L2 Ethernet Looping =================== 10ge2p1x520-eth-l2xcbase-ndrdisc ```````````````````````````````` **RFC2544: Pkt throughput IPv4 routing test cases** - **[Top] Network Topologies:** TG-DUT1-DUT2-TG 3-node circular topology with single links between nodes. - **[Enc] Packet Encapsulations:** Eth-IPv4 for L2 frame forwarding. - **[Cfg] DUT configuration:** DUT1 and DUT2 run the DPDK testpmd application and use the io forwarding mode. DUT1 and DUT2 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.
