negotiable in this age of constant online business communications. Computer networks have effectively become the single most important tool driving corporate productivity.But user experience is one of the most difficult problems to address, especially on enterprise access networks, because each experience is influenced by a long list of moving parts, many of which are increasingly outside the control of IT. To read this article in full, please click here

IDG Contributor Network: Is Wi-Fi throughput testing useless?

Throughput testing has long been regarded as the best way to find great Wi-Fi products, validate WLAN design and troubleshoot user Wi-Fi issues.  It's not. Wi-Fi throughput testing generates a single data point under a specific scenario in a highly dynamic environment. That's it. In today's enterprise network environment, we need a lot more than that.+RELATED: What is MU-MIMO and can it boost Wi-Fi capacity?+It’s tempting, for example, to use Wi-Fi throughput tests to evaluate vendor equipment by determining the maximum TCP data rate (or speed) that, say, an access point can achieve with one or more client devices concurrently connected. But these tests don’t really reflect reality because you won’t see how that equipment really measures up until you have the network fully loaded and deployed.To read this article in full or to leave a comment, please click here
