4 VPP is tested in a number of L2 and IP packet lookup and forwarding
5 modes. Within each mode baseline and scale tests are executed, the
6 latter with varying number of lookup entries.
11 VPP is tested in three L2 forwarding modes:
13 - *l2patch*: L2 patch, the fastest point-to-point L2 path that loops
14 packets between two interfaces without any Ethernet frame checks or
16 - *l2xc*: L2 cross-connect, point-to-point L2 path with all Ethernet
17 frame checks, but no MAC learning and no MAC lookup.
18 - *l2bd*: L2 bridge-domain, multipoint-to-multipoint L2 path with all
19 Ethernet frame checks, with MAC learning (unless static MACs are used)
22 l2bd tests are executed in baseline and scale configurations:
24 - *l2bdbase*: low number of L2 flows (254 per direction) is switched by
25 VPP. They drive the content of MAC FIB size (508 total MAC entries).
26 Both source and destination MAC addresses are incremented on a packet
29 - *l2bdscale*: high number of L2 flows is switched by VPP. Tested MAC
30 FIB sizes include: i) 10k (5k unique flows per direction), ii) 100k
31 (2x 50k flows) and iii) 1M (2x 500k). Both source and destination MAC
32 addresses are incremented on a packet by packet basis, ensuring new
33 entries are learn refreshed and looked up at every packet, making it
34 the worst case scenario.
36 Ethernet wire encapsulations tested include: untagged, dot1q, dot1ad.
41 IPv4 routing tests are executed in baseline and scale configurations:
43 - *ip4base*: low number of IPv4 flows (253 or 254 per direction) is routed by
44 VPP. They drive the content of IPv4 FIB size (506 or 508 total /32 prefixes).
45 Destination IPv4 addresses are incremented on a packet by packet
48 - *ip4scale*: high number of IPv4 flows is routed by VPP. Tested IPv4
49 FIB sizes of /32 prefixes include: i) 20k (10k unique flows per
50 direction), ii) 200k (2x 100k flows) and iii) 2M (2x 1M). Destination
51 IPv4 addresses are incremented on a packet by packet basis, ensuring
52 new FIB entries are looked up at every packet, making it the worst
58 IPv6 routing tests are executed in baseline and scale configurations:
60 - *ip6base*: low number of IPv6 flows (253 or 254 per direction) is routed by
61 VPP. They drive the content of IPv6 FIB size (506 or 508 total /128 prefixes).
62 Destination IPv6 addresses are incremented on a packet by packet
65 - *ip6scale*: high number of IPv6 flows is routed by VPP. Tested IPv6
66 FIB sizes of /128 prefixes include: i) 20k (10k unique flows per
67 direction), ii) 200k (2x 100k flows) and iii) 2M (2x 1M). Destination
68 IPv6 addresses are incremented on a packet by packet basis, ensuring
69 new FIB entries are looked up at every packet, making it the worst
75 SRv6 routing tests are executed in a number of baseline configurations,
76 in each case SR policy and steering policy are configured for one
77 direction and one (or two) SR behaviours (functions) in the other
80 - *srv6enc1sid*: One SID (no SRH present), one SR function - End.
81 - *srv6enc2sids*: Two SIDs (SRH present), two SR functions - End and
83 - *srv6enc2sids-nodecaps*: Two SIDs (SRH present) without decapsulation,
84 one SR function - End.
85 - *srv6proxy-dyn*: Dynamic SRv6 proxy, one SR function - End.AD.
86 - *srv6proxy-masq*: Masquerading SRv6 proxy, one SR function - End.AM.
87 - *srv6proxy-stat*: Static SRv6 proxy, one SR function - End.AS.
89 In all listed cases low number of IPv6 flows (253 per direction) is
