5.2. ip6¶

5.2.1. 1n1l-10ge2p1x710-ethip6-ip6base-tg-ndrpdr suite¶

RFC2544: Pkt throughput for cross connected NICs with IPv6 traffic profile.

[Top] Network Topologies: TG-TG 1-node circular topology with single link between.
[Enc] Packet Encapsulations: Eth-IPv6 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, 1M flows per flow-group) with all packets containing Ethernet header, IPv6 header with static payload. MAC addresses are matching MAC addresses of the TG node interfaces.

[Ref] Applicable standard specifications: RFC2544.
