TRIPPing On Lync

Saturday, November 10th, 2012

Microsoft Lync can require as much or as little bandwidth as you can give it, according to what you are using Lync for. At its most basic, Lync is a tool for instant messaging. At its most complicated, Lync can plug-in to Microsoft Outlook, schedule a video conference with 10 of your coworkers (without posting the fact that you had said video conference to your Google+ timeline btw), share your screen so you can step your parents through setting up Windows RDP to fix a problem on their computer and pass PBX style traffic to provide voice services; all the while still letting you instant message your wife that you’ll be late coming home because you are stuck on the video conference, a screen share and a phone call also being managed with Lync.

Because you can do so much with Lync, as you start to do some of the more bandwidth intensive tasks, you might notice performance issues. Especially if you have an office of people running Office 365 and Lync Online to communicate with customers and one another. There are two types of performance to be concerned with with regards to any video or VoIP-based teleconference solution. The first is latency and the second is speed. TRIPP stands for the Transport Reliability IP Probe. TRIPP can be used to test your connection and return with information about what kind of performance you can expect to have.

TRIPP is easy to use. Open a browser to http://trippdb3.online.lync.com and click on Start Test.

When prompted, provide a Session ID (if you don’t have one, simply enter 0 and hit the Return key).

The test then runs. The first step is to look at latency. Wait for the rest to complete.

When finished, you’ll see a summary page that outlines the kind of performance you can expect from Lync.

If you have latency issues then it’s often due to too many hops for various sessions. This can be difficult to troubleshoot as it’s often up to an ISP to resolve routing table issues or provide better services. Bandwidth problems can be addressed by reducing the number of services on your network or increasing your throughput. You can also associate a higher priority for this type of traffic. Consistency of Service often comes down to QoS.

So far, I’ve managed to run TRIPP on Windows, Linux and as you can see from these screens, OS X.
