The dynamic behavior of the Internet has an enormous impact on the behavior of distributed applications, and problems like Packet Loss, Jitter and Latency can cause applications to fail. QualiTest’s Network Simulation Services allow you to foresee and avoid these problems.
The dynamic behavior of the Internet has an enormous impact on the behavior of distributed applications, such as ERP, storage, VoIP, video conferencing, ecommerce, datacenter consolidation, and web services. Problems like Packet Loss, Jitter and Latency can cause applications to fail.
Load testing has traditionally been focused on identification of software or hardware capacity problems, without taking into account the impact of the network on application performance. In many cases applications fail to perform to expected levels, despite load testing prior to roll-out.
Unfortunately, in many cases applications fail to perform to expected levels, despite load testing prior to roll-out. A load test environment that does not reflect all relevant real-world conditions cannot provide an accurate projection of how the application will perform once deployed. When this happens, the analysis and decisions leading up to approval to deploy the application may be misguided.
Increasingly, many pre-deployment testing labs have found that it is critical to incorporate the impact of WAN on application load testing. Integrating WAN emulation into load testing has been made easier to accomplish – more than ever before.
Shunra VE is Shunra’s flagship hardware and software network simulation product. It is a highly robust, comprehensive solution that creates a virtual network environment in your pre-deployment lab. It delivers a powerful, flexible and easy way to test the performance of your applications and network equipment under a wide variety of network impairments – exactly as if they were running in a real production environment – throughout the development lifecycle. Using Shunra VE you will understand the impact that the network and applications have on each other’s performance and on remote end-users’ experiences, and uncover and resolve production related problems – before rollout.
Designed for the needs of small- to medium-sized businesses, Shunra VE (SMB Edition) is a software product that simulates a point-to-point network link in your local lab or test bed. This enables you to test, compare and predict the performance of your applications over a WAN link under a wide variety of conditions – including latency, packet loss, jitter, and bandwidth constraints up to 10 Mbps.
Shunra VE Desktop Standard is a Windows-based client software solution that simulates a wide area network link so that you can test applications under a variety of current and potential network conditions – directly from your desktop.
An advanced version of the Shunra VE Desktop Standard, VE Desktop Professional is a Windows-based client/server network simulation software solution that enables test scenarios to be shared by users and managed from a central repository. Each Shunra VE Desktop client simulates a wide area network link so that you, and each member of your team, can test applications under a variety of current and potential network conditions – directly from your desktop.
