| ... | *[Enc] Packet Encapsulations:* Eth-IPv6 for IPv6 routing.
| ... | *[Cfg] DUT configuration:* DUT1 and DUT2 are configured with IPv6
| ... | routing and 2x1M static IPv6 /64 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, 1M flows per flow-group) with all packets
| ... | containing Ethernet header, IPv6 header withq IP and static payload.
| ... | MAC addresses are matching MAC addresses of the TG node interfaces.
| ... | Incrementing of IP.dst (IPv6 destination address) field is applied to
| ... | both streams.
| ... | *[Ref] Applicable standard specifications:* RFC2544.
