Using IPSec bench "Equilibrium throughput" method

Once done, we start using a fast method for measuring the “IPsec equilibrium throughput” of the DUT.

Notice that the reference device (IBM x3550-M3) used in front of the Netgate has a equilibrium throughput of 843Mb/s. Then if the value measured during this bench is close to 843Mb/s we had to found a more powerful reference device.

From the packet generator/receiver a simple script that use netmap-pktgen will do the job:

[root@R1]~# equilibrium -u -4 -d 00:08:a2:09:33:da -t igb2 -r igb3
Benchmark tool using equilibrium throughput method
- Benchmark mode: Bandwitdh (bps) for VPN gateway
- UDP load = 500B, IPv4 packet size=528B, Ethernet frame size=542B
- Link rate = 1000 Mb/s
- Tolerance = 0.01
Iteration 1
  - Offering load = 500 Mb/s
  - Step = 250 Mb/s
  - Measured forwarding rate = 399 Mb/s
Iteration 2
  - Offering load = 250 Mb/s
  - Step = 250 Mb/s
  - Trend = decreasing
  - Measured forwarding rate = 250 Mb/s
Iteration 3
  - Offering load = 375 Mb/s
  - Step = 125 Mb/s
  - Trend = increasing
  - Measured forwarding rate = 375 Mb/s
Iteration 4
  - Offering load = 437 Mb/s
  - Step = 62 Mb/s
  - Trend = increasing
  - Measured forwarding rate = 399 Mb/s
Iteration 5
  - Offering load = 406 Mb/s
  - Step = 31 Mb/s
  - Trend = decreasing
  - Measured forwarding rate = 399 Mb/s
Iteration 6
  - Offering load = 391 Mb/s
  - Step = 15 Mb/s
  - Trend = decreasing
  - Measured forwarding rate = 391 Mb/s
Iteration 7
  - Offering load = 398 Mb/s
  - Step = 7 Mb/s
  - Trend = increasing
  - Measured forwarding rate = 398 Mb/s
Estimated Equilibrium Ethernet throughput= 398 Mb/s (maximum value seen: 399 Mb/s)

Using AES-GCM-128 and aesni kernel module loaded on the NetGate RCC-VE 4860, we can estimate an IPSec Equilibrium throughput of about 400Mb/s.
