| ... | DUTs get IPv4 traffic from TG, encrypt it

| ... | *[Ver] TG verification:* TG finds and reports throughput NDR (Non Drop
| ... | Rate) with zero packet loss tolerance or throughput PDR (Partial Drop
| ... | Rate) with non-zero packet loss tolerance (LT) expressed in percentage
| ... | of packets transmitted. NDR and PDR are discovered for different
| ... | Ethernet L2 frame sizes using MLRsearch library.
| ... | Test packets are generated by TG on
| ... | links to DUTs. TG traffic profile contains two L3 flow-groups
| ... | (flow-group per direction, number of flows per flow-group equals to
| ... | number of IPSec tunnels) with all packets
| ... | containing Ethernet header, IPv4 header with IP protocol=61 and

| ... | node interfaces. Incrementing of IP.dst (IPv4 destination address) field
| ... | is applied to both streams.
