Yes. It should be the same result. Because "priority" means the priority of the flow entry. In this test, even if set to any value the "priority", should not affect the result. > And I still have two more questions, > does your QoS mechanism have the priority function? For example, > server bandwidth is allocated by the clients based on their priority ? I have attached an overview of my proposed method. I think that server bandwidth is allocated by the clients priority. > And what's the major difference between the priority of flow > entry(7.3.4.1 Modify Flow Entry Message) > and the priority of QoS mechanism mentioned in the Ryu Online > documentation_QoS Chapter? >the priority of QoS mechanism mentioned in the Ryu Online documentation_QoS >Chapter?

If this point, https://github.com/osrg/ryu-book/blame/master/ja/source/rest_qos.rst#L222 This point means the priority of the flow entry. > I would appreciate your kind help!! > > > > > > > 2014-12-11 10:08 GMT+08:00 Minoru TAKAHASHI <[email protected] > <mailto:[email protected]>>: > > Hi,Json > > >However, in terms of priority values, port 5002 was supposed to have the > higher priority value and occupy the bandwidth but its bandwidth dropped at > >t = 4 after the client 1(port 5001, priority = 1) made a request of data. > >It seemed that the priority setting didn’t work at all. > > curl -X POST -d '{"priority":"3", > "match": {"nw_dst": "10.0.0.1", "nw_proto": "UDP", > "tp_dst": "5002"}, > "actions":{"queue": "0"}}' > http://localhost:8080/qos/rules/0000000000000001 > > "priority" of this command means that matching precedence of the flow > entry. > (Please check "7.3.4.1 Modify Flow Entry Message" of OFSpec 1.3.4.) > Therefore, there is no related to priority of QoS. > > >Therefore, could you provide me a testing approach to verify the > priority mechanism? > > If you want to treat CL2 as a high priority than CL1, > For example, Why do not try to set as follows? > > Change before (current)) > port 5001 (CL1) -> Set to Queue 0 (max_rate: 0.85M bits / sec) > port 5002 (CL2) -> Set to Queue 0 (max_rate: 0.85M bits / sec) > > After the change) > port 5001 (CL1) -> Set to Queue 0 (max_rate: 0.2M bits / sec) > port 5002 (CL2) -> Set to Queue 1 (min_rate: 0.85M bits / sec) > > The result should be as follows: > * The traffic sent to the port 5001 is shaped with up to 200Kbps. > * The traffic sent to the port 5002 is guaranteed 850Kbps bandwidth. > > On 2014年12月10日 13:52, 許東豐 wrote: > > To whom it may concern: > > My name is Jason.
