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