IPSec benchmark "Equilibrium throughput" method

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

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

[root@pkt-gen]~# equilibrium -4 -d 00:07:43:2e:e5:90 -t vcxl0 -r vcxl1 -l 10000
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 = 10000 Mb/s
- Tolerance = 0.01
Iteration 1
  - Offering load = 5000 Mb/s
  - Step = 2500 Mb/s
  - Measured forwarding rate = 1598 Mb/s
  - Forwared rate too low, forcing OLOAD=FWRATE and STEP=FWRATE/2
Iteration 2
  - Offering load = 1598 Mb/s
  - Step = 799 Mb/s
  - Trend = decreasing
  - Measured forwarding rate = 1597 Mb/s
Iteration 3
  - Offering load = 1997 Mb/s
  - Step = 399 Mb/s
  - Trend = increasing
  - Measured forwarding rate = 1602 Mb/s
Iteration 4
  - Offering load = 1798 Mb/s
  - Step = 199 Mb/s
  - Trend = decreasing
  - Measured forwarding rate = 1599 Mb/s
Iteration 5
  - Offering load = 1699 Mb/s
  - Step = 99 Mb/s
  - Trend = decreasing
  - Measured forwarding rate = 1600 Mb/s
Iteration 6
  - Offering load = 1650 Mb/s
  - Step = 49 Mb/s
  - Trend = decreasing
  - Measured forwarding rate = 1603 Mb/s
Iteration 7
  - Offering load = 1626 Mb/s
  - Step = 24 Mb/s
  - Trend = decreasing
  - Measured forwarding rate = 1604 Mb/s
Estimated Equilibrium Ethernet throughput= 1604 Mb/s (maximum value seen: 1604 Mb/s)

⇒ We reach about 1.604Gb/s to encrypt 5000 flows.
