Description

      The purpose of the test is to measure the performance of OpenFlow controller channels with a single or cluster controllers. Multiple switches are setuped up by IxNetwork, and directly connected to controllers by TCP connection.   

...

      For cluster mode, we done the test repeated by different number of switches with the sequence of 100、200、300、400 ……

Suggestions

1. If the OF sessions are restricted to 1000 or 1024, please check the following points:
   

   a) DPID configured by IxNetwork, they should exclusive with each switch.

   b) File descriptor of the OS which running the controllers(default with 1024).

   c)  ARP tables volume of the OS which running the controllers(default with 1024).

2. In order to test out the best performance of controllers, several ports of IxNetwork are suggested. In the test below, we used four ports to do the test, each ports with same number of switches, forexample, 500 switches test, we configed 125 switches each port.

Preparation

1. Features install

   Code Block
   onos> feature:install onos-drivers onos> feature:install onos-openflow onos> feature:install onos-openflow-base

Test steps

      1. Config IxNetwork with multiple switches equally by four ports (first time with 500).

...

      9. Restart the test with another number of switches.
