| Documentation | **RFC2544: Pkt throughput L2XC test cases with vhost and vpp \
| ... | link bonding**
| ... |
| ... | - **[Top] Network Topologies:** TG-DUT1=DUT2-TG 3-node circular \
| ... | topology with single links between TG and DUT nodes and double link \
| ... | between DUT nodes.
| ... |
| ... | - **[Enc] Packet Encapsulations:** Eth-IPv4 for L2 cross connect. \
| ... | 802.1q tagging is applied on link between DUT1 and DUT2.
| ... |
| ... | - **[Cfg] DUT configuration:** DUT1 and DUT2 are configured with VPP \
| ... | link bonding (mode LACP, transmit policy l34) on link between DUT1 and \
| ... | DUT2 and L2 cross- connect. Qemu VNFs are \
| ... | connected to VPP via vhost-user interfaces. Guest is running VPP l2xc \
| ... | interconnecting vhost-user interfaces, rxd/txd=1024. DUT1/DUT2 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 the TG node interfaces.
| ... |
| ... | - **[Ref] Applicable standard specifications:** RFC2544.
