Hello all, I'm a newbie to openflow/ovs, and I have some questions regarding the hardware performance implementing Openflow. I got some experimental data below from some scientific reports( http://staff.science.uva.nl/~delaat/rp/2011-2012/p18/report.pdf, et al): (Varing with different platforms, mainly focuses on the commercial switches) The maximum number of flows that can be installed in the flow table is around 100k; The time cost for installing single flow is about 1~6ms which means that intalling millions of flows may cost hundreds seconds. Does it means that recent openflow switches are still not applicable for the arduous cases of the large scale network, e.g the load balancing service for the web server cluster since the concurrent traffic may reach millions requests per second, and the hardware performance above is seriously unacceptable. Thanks, Regards, Ryan
