| Documentation | **RFC2544: Pkt throughput IPv4 IPsec tunnel mode.**
| ... |
| ... | - **[Top] Network Topologies:** TG-DUT1-TG 2-node circular topology \
| ... | with single links between nodes.
| ... |
| ... | - **[Enc] Packet Encapsulations:** Eth-IPv4 on TG-DUT1, \
| ... | Eth-IPv4-IPSec on DUT1-TG.
| ... |
| ... | - **[Cfg] DUT configuration:** DUT1 is configured with multiple IPsec \
| ... | tunnels between it and TG. DUT gets IPv4 traffic from TG, encrypts it \
| ... | and sends back to TG.
| ... |
| ... | - **[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 one L3 flow-groups (number of flows \
| ... | per flow-group equals to number of IPSec tunnels) with all packets \
| ... | containing Ethernet header, IPv4 header with IP protocol=61 and \
| ... | static payload. MAC addresses are matching MAC addresses of the TG \
| ... | node interfaces. Incrementing of IP.dst (IPv4 destination address) \
| ... | field is applied to the stream.
| ... |
| ... | - **[Ref] Applicable standard specifications:** RFC4303 and RFC2544.
