Proactive Wi-Fi Experience Monitoring


Let’s roll the clock back a few years, back to when wireless networking was seen as something handy to use in areas where you didn’t have any cable runs or was a temporary fix for an ad-hoc connection. Back to the days where a user was so ecstatic for their new found freedom of mobility that the odd drop of connection, or slightly slower page speed loading really wasn’t an issue. It was after all a luxury that they felt lucky to have…

Now, lets get back to the real world, back to 2018 and how do things compare.

More and more applications are being deployed for core services, what was once recreational traffic can now be seen as an enabler for business, studies have suggested that staff moral and productivity is increased by allowing recreational surfing, social media browsing and more. Wireless has become prolific, no longer a nice to have – many see it as the primary connection media and are adopting wireless first initiatives and businesses depend on it to run. No longer are your end users content with mediocre connectivity, the slightest glitch and ‘the Wi-Fi is down’ calls start flooding the helpdesk. Sorry to bring you back to earth with a bump.

Reactive or Proactive?

I’m not here to beat up any train of thought, there is a use case for both reactive tools and proactive tools and we can certainly help with both elements. For the purpose of this particular blog, I will focus on ways which we have successfully helped our clients to be proactive about understanding network & application performance from how the user (or client) sees it. Solutions that might give you a different opinion when your core monitoring tools tell you everything is O.K, just as a client would when they pick up the phone and raise a case telling you so.

In absolutely no particular order I will introduce 3 solutions to address this. Solutions which bring proactive monitoring of both Wifi experience and underlying network experience for both hosted and cloud applications.

Ixia Hawkeye

Ixia Hawkeye Test

Ixia Hawkeye enables you to conduct wireless network assessments by deploying wireless enabled endpoints in different distributed locations; or between different sites with software endpoints deployed on Android. iOS, Windows or Linux.

With the agents deployed, you can now conduct network assessments and run real world traffic over your Wi-Fi (and supporting core) network, emulating typical applications and measure end user experience. Hawkeye measures experience metrics like voice MoS score, or application response time over time and per location. It can be permanently deployed or deployed on an ad-hoc method due to the flexible nature of the way it is licensed.

“By running Hawkeye continuous Wi-Fi assessments on my campus, I am able to monitor the quality of access to critical services like Lync and SAP from different buildings and floors and be very reactive when I detect degradation, quickly identifying where to diagnose and solve issues”

There are 2 type of test, the Node to Node, or the Real Service Test.

In Node to Node, one endpoint generates application traffic and sends to another endpoint over the live network. The receiving node is in turn able to relay the information and statistics back to the management interface.

In Real Service Tests, endpoints generate application traffic and send to network devices such as servers and sends its metrics back to the management interface.

application library

Ixia have a long standing history in the network test market and it would come as no surprise that they have the largest application test library in the industry. This enables you to create real world synthetic tests specific to your needs.

With the application library, you are able to:

Ensure Quality of Experience (QoE) of end users using service such as Voice, Skype for Business or video conferencing.

Ensure that users can access business critical cloud applications such as Office365, YouTube, Dropbox and more.

Qualify and maintain network SLAs with diagnostic tools for IP Transport testing – Assess layer 3 network performance indicators (loss, jitter, delay)

Validate core services such as DNS and traceroute.

Qualify and quantify the real capacity of your network circuits Test TCP and UDP at speeds up to line rate.


NETSCOUT enGenius Pulse

engenius pulse service dashboard

NETSCOUT’s enGenius Pulse is architected in a similar way to that of Ixia, where as you have a centralised monitoring service dashboard and distributed endpoints. The endpoints come either as a dedicated small footprint PoE powered micro appliance or one that can be added as a lightweight piece of software on a laptop or PC for example.

engenius pulse hardware endpoint

Once the endpoint is deployed you can immediately begin testing proactively. The devices will behave like a client, obtaining IP addresses, DNS and then communicating the services under test be it core back in the datacenter, or cloud applications, or even VoIP between sites; the micro appliances will call each other and report back the status of the calls – which is a really nice feature.

NETSCOUT Pulse transaction dashboard

NETSCOUT’s enGenius Pulse will enable you to track actions through an application, so for example when you have to traverse log-in screens for applications such as SalesForce, or Office365 helping you to understand the tru application and not just its front page load.

Integration with NETSCOUT enGeniusONE

It goes without saying that there is a very slick integration with the NETSCOUT enGeniusONE service assurance platform, meaning that when you combine Pulse with enGenuisONE you have a full core-to-edge solution giving a enterprise wide visibility of your critical infrastructure and application performance.

Distributed Wi-Fi End User Experience monitoring

Aruba User Experience Insight (Cape)

Another fantastic way to look at end user performance over the wireless network is by using HPE Aruba Service Assurance which was formerly known as Cape. So how is this different?

Cape sensors look similar to a small wireless access point and are deployed where your end users would be, and from where you really want to monitor your end user experience. The only other component is a cloud subscription, to where the sensors communicate and report all of their findings.

Aruba Cape dashboard overview

In answer to ‘how is this different?’ a good place to start is right at the dashboard. Cape’s dashboard utilises a very easy to read traffic light system of service availability and takes a detailed understanding of service availability to a different audience, with as much technicality as you would need for a 2/3rd line tech.

In the dashboard you configure what you want to test, cloud services and business apps, remote servers back in the datacentres and the test profiles are executed from the sensors with full detailed analysis being sent back to the dash for analysis and long term trending.

The Cape sensors connect in to the network just like a client would, and communicate with the selected applications, report back all transaction statistics over time whilst recording all of the wireless statistics to correlate at the same time. 

7Signal Distributed Wireless Network Monitoring

7Signal is an overlay distributed monitoring platform that employs sensors within your environment that are used to connect in to your network and run a number of synthetic transactions to test the performance of real world applications, whilst recording both active and passive statistics.

Wi-Fi KPI & SLA Measurement/Monitoring

Something extra that we really like here, is the way that 7Signal have a really unique way of getting to the specifics that matter – in the way that they measure and report against pre-determined SLA/KPI targets so that you are kept abreast of how close (or far) you are from meeting your objectives.
