AFAIK, the OpenFlow Spec does not mention about the memory usage or allocation on the OpenFlow switch. "OpenFlow" defines just protocol between switch and controller, and some requirements for switch interfaces. So, does not mention about implementations. >> Have you tried to contact your switch's team? > > I am working alone, it is for my personal use and interest, and I was > looking for something general which can be true for most of the available > switches FYI, Ryu provides the "OpenFlow Switch Test Tool". http://osrg.github.io/ryu-book/en/html/switch_test_tool.html This test suite checks the compatibility of the OpenFlow switches and ouputs the reports. http://osrg.github.io/ryu/certification.html Thanks, Iwase > > On Fri, Dec 2, 2016 at 1:02 AM, Iwase Yusuke <iwase.yusu...@gmail.com> > wrote: > >> Hi, >> >> Hummm... it is depending on the implementation of your switch, I guess. >> >> The length of the OpenFlow messages in bytes can be retried from >> ofp_header, >> but how to allocate memory for those rules is not mentioned on the OpenFlow >> Spec. >> >> Have you tried to contact your switch's team? >> >> Thanks, >> Iwase >> >> >> On 2016年11月28日 21:50, Moh'd Reza Abbasi wrote: >> >>> Hello all, >>> I am new to SDN and Ryu controller world, so I have couple of questions: >>> >>> 1.
