7.10.1. 2n1l-10ge2p1x710-ethip4-loadbalancer-l3dsr-ndrpdr suite¶
RFC2544: Pkt throughput loadbalancer l3dsr test cases
[Top] Network Topologies: TG-DUT1-TG 2-node circular topology with single links between nodes.
[Enc] Packet Encapsulations: Eth-IPv4-UDP for LoadBalancer l3dsr.
[Cfg] DUT configuration: DUT1 is configured with LoadBalancer l3dsr and one static IPv4 /24 route entries. DUT1 tested with with ${nic_name}.
[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 DUT. TG traffic profile contains two L4 flow-groups (l3dsr use flow-group is only from TG to DUT, 6 flows for flow-group) with all packets containing Ethernet header, IPv4 header with IP protocol=17 and static payload. MAC addresses are matching MAC addresses of the TG node interfaces.
[Ref] Applicable standard specifications: RFC2544.
