| ...
| ... | - NDR and PDR tests
| ... | - 3-node topology, TG-DUT1-DUT2-TG, NAT44 is enabled between DUTs.
| ... | - Cores / threads: 1t1c, 2t2c, and 4t4c
| ... | - Framesize: 64B, 1518B, IMIX
| ... | - Packet: ETH / IP(src, dst) / UDP(src_port, dst_port) / payload
| ... | - scale: src: 1 user, 10 users, 100 users, ..., 4000 up to the memory
| ... | limit; 15 ports per user
| ...
| ... | *Low level description*
| ...
| ... | *[Top] Network Topologies:* TG-DUT1-DUT2-TG 3-node circular topology
| ... | with single links between nodes.
| ... | *[Enc] Packet Encapsulations:* Eth-IPv4-UDP for IPv4 routing.
| ... | *[Cfg] DUT configuration:* DUT1 and DUT2 are configured with IPv4
| ... | routing and two static IPv4 /24 and IPv4/20 route entries. DUT1 and DUT2
| ... | 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 either binary search or linear search
| ... | algorithms with configured starting rate and final step that determines
| ... | throughput measurement resolution. Test packets are generated by TG on
| ... | links to DUTs. TG traffic profile contains two L3 flow-groups
| ... | (flow-group per direction, one flow per flow-group) with all packets
| ... | containing Ethernet header, IPv4 header with UDP header and static
| ... | payload. MAC addresses are matching MAC addresses of the TG node
| ... | interfaces.
| ... | *[Ref] Applicable standard specifications:* RFC2544.
