| ... |
| ... | - **[Top] Network Topologies:** TG-DUT1-DUT2-TG 3-node circular \
| ... | topology with single links between nodes.
| ... |
| ... | - **[Enc] Packet Encapsulations:** Eth-IPv4 for IPv4 routing.
| ... |
| ... | - **[Cfg] DUT configuration:** DUT1 and DUT2 are configured with IPv4. \
| ... | routing and 6x100k static IPv4 /32 route entries. 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 2 randomized L3 flow-groups (flow-group per direction, 100k \
| ... | 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.
