Voleatech uses two different test tools:
a. IPerf3 for a simple test with TCP
b. TRex Traffic Generator for IMIX tests. Here we use an STL profile that sends several packets per port and simulates several thousand clients.
IMIX traffic consists of UDP traffic 7x 64 byte packets, 4x 594 byte packets, 1x 1514 byte packets (without Ethernet FCS)

Is Open Source Better Than Closed Source?2020-08-25T11:33:58+02:00

An open source firewall has the advantage that the source code can be viewed and that many
Developers write the code. Backdoors are not possible and errors are found and repaired quickly. So you don’t have a black box and thus more control and security.
