| ... |
| ... | - **[Top] Network Topologies:** TG-DUT1-TG 2-node circular topology \
| ... | with single links between nodes.
| ... |
| ... | - **[Enc] Packet Encapsulations:** Eth-IPv4 for IPv4 routing. \
| ... | IEEE 802.1Q tagging is applied on link between DUT1-if2 and TG-if2.
| ... |
| ... | - **[Cfg] DUT configuration:** DUT1 is configured with IPv4 routing \
| ... | and two static IPv4 /30 route entries. DUT1 is 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 DUT1. TG traffic profile contains two L3 \
| ... | flow-groups (flow-group per direction, 254 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.
