| Documentation | *RFC2544: Packet throughput L2BD test cases with vhost*
| ...
| ... | *[Top] Network Topologies:* TG-DUT1-DUT2-TG 3-node circular topology
| ... | with single links between nodes.
| ... | *[Enc] Packet Encapsulations:* Eth-IPv4 for L2 switching of IPv4. 802.1q
| ... | tagging is applied on link between DUT1 and DUT2.
| ... | *[Cfg] DUT configuration:* DUT1 and DUT2 are configured with L2 bridge-
| ... | domain and MAC learning enabled. Qemu Guest is connected to VPP via
| ... | vhost-user interfaces. Guest is running DPDK testpmd interconnecting
| ... | vhost-user interfaces using 5 cores pinned to cpus 5-9 and 2048M
| ... | memory. Testpmd is using socket-mem=1024M (512x2M hugepages), 5 cores
| ... | (1 main core and 4 cores dedicated for io), forwarding mode is set to
| ... | io, rxd/txd=1024, burst=64. Scheduler policy is set to SCHED_RR with
| ... | priority 1 for all Qemu CPUs. DUT1, DUT2 are tested with 2p10GE NIC X520
| ... | Niantic by Intel..
| ... | *[Ver] TG verification:* TG finds and reports throughput NDR (Non Drop
| ... | Rate) with zero packet loss tolerance or 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, 5k flows per flow-group) with all packets
| ... | containing Ethernet header, IPv4 header with IP protocol=61 and static
| ... | payload. MAC addresses ranges are incremented as follows:
| ... | port01_src ca:fe:00:00:00:00 - port01_src ca:fe:00:00:13:87,\
| ... | port01_dst fa:ce:00:00:00:00 - port01_dst fa:ce:00:00:13:87,\
