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.

        We done the test repeated by different number of switches with the sequence of 500、1000、1500、2000 ……

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. 

Preparation

        1、Features install

                onos-drivers、onos-openflow-base、onos-openflow

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).

        2、Start the controller with the features install.

        3、Start the capture of IxNetwork ports.

        4、Start all of the OF protocol of the switches simultaneous.

        5、Wait until all of the channels are established and Echo message interaction started，then stop the capture.If all of the sessions can't be established in 5 minutes means the controller can't support those OF channels.

        6、If step 5 is successful, then wait for 5 minutes and check whether the established channels are stable without any flap, and the Echo messages sent are equal with received. 

        7、if step 6 has passed,
