5.1.1. 1n1l-10ge2p1x710-ethip4-ip4base-tg-ndrpdr suite¶
RFC2544: Pkt throughput for cross connected NICs with IPv4 traffic profile.
[Top] Network Topologies: TG-TG 1-node circular topology with single links between nodes.
[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, 254 flows per flow-group) with all packets containing Ethernet header, IPv4 header with static payload. MAC addresses are matching MAC addresses of the TG node interfaces.
[Ref] Applicable standard specifications: RFC2544.

TPUT on lightweight UDP transactions with L1 cross connect
[Top] Network Topologies: TG-TG 1-node circular topology with single links between nodes.
[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 client and server ASTF programs, generating packets containing Ethernet header, IPv4 header, TCP header and static payload. MAC addresses are matching MAC addresses of the TG node interfaces.
[Ref] Applicable standard specifications: RFC2544.
