+| Documentation | **RFC2544: Pkt throughput IPv4 WireGuard tunnel mode.**
+| ... |
+| ... | - **[Top] Network Topologies:** TG-DUT1-DUT2-TG 3-node circular \
+| ... | topology with single links between nodes.
+| ... |
+| ... | - **[Enc] Packet Encapsulations:** Eth-IPv4 on TG-DUTn, \
+| ... | Eth-IPv4-UDP-WireGuard on DUT1-DUT2.
+| ... |
+| ... | - **[Cfg] DUT configuration:** DUT1 and DUT2 are configured with \
+| ... | multiple WireGuard tunnels between them. DUTs get IPv4 traffic from TG, \
+| ... | and send to another DUT, where packets are decrypted and sent back \
+| ... | to TG.
+| ... |
+| ... | - **[Ver] TG verification:** TG finds and reports throughput NDR (Non \
+| ... | Drop Rate) with zero packet loss tolerance and 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 MLRsearch \
+| ... | library.
+| ... | Test packets are generated by TG on \
+| ... | links to DUTs. TG traffic profile contains two L3 flow-groups \
+| ... | (flow-group per direction, number of flows per flow-group equals to \
+| ... | number of WireGuard tunnels) 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. Incrementing of IP.src and IP.dst \
+| ... | are applied to both streams.
+| ... |
+| ... | - **[Ref] Applicable standard specifications:** RFC4303 and RFC2544.
