You’ve doubled your bandwidth but the network is still slow…what now?

You’ve doubled your bandwidth but the network is still slow…what now?

We all hate slow networks, we all get frustrated when our apps buffer and we all wish this modern day curse disappeared from our lives. Imagine how poor network managers are feeling with everyone pointing the finger at them! Even worse, think about your ISP- it’s their network so it must be their fault.

Enough of the frustration, we’ve all felt it and want it to go away. So what have end users tried or been sold as the solution? You guessed it, more bandwidth! Surely more bandwidth means better performance and a faster network. This, of course, comes at additional cost, often with a new longer term contract with your ISP and it also takes time to provision, so results you need could be weeks or months away.

Unfortunately, many network managers have tried this yet it hasn’t resulted in the slow network disappearing. To the contrary, users celebrate having more bandwidth by soaking it all up, and they often get a slower network and become even more frustrated at the ISP or telco that “sold them” more bandwidth. It’s doubly their fault!!

Why does this happen? Congestion! We’re all using more and more cloud based apps like O365, Skype for Business, hosted desktops etc. and they’re all hungry for bandwidth. Our laptops and smartphones want ever increasing bandwidth to run apps and updates, and of course let’s throw in all the video we’re consuming, whether it’s genuine business use or recreational. We all use the network when we need to, however when many users require bandwidth at the one time it doesn’t matter how big the link is, there is simply never enough bandwidth. In simple terms, your bandwidth and apps are analogous to freeways and cars. Too many users at one time and it’s gridlock!

What’s the answer? You need a traffic cop in your network with visibility of all the applications and how much bandwidth they’re consuming, as well as the ability to decide which applications get priority when congestion occurs.  

In a WAN environment, this is harder than it sounds. Firewalls provide some visibility of internet traffic and can shape internet traffic, but they don’t help with the WAN traffic. Products relying on NetFlow provide varying levels of WAN visibility but no traffic shaping and NetFlow has certain limitations, which adds yet more complexity (see 10 NetFlow limitations).

Sinefa provides real-time visibility of WAN and internet traffic and is able to identify in granular detail which apps and users are using all the bandwidth. A multi-tenanted cloud-based portal allows network managers to prioritize key business applications ensuring that when congestion occurs the important apps don’t slow down. Traffic shaping rules are super-flexible and can be applied across the WAN, links, AD Groups, AD users and even VLANs.

Set up a free, full-featured trial with Sinefa today. You most likely don’t need more bandwidth, and you might even be able to reduce the size of your data links Wouldn’t that be nice!
