| ... |
| ... | - **[Top] Network Topologies:** TG-DUT1-DUT2-TG 3-node circular \
| ... | topology with single links between nodes.
| ... |
| ... | - **[Enc] Packet Encapsulations:** Eth-IPv4-UDP for L2 switching of \
| ... | IPv4.
| ... |
| ... | - **[Cfg] DUT configuration:** DUT1 is configured with L2 bridge \
| ... | domain and MAC learning enabled. DUT2 is configured with L2 cross-\
| ... | connects. \
| ... | Required ACL rules are applied to input paths of both DUT1 intefaces. \
| ... | 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, ${flows_per_dir} flows per flow-group) with \
| ... | all packets containing Ethernet header, IPv4 header with UDP header \
| ... | and static payload. MAC addresses are matching MAC addresses of the TG \
| ... | node interfaces.
| ... |
| ... | - **[Ref] Applicable standard specifications:** RFC2544.
