-VPP Forwarding Modes
---------------------
-
-VPP is tested in a number of L2 and IP packet lookup and forwarding
-modes. Within each mode baseline and scale tests are executed, the
-latter with varying number of lookup 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*: low number of L2 flows (254 per direction) is switched by
- VPP. They drive the content of MAC FIB size (508 total MAC entries).
- Both source and destination MAC addresses are incremented on a packet
- by packet basis.
-
-- *l2bdscale*: high number of L2 flows is switched by VPP. Tested MAC
- FIB sizes include: i) 10k (5k unique flows per direction), ii) 100k
- (2x 50k flows) and iii) 1M (2x 500k). Both source and destination MAC
- addresses are incremented on a packet by packet basis, ensuring new
- entries are learn refreshed and looked up at every packet, making it
- the worst case scenario.
-
-Ethernet wire encapsulations tested include: untagged, dot1q, dot1ad.
-
-IPv4 Routing
-~~~~~~~~~~~~
-
-IPv4 routing tests are executed in baseline and scale configurations:
-
-- *ip4base*: low number of IPv4 flows (253 or 254 per direction) is routed by
- VPP. They drive the content of IPv4 FIB size (506 or 508 total /32 prefixes).
- Destination IPv4 addresses are incremented on a packet by packet
- basis.
-
-- *ip4scale*: high number of IPv4 flows is routed by VPP. Tested IPv4
- FIB sizes of /32 prefixes include: i) 20k (10k unique flows per
- direction), ii) 200k (2x 100k flows) and iii) 2M (2x 1M). Destination
- IPv4 addresses are incremented on a packet by packet basis, ensuring
- new FIB entries are looked up at every packet, making it the worst
- case scenario.
-
-IPv6 Routing
-~~~~~~~~~~~~
-
-IPv6 routing tests are executed in baseline and scale configurations:
-
-- *ip6base*: low number of IPv6 flows (253 or 254 per direction) is routed by
- VPP. They drive the content of IPv6 FIB size (506 or 508 total /128 prefixes).
- Destination IPv6 addresses are incremented on a packet by packet
- basis.
-
-- *ip6scale*: high number of IPv6 flows is routed by VPP. Tested IPv6
- FIB sizes of /128 prefixes include: i) 20k (10k unique flows per
- direction), ii) 200k (2x 100k flows) and iii) 2M (2x 1M). Destination
- IPv6 addresses are incremented on a packet by packet basis, ensuring
- new FIB entries are looked up at every packet, making it the worst
- case scenario.
-
-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.
