We looked at a number of products, but selected Maxwell because of the ability to create custom impairments and custom filters.  This is very useful in our testing environment.

Maxwell allowed us to emulate very slow links for an aviation test.  We emulated network traffic travelling from a ground location to air traffic control tower to a satellite and back again.

For your information: We have now gone through all [the Maxwell TCP/IP] fragmentation tests and our stack failed more then 50% of them. We have found 12 individual bugs in the stack so the Maxwell TCP/IP Test Suite  certainly does a good job :-).

Telit Wireless Solutions, www.telit.com, uses the Maxwell TCP/IP Test Environment to validate the performance of the IPEasy feature (embedded TCP/IP stack), reproducing critical TCP/IP scenarios coming from field trials and stressing GPRS and UMTS connections to GSM/GPRS/UMTS modems. Telit has integrated Maxwell Emulation into its test process connecting Maxwell to an Agilent 8960 test set. We have found the Maxwell TCP/IP tests a valuable addition to our test environment.

We use Maxwell to filter and emulate BACnet/IP traffic in order to pinpoint issues and problems at our customer's sites.   Using Maxwell has saved us hundreds of thousands of dollars in labor and equipment as we can faithfully emulate a customer site without re-creating the customer network.

As the world leader in IP video management, Verint's Software Test Group was in search of a network tool that would allow us to simulate the harsh, and some times unpredictable, impairment conditions of real world network scenarios with IP video solutions. We were very fortunate to discover the Mini Maxwell. The Mini Maxwell tool is a unique testing solution that is easy to operate and extraordinarily cost-effective. It enabled us to emulate real-time effects of various network conditions such as packet loss, latency, and bandwidth, helping us detect and work to resolve any problems we find well in advance during our development process, assuring optimal performance from the end-user perspective. The Mini-Maxwell is now an important, integral part of our test lab.
