Packet throughput Segment routing over IPv6 dataplane with one SID (SRH not inserted) test cases

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

• [Enc] Packet Encapsulations: Eth-IPv6-IPv6 on DUT1-DUT2, Eth-IPv6 on TG-DUTn for IPv6 routing over SRv6.

• [Cfg] DUT configuration: DUT1 and DUT2 are configured with IPv6 routing and static route, SR policy and steering policy for one direction and one SR behaviour (function) - End.DX6 - for other direction. DUT1 and DUT2 are tested with ${nic_name}.

• [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 (flow-group per direction, 253 flows per flow-group) with all packets containing Ethernet header,IPv6 header with static payload. MAC addresses are matching MAC addresses of the TG node interfaces.

Packet throughput Segment routing over IPv6 dataplane with Masquerading SRv6 proxy test cases

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

• [Enc] Packet Encapsulations: Eth-IPv6-SRH-IPv6 on DUT1-DUT2, DUTn-CNT and DUTn->TG, Eth-IPv6 on TG->DUTn for IPv6 routing over SRv6.

• [Cfg] DUT configuration: DUT1 and DUT2 are configured with IPv6 routing and static route, SR policy and steering policy for one direction and one SR behaviour (function) - End.AM - for other direction. DUT1 and DUT2 are tested with ${nic_name}.

• [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 (flow-group per direction, 253 flows per flow-group) with all packets containing Ethernet header,IPv6 header with static payload. MAC addresses are matching MAC addresses of the TG node interfaces.

• [Ref] Applicable standard specifications: SRv6 Network Programming - draft 3.and Segment Routing for Service Chaining - internet draft 01.
