33| ... | *[Top] Network Topologies:* TG-DUT1-DUT2-TG 3-node circular topology
34| ... | with single links between nodes.
35| ... | *[Enc] Packet Encapsulations:* Eth-IPv4 on TG-DUTn,
36| ... | Eth-IPv4-IPSec on DUT1-DUT2
37| ... | *[Cfg] DUT configuration:* DUT1 and DUT2 are configured with multiple\
38| ... | IPsec tunnels between them. DUTs get IPv4 traffic from TG, encrypt it\
39| ... | and send to another DUT, where packets are decrypted and sent back to TG
40| ... | *[Ver] TG verification:* TG finds and reports throughput NDR (Non Drop\
41| ... | Rate) with zero packet loss tolerance and throughput PDR (Partial Drop\
42| ... | Rate) with non-zero packet loss tolerance (LT) expressed in percentage\
43| ... | of packets transmitted. NDR and PDR are discovered for different\
44| ... | Ethernet L2 frame sizes using MLRsearch library.\
45| ... | Test packets are generated by TG on
46| ... | links to DUTs. TG traffic profile contains two L3 flow-groups
47| ... | (flow-group per direction, number of flows per flow-group equals to
48| ... | number of IPSec tunnels) with all packets
49| ... | containing Ethernet header, IPv4 header with IP protocol=61 and
50| ... | static payload. MAC addresses are matching MAC addresses of the TG
51| ... | node interfaces. Incrementing of IP.dst (IPv4 destination address) field
52| ... | is applied to both streams.
53| ... | *[Ref] Applicable standard specifications:* RFC4303 and RFC2544.
