34 | ... | - **[Top] Network Topologies:** TG-DUT1-DUT2-TG 3-node circular \
35 | ... | topology with single links between nodes.
37 | ... | - **[Enc] Packet Encapsulations:** Eth-IPv4 for L3 IPv4 routing.
39 | ... | - **[Cfg] DUT configuration:** DUT1 and DUT2 run the DPDK l3fwd \
40 | ... | application. DUT1 and DUT2 are tested with ${nic_name}.
42 | ... | - **[Ver] TG verification:** TG finds and reports throughput NDR (Non \
43 | ... | Drop Rate) with zero packet loss tolerance and throughput PDR \
44 | ... | (Partial Drop Rate) with non-zero packet loss tolerance (LT) \
45 | ... | expressed in percentage of packets transmitted. NDR and PDR are \
46 | ... | discovered for different Ethernet L2 frame sizes using MLRsearch \
48 | ... | Test packets are generated by TG on \
49 | ... | links to DUTs. TG traffic profile contains two L3 flow-groups \
50 | ... | (flow-group per direction, 253 flows per flow-group) with all packets \
51 | ... | containing Ethernet header, IPv4 header with IP protocol=61 and static \
52 | ... | payload. MAC addresses are matching MAC addresses of the TG node \
