Internet Protocol Security (IPsec)¶
VPP IPsec performance tests are executed for the following crypto plugins:
crypto_native, used for software based crypto leveraging CPU platform optimizations e.g. Intel’s AES-NI instruction set.
crypto_ipsecmb, used for hardware based crypto with Intel QAT PCIe cards.
IPsec with VPP Native SW Crypto¶
Currently CSIT-2101 implements following IPsec test cases relying on VPP native crypto (crypto_native plugin):
VPP Crypto Engine |
ESP Encryption |
ESP Integrity |
Scale Tested |
|---|---|---|---|
crypto_native |
AES[128|256]-GCM |
GCM |
1 to 60k tunnels |
crypto_native |
AES128-CBC |
SHA[256|512] |
1 to 60k tunnels |
VPP IPsec with SW crypto are executed in both tunnel and policy modes, with tests running on 3-node testbeds: 3n-hsw and 3n-skx.
IPsec with Intel QAT HW¶
Currently CSIT-2101 implements following IPsec test cases relying on ipsecmb library (crypto_ipsecmb plugin) and Intel QAT 8950 (50G HW crypto card):

VPP IPsec with HW crypto are executed in both tunnel and policy modes, with tests running on 3-node Haswell testbeds (3n-hsw), as these are the only testbeds equipped with Intel QAT cards.
