31 | Documentation | **RFC2544: Packet throughput L2BD test cases with Dot1Q and
32 | ... | VXLANoIPv4 with ${nf_chains} instances, ${nf_nodes} VMs per instance.**
34 | ... | - **[Top] Network Topologies:** TG-DUT1-TG 2-node circular topology \
35 | ... | with single links between nodes.
37 | ... | - **[Enc] Packet Encapsulations:** Dot1q-IPv4-UDP-VXLAN-Eth-IPv4 for \
38 | ... | l2 cross-connect switching of IPv4 Dot1q-IPv4-UDP-VXLAN-Eth-IPv4 is \
39 | ... | applied on link between DUT1 and TG.
41 | ... | - **[Cfg] DUT configuration:** DUT1 is configured with L2 bridge- \
42 | ... | domain and MAC learning enabled. Qemu VNFs are connected \
43 | ... | to VPP via vhost-user interfaces. Guest is running testpmd l2xc \
44 | ... | interconnecting vhost-user interfaces, rxd/txd=1024. DUT1 is \
45 | ... | tested with ${nic_name}.
47 | ... | - **[Ver] TG verification:** TG finds and reports throughput NDR (Non \
48 | ... | Drop Rate) with zero packet loss tolerance and throughput PDR \
49 | ... | (Partial Drop Rate) with non-zero packet loss tolerance (LT) \
50 | ... | expressed in percentage of packets transmitted. NDR and PDR are \
51 | ... | discovered for different Ethernet L2 frame sizes using MLRsearch \
53 | ... | Test packets are generated by TG on links to DUTs. TG traffic profile \
54 | ... | contains two L3 flow-groups (flow-group per direction, 256 flows per \
55 | ... | flow-group) with all packets containing Ethernet header with .1Q, IPv4 \
56 | ... | header, UPD header, VXLAN header and static payload. MAC addresses are \
57 | ... | matching MAC addresses of the TG node interfaces.
59 | ... | - **[Ref] Applicable standard specifications:** RFC2544, RFC7348.
