| Documentation | *RFC2544: Packet loss 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 throughput NDR (Non Drop Rate)\
| ... | with zero packet loss tolerance, then measures loss at this load\
| ... | while additional tunnels are configured.\
| ... | Test packets are generated by TG on
| ... | links to DUTs. TG traffic profile contains one 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 the stream.
| ... | *[Ref] Applicable standard specifications:* RFC4303 and RFC2544.
