|
| ... | *[Top] Network Topologies:* TG-DUT1-TG 2-node circular topology\
| ... | with single links between nodes.
| ... | *[Enc] Packet Encapsulations:* Eth-IPv4-TCP for IPv4 routing.
| ... | *[Cfg] DUT configuration:* DUT1 is configured with IPv4\
| ... | routing and two static IPv4 /24 route entries. DUT1 tested 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 DUTs. 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.
