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-release| 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-release| implements following IPsec test cases relying
on ipsecmb library (`crypto_ipsecmb` plugin) and Intel QAT 8950 (50G HW
crypto card):
dpdk_cryptodev
+-------------------+---------------------+------------------+----------------+------------------+
| VPP Crypto Engine | VPP Crypto Workers | ESP Encryption | ESP Integrity | Scale Tested |
+===================+=====================+==================+================+==================+
| crypto_ipsecmb | sync/all workers | AES[128|256]-GCM | GCM | 1, 1k tunnels |
+-------------------+---------------------+------------------+----------------+------------------+
| crypto_ipsecmb | sync/all workers | AES[128]-CBC | SHA[256|512] | 1, 1k tunnels |
+-------------------+---------------------+------------------+----------------+------------------+
| crypto_ipsecmb | async/crypto worker | AES[128|256]-GCM | GCM | 1, 4, 1k tunnels |
+-------------------+---------------------+------------------+----------------+------------------+
| crypto_ipsecmb | async/crypto worker | AES[128]-CBC | SHA[256|512] | 1, 4, 1k tunnels |
+-------------------+---------------------+------------------+----------------+------------------+
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.
