| ... |
| ... | - **[Enc] Packet Encapsulations:** Eth-IPv4 for L3 IPv4 routing.
| ... |
| ... | - **[Cfg] DUT configuration:** DUT1 and DUT2 run the DPDK l3fwd \
| ... | application. DUT1 and DUT2 are tested with ${nic_name}.
| ... |
| ... | - **[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, 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.
