-VPP Forwarding Modes
---------------------
-
-VPP is tested in a number of L2, IPv4 and IPv6 packet lookup and
-forwarding modes. Within each mode baseline and scale tests are
-executed, the latter with varying number of FIB entries.
-
-L2 Ethernet Switching
-~~~~~~~~~~~~~~~~~~~~~
-
-VPP is tested in three L2 forwarding modes:
-
-- *l2patch*: L2 patch, the fastest point-to-point L2 path that loops
- packets between two interfaces without any Ethernet frame checks or
- lookups.
-- *l2xc*: L2 cross-connect, point-to-point L2 path with all Ethernet
- frame checks, but no MAC learning and no MAC lookup.
-- *l2bd*: L2 bridge-domain, multipoint-to-multipoint L2 path with all
- Ethernet frame checks, with MAC learning (unless static MACs are used)
- and MAC lookup.
-
-l2bd tests are executed in baseline and scale configurations:
-
-- *l2bdbase*: Two MAC FIB entries are learned by VPP to enable packet
- switching between two interfaces in two directions. VPP L2 switching
- is tested with 254 IPv4 unique flows per direction, varying IPv4
- source address per flow in order to invoke RSS based packet
- distribution across VPP workers. The same source and destination MAC
- address is used for all flows per direction. IPv4 source address is
- incremented for every packet.
-
-- *l2bdscale*: A high number of MAC FIB entries are learned by VPP to
- enable packet switching between two interfaces in two directions.
- Tested MAC FIB sizes include: i) 10k with 5k unique flows per
- direction, ii) 100k with 2 x 50k flows and iii) 1M with 2 x 500k
- flows. Unique flows are created by using distinct source and
- destination MAC addresses that are changed for every packet using
- incremental ordering, making VPP learn (or refresh) distinct src MAC
- entries and look up distinct dst MAC entries for every packet. For
- details, see :ref:`packet_flow_ordering`.
-
-Ethernet wire encapsulations tested include: untagged, dot1q, dot1ad.
-
-IPv4 Routing
-~~~~~~~~~~~~
-
-IPv4 routing tests are executed in baseline and scale configurations:
-
-- *ip4base*: Two /32 IPv4 FIB entries are configured in VPP to enable
- packet routing between two interfaces in two directions. VPP routing
- is tested with 253 IPv4 unique flows per direction, varying IPv4
- source address per flow in order to invoke RSS based packet
- distribution across VPP workers. IPv4 source address is incremented
- for every packet.
-
-- *ip4scale*: A high number of /32 IPv4 FIB entries are configured in
- VPP. Tested IPv4 FIB sizes include: i) 20k with 10k unique flows per
- direction, ii) 200k with 2 * 100k flows and iii) 2M with 2 * 1M
- flows. Unique flows are created by using distinct IPv4 destination
- addresses that are changed for every packet, using incremental or
- random ordering. For details, see :ref:`packet_flow_ordering`.
-
-IPv6 Routing
-~~~~~~~~~~~~
-
-Similarly to IPv4, IPv6 routing tests are executed in baseline and scale
-configurations:
-
-- *ip6base*: Two /128 IPv4 FIB entries are configured in VPP to enable
- packet routing between two interfaces in two directions. VPP routing
- is tested with 253 IPv6 unique flows per direction, varying IPv6
- source address per flow in order to invoke RSS based packet
- distribution across VPP workers. IPv6 source address is incremented
- for every packet.
-
-- *ip4scale*: A high number of /128 IPv6 FIB entries are configured in
- VPP. Tested IPv6 FIB sizes include: i) 20k with 10k unique flows per
- direction, ii) 200k with 2 * 100k flows and iii) 2M with 2 * 1M
- flows. Unique flows are created by using distinct IPv6 destination
- addresses that are changed for every packet, using incremental or
- random ordering. For details, see :ref:`packet_flow_ordering`.
-
-SRv6 Routing
-~~~~~~~~~~~~
-
-SRv6 routing tests are executed in a number of baseline configurations,
-in each case SR policy and steering policy are configured for one
-direction and one (or two) SR behaviours (functions) in the other
-directions:
-
-- *srv6enc1sid*: One SID (no SRH present), one SR function - End.
-- *srv6enc2sids*: Two SIDs (SRH present), two SR functions - End and
- End.DX6.
-- *srv6enc2sids-nodecaps*: Two SIDs (SRH present) without decapsulation,
- one SR function - End.
-- *srv6proxy-dyn*: Dynamic SRv6 proxy, one SR function - End.AD.
-- *srv6proxy-masq*: Masquerading SRv6 proxy, one SR function - End.AM.
-- *srv6proxy-stat*: Static SRv6 proxy, one SR function - End.AS.
-
-In all listed cases low number of IPv6 flows (253 per direction) is
-routed by VPP.
