| ... | *[Top] Network Topologies:* TG-DUT1-DUT2-TG 3-node circular topology
| ... | with single links between nodes.
| ... | *[Enc] Packet Encapsulations:* Eth-IPv4 on TG-DUTn,
| ... | Eth-IPv4-IPSec on DUT1-DUT2
| ... | *[Cfg] DUT configuration:* DUT1 and DUT2 are configured with multiple
| ... | IPsec tunnels between them. DUTs get IPv4 traffic from TG, encrypt it
| ... | and send to another DUT, where packets are decrypted and sent back to TG
| ... | *[Ver] TG verification:* In MaxReceivedRate test TG sends traffic
| ... | at line rate and reports total received/sent packets over trial period.
| ... | Test packets are generated by TG on
| ... | links to DUTs. TG traffic profile contains two L3 flow-groups
| ... | (flow-group per direction, 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 both streams.
| ... | *[Ref] Applicable standard specifications:* RFC4303 and RFC2544.
