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.   

        There are two items we should measure: 1、The established time of these switches; 2、The maximum number of OF channels can be support coinstantaneous by controllers.

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.
