| ... | *[Enc] Packet Encapsulations:* Eth-IPv4 for L2 switching of IPv4.
| ... | Eth-IPv4-VXLAN-Eth-IPv4 is applied on link between DUT1 and DUT2.
| ... | *[Cfg] DUT configuration:* DUT1 and DUT2 are configured with L2 bridge-
| ... | domain and MAC learning enabled. Qemu Guest is connected to VPP via
| ... | vhost-user interfaces. Guest is running DPDK testpmd interconnecting
| ... | vhost-user interfaces using 5 cores pinned to cpus 5-9 and 2048M
| ... | memory. Testpmd is using socket-mem=1024M (512x2M hugepages), 5 cores
| ... | (1 main core and 4 cores dedicated for io), forwarding mode is set to
| ... | io, rxd/txd=256, burst=64. DUT1, DUT2 are tested with 2p10GE NIC X520
| ... | Niantic by Intel.
| ... | *[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 either binary search or linear search
| ... | algorithms with configured starting rate and final step that determines
| ... | throughput measurement resolution. Test packets are generated by TG on
| ... | links to DUTs. TG traffic profile contains two L3 flow-groups
| ... | (flow-group per direction, 253 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, RFC7348.
