| ... |
| ... | - **[Top] Network Topologies:** TG-DUT1-TG 2-node circular topology \
| ... | with single links between nodes.
| ... |
| ... | - **[Enc] Packet Encapsulations:** Eth-IPv4 for L2 switching of IPv4.
| ... |
| ... | - **[Cfg] DUT configuration:** DUT1 is configured with L2 bridge- \
| ... | domain and MAC learning enabled. Qemu VNFs are connected to VPP via \
| ... | vhost-user interfaces. Guest is running VPP IPv4 interconnecting \
| ... | vhost-user interfaces, rxd/txd=1024. 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 DUTs. 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 NFs nodes \
| ... | interfaces.
| ... |
| ... | - **[Ref] Applicable standard specifications:** RFC2544.
