31| ... | *[Top] Network Topologies:* TG-DUT1-TG 2-node circular topology\
32| ... | with single links between nodes.
33| ... | *[Enc] Packet Encapsulations:* Eth-IPv4 for L2 switching of IPv4.
34| ... | *[Cfg] DUT configuration:* DUT1 is configured with L2 bridge-\
35| ... | domain and MAC learning enabled. Qemu VNFs are connected to VPP via\
36| ... | vhost-user interfaces. Guest is running VPP IPv4 interconnecting \
37| ... | vhost-user interfaces, rxd/txd=1024. DUT1 is tested with ${nic_name}.
38| ... | *[Ver] TG verification:* TG finds and reports throughput NDR (Non Drop\
39| ... | Rate) with zero packet loss tolerance and throughput PDR (Partial Drop\
40| ... | Rate) with non-zero packet loss tolerance (LT) expressed in percentage\
41| ... | of packets transmitted. NDR and PDR are discovered for different\
42| ... | Ethernet L2 frame sizes using MLRsearch library.\
43| ... | Test packets are generated by TG on\
44| ... | links to DUTs. TG traffic profile contains two L3 flow-groups\
45| ... | (flow-group per direction, 254 flows per flow-group) with all packets\
46| ... | containing Ethernet header, IPv4 header with IP protocol=61 and static\
47| ... | payload. MAC addresses are matching MAC addresses of NFs nodes\
48| ... | interfaces.
49| ... | *[Ref] Applicable standard specifications:* RFC2544.
