RFC2544: Pkt throughput GTPU test cases

  • [Top] Network Topologies: TG-DUT1-DUT2-TG 3-node circular opology with single links between nodes.

  • [Enc] Packet Encapsulations: Eth-IPv4-GTPU on DUT1-DUT2, Eth-IPv4 on TG-DUTn for IPv4 routing over GTPU tunnel.

  • [Cfg] DUT configuration: DUT1 and DUT2 are configured with IPv4.

outing and static routes. GTPU tunnel is configured on each DUT and enabled GTPU offload RX. DUT1 and DUT2 are tested with Intel-E810XXV.

  • [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 two L3 flow-groups 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.

  • [Ref] Applicable standard specifications: RFC2544.

RFC2544: Pkt throughput GTPU test cases

  • [Top] Network Topologies: TG-DUT1-DUT2-TG 3-node circular opology with single links between nodes.

  • [Enc] Packet Encapsulations: Eth-IPv4-GTPU on DUT1-DUT2, Eth-IPv4 on TG-DUTn for IPv4 routing over GTPU tunnel.

  • [Cfg] DUT configuration: DUT1 and DUT2 are configured with IPv4.

outing and static routes. GTPU tunnel is configured between DUT1 and DUT2. DUT1 and DUT2 are tested with Intel-E810XXV.

  • [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 two L3 flow-groups 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.

  • [Ref] Applicable standard specifications: RFC2544.
