If you work for the federal government in IT then you know first hand that the complexity of Federal network and application deployments frequently include a diverse mix of many transport technologies.
Standard terrestrial connectivity is frequently linked via satellites to enable a global reach for solutions accessed by both civilian and military personnel. The high latency and the asynchronous characteristics inherent in these satellite links dictate particular attention when modeling test scenarios to determine application performance. It can be challenging to model these complex networks. Having worked with a number of our Fed Government customers over the years I’ve seen quite a lot of techniques used, some successfully, others with poor or inaccurate results.
The example shown below depicts a scenario in which the user is in a Humvee in motion. Three link conditions are defined and as test traffic is generated it is directed through the different links sequentially. 
These differentiated paths represent the change in the quality of service experienced when an end user’s position in relation to the uplink shifts. Satellite communication to the data center is also recreated here and in this case takes the form of asynchronous communication.
It is critical to be able to combine the diverse methods of transport and quality of service experienced in a single test. Can you do that now? If so, I’d love to know what method you are using. Are you using Shunra’s platform or another? What obstacles, if any, are you running into?
