[Bhavesh Davda] Thanks for catching that. I was wondering why nobody respon= ded. I leave it up to you and the wider DPDK community to decide if this example= is useful. It was useful to us (VMware) and a couple of partner companies = in reproducing a packet drop on transmit issue at a telco/NFV operator lab = more easily than setting up the DPDK-based VNF from the vendor along with a= hardware load generator to generate the application-specific packet load. = It was much easier to just run this example application in a VM to reproduc= e the packet drop issue. What is different? I didn't find any other simple apps that only mimic Tx b= ursty behavior similar to this application. Maybe I missed some example app= lication that has such a capability. >=20 > Thanks > -- > Thomas
