Troubleshooting network application issues.

Hello,

We were constantly got reports about application latency between two locations which are geographically separated by 1000s of miles. Everytime our team used to check network link errors. But this approach was not finding any issues. We did research in using tools which can give more insight and fixed the problems. The tools used were,

• OPNET IT Guru from OPNET
• IXChariot from IXIA

OPNET IT Guru captures the data from end to end and combines the data to report possible causes. This tool got lot of different modules, which are expensive but they give lot of insight to application behaviour over the network. You can download OPNET IT Guru educational version from OPNET and model you network. This is pretty cool stuff.

IXChariot is used to generate certain type of traffic and capture the performance of the traffic between two end points. You can download trial version of IXChariot also.

There are various tools available in the market, but I recommend them because we used and found some good results.

Enjoy evaluating the software.
