The profiles and suites from the bench come with it Quoted with the plan FAQ ## Questions about the generator [All products](https://test4net.com/products?hsLang=en) [WANemu](https://test4net.com/products/wanemu?hsLang=en) [How CloudLAB works](https://test4net.com/cloudlab?hsLang=en) [Load and performance testing](https://test4net.com/services/load-performance-testing?hsLang=en) What hardware does it need? On CloudLAB, none on your side. For your own lab the requirements come with the demo report: server class, network cards and the rates each gives. Does it replace the commercial testers on the bench? No. It covers the common L4-7 and L2-3 cases at a lower price per gigabit; commercial units stay for protocol emulation and the cases where they are the reference. The report names the instrument behind every number. Can we bring our own traffic profile? Yes. Flow statistics or a capture from your network become a weighted profile; the data itself never leaves your side. The profile is saved with the report and reused on the next release. How are results validated? Every beta run goes next to a commercial unit on the same device. Counters that match the reference are marked as validated in the release notes; the rest is listed as a known gap. What does a beta seat cost? On CloudLAB it comes within the bench plan you book. A licence for your own lab is priced per gigabit after the beta. ## See the generator on your device A demo session on CloudLAB with a commercial unit next to it.
