But whether use any tools, we should Use unify interface, and the unify interface must use send packet tools supplied default interface, not develop a new interface. Eg, set line rate function, In our unify interface maye is set_line_rate, but set_line_rate will use ixia_set_line_rate or trex_set_line_rate, not develop a new ixia_set_line_rate or trex_line_rate. Now packet mode in framework we use scapy internal function for build packet and send packet, it is the root case why packet mode not stable. If we need use packet mode send packet for function, I think we can re-develop packet model. In new packet mode, we can use send_packet for send packet. But send_packet shoud call sendp function from scpay, when use scapy, use ixia_send_packet when use ixia.

Scapy command line will call the same function. Second, IXIA and Trex can do function test as they can transmit/sniff packets. There's one requirement that do function/performance cases in the same setup. At last, let's close this discussion for it can't help us figure out what's the root cause.

Scapy command line will call the same function. Second, IXIA and Trex can do function test as they can transmit/sniff packets. There's one requirement that do function/performance cases in the same setup. At last, let's close this discussion for it can't help us figure out what's the root cause.
