Hello,
 
Does anyone know or can recommend a PC network tool that...
- can setup arbitrary TCP and UDP (definable, scriptable) flows between PC probes on a network.
(like iperf, but from a centralized UI)
- can report packet loss, jitter, bandwidth, qos, mtu for these generated flows to the centralized application.
 
any comments welcome.
regards,
Lars
