31| ... | VXLANoIPv4 with ${nf_chains} instances, ${nf_nodes} VMs per instance.*
32|
33| ... | *[Top] Network Topologies:* TG-DUT1-TG 2-node circular topology\
34| ... | with single links between nodes.
35| ... | *[Enc] Packet Encapsulations:* Dot1q-IPv4-UDP-VXLAN-Eth-IPv4 for L2\
36| ... | switching of IPv4. Dot1q-IPv4-UDP-VXLAN-Eth-IPv4 is applied on link\
37| ... | between DUT1 and TG.
38| ... | *[Cfg] DUT configuration:* DUT1 is configured with L2 bridge-\
39| ... | domain and MAC learning enabled. Qemu VNFs are connected\
40| ... | to VPP via vhost-user interfaces. Guest is running testpmd l2xc\
41| ... | interconnecting vhost-user interfaces, rxd/txd=1024. DUT1 is\
42| ... | tested with ${nic_name}.
43| ... | *[Ver] TG verification:* TG finds and reports throughput NDR (Non Drop\
44| ... | Rate) with zero packet loss tolerance and throughput PDR (Partial Drop\
45| ... | Rate) with non-zero packet loss tolerance (LT) expressed in percentage\
46| ... | of packets transmitted. NDR and PDR are discovered for different\
47| ... | Ethernet L2 frame sizes using MLRsearch library.\
48| ... | Test packets are generated by TG on links to DUTs. TG traffic profile\
49| ... | contains two L3 flow-groups (flow-group per direction, 256 flows per\
50| ... | flow-group) with all packets containing Ethernet header with .1Q, IPv4\
51| ... | header, UPD header, VXLAN header and static payload. MAC addresses are\
52| ... | matching MAC addresses of the TG node interfaces.
53| ... | *[Ref] Applicable standard specifications:* RFC2544, RFC7348.
