| ... | *[Top] Network Topologies:* TG-DUT1-DUT2-TG 3-node circular topology\
| ... | with single links between nodes.
| ... | *[Enc] Packet Encapsulations:* Eth-IPv4-UDP for IPv4 routing.
| ... | *[Cfg] DUT configuration:* DUT1 and DUT2 are configured with IPv4\
| ... | routing and one static IPv4 /24 route entries. Required ACL rules are\
| ... | applied to input paths of both DUT1 intefaces. DUT1 and DUT2 are tested\
| ... | with ${nic_name}.\
| ... | *[Ver] TG verification:* TG finds and reports throughput NDR (Non Drop\
| ... | Rate) with zero packet loss tolerance and 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, ${flows_per_dir}\
| ... | flows per flow-group) with all packets containing Ethernet header, IPv4\
| ... | header with IP protocol=61 and static payload. MAC addresses are\
| ... | matching MAC addresses of the TG node interfaces.
| ... | *[Ref] Applicable standard specifications:* RFC2544.
