Device level iteration in RFC benchmark test cases

Device level iteration is used to utilize the maximum capacity of a FortiTester to test a single device under test (DUT).

The iteration either increases speed and connections or decreases them within pairs of ports. Alternatively, when using port level iteration, the change (increase or decrease) may not be the same within pairs of ports.

Device level iteration
Port Pair 1	Port pair 2	Change in next cycle: Port pair 1	Change in next cycle: Port pair 2
Loss Rate != 0	Loss Rate == 0	Decrease in speed or connections	Decrease in speed or connections
Loss Rate == 0	Loss Rate == 0	Increase in speed or connections	Increase in speed or connections

Port level iteration
Port Pair 1	Port pair 2	Change in next cycle: Port pair 1	Change in next cycle: Port pair 2
Loss Rate != 0	Loss Rate == 0	Decrease in speed or connections	Increase in speed or connections
Loss Rate == 0	Loss Rate == 0	Increase in speed or connections	Increase in speed or connections

Supported test cases

• FC2544 Throughput

• RFC2544 Latency

• RFC2544 Loss Rate

• RFC2544 Back to Back

• RFC3511 IP Throughput

• RFC3511 Concurrent TCP Connection Capacity

Creating a test case

To create a test case using device level iteration:

1. Select one of the supported case types. In this example, RFC2544 Throughput.

   

2. Choose the IP version and DUT working mode, then click OK. In this example, IP Version is V4 and DUT Working Mode is Network Address Translation (NAT).

   

3. In Iteration Level, select Device, then click Start to start the test case.

   

4. Review the results.

   In the port1-port3 pair, the loss rate is always not equal to zero. Therefore, its load is decreased.

   In the port2-port4 pair, starting from cycle five, the loss rate is zero, but the change is still to decrease as the port1-port3 pair has a non-zero loss rate.
