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. |
