+| ...
+| ... | *[Top] Network Topologies:* TG-DUT1-DUT2-TG 3-node circular topology
+| ... | with single links between nodes.
+| ... | *[Enc] Packet Encapsulations:* Eth-IPv4 for L2 cross connect. 802.1q
+| ... | tagging is applied on link between DUT1 and DUT2.
+| ... | *[Cfg] DUT configuration:* DUT1 and DUT2 are configured with L2 cross-
+| ... | connect. 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.
