| ... | Contracts allowing full communications between the 2 external subnets.\

| ... | *[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\

| ... | (flow-group per direction, 254 flows per flow-group) with all packets\
| ... | containing Ethernet header including IEEE 802.1Q tagging, IPv4 header\
| ... | with IP protocol=61 and static payload. MAC addresses are matching MAC\
| ... | addresses of the TG node interfaces.
| ... | *[Ref] Applicable standard specifications:* RFC2544.
