RFC2544: Pkt throughput for cross connected NICs with IPv4 traffic profile.

  • [Top] Network Topologies: TG-TG 1-node circular topology with single link between.

  • [Enc] Packet Encapsulations: Eth-IPv4 for L1 cross connect patch.

  • [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 TG. TG traffic profile contains two L3 flow-groups (flow-group per direction, 500k 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:00:07:a1:1f, port01_dst fa:ce:00:00:00:00 - port01_dst fa:ce:00:07:a1:1f, port02_src fa:ce:00:00:00:00 - port02_src fa:ce:00:07:a1:1f, port02_dst ca:fe:00:00:00:00 - port02_dst ca:fe:00:07:a1:1f

  • [Ref] Applicable standard specifications: RFC2544.
