30| ... | *[Top] Network Topologies:* TG-DUT1-TG 2-node circular topology with\
31| ... | single links between nodes.
32| ... | *[Enc] Packet Encapsulations:* Eth-IPv4 for L2 bridge domain. IEEE\
33| ... | 802.1Q tagging is applied on link between DUT1-if2 and TG-if2.
34| ... | *[Cfg] DUT configuration:* DUT1 is configured with two L2 bridge\
35| ... | domains and MAC learning enabled. Container is connected to VPP via\
36| ... | Memif interface. Container is running same VPP version as running\
37| ... | on DUT. Container is limited via cgroup to use 3 cores allocated from\
38| ... | pool of isolated CPUs. There are no memory constraints. DUT1 is tested\
39| ... | with ${nic_name}.\
40| ... | *[Ver] TG verification:* TG finds and reports throughput NDR (Non Drop\
41| ... | Rate) with zero packet loss tolerance and throughput PDR (Partial Drop\
42| ... | Rate) with non-zero packet loss tolerance (LT) expressed in percentage\
43| ... | of packets transmitted. NDR and PDR are discovered for different\
44| ... | Ethernet L2 frame sizes using MLRsearch library.\
45| ... | Test packets are\
46| ... | generated by TG on links to DUT1. TG traffic profile contains two L3\
47| ... | flow-groups (flow-group per direction, 254 flows per flow-group) with\
48| ... | all packets containing Ethernet header, IPv4 header with IP\
49| ... | protocol=61 and static payload. MAC addresses are matching MAC\
50| ... | addresses of the TG node interfaces.
51| ... | *[Ref] Applicable standard specifications:* RFC2544.
