Hi , Ben Thanks for your reply.
I configured the bond0 using linux bond then the result is not good for minimum guaranteed bandwidth. But if I use ovs-vsctl add-bond to configure the bond0 interface, the result is good. If I use linux bond with linux tc, the tc works well also. However, most problems with QoS on Linux are not bugs in Open vSwitch at all. They tend to be either configuration errors (please see the earlier questions in this section) or issues with Could you send me the section link? Thanks. 在 2016年7月2日，上午8:31，Ben Pfaff <b...@ovn.org<mailto:b...@ovn.org>> 写道： On Fri, Jul 01, 2016 at 03:40:30AM +0000, Xiao Ma (xima2) wrote: I want to use the QoS feature of OpenvSwitch to control the bandwidth based on the vlan id(Scene 1) or port id(Scene 2). So I deployed it as showed bellow,and configured the qos rules,the flows,and used iperf tool to test it. But the result is disappointment. Are you confident that this is actually an OVS problem and not a problem with the Linux kernel HTB code? The FAQ says: ### Q: I configured QoS, correctly, but my measurements show that it isn't working as well as I expect. A: With the Linux kernel, the Open vSwitch implementation of QoS has two aspects: - Open vSwitch configures a subset of Linux kernel QoS features, according to what is in OVSDB. It is possible that this code has bugs. If you believe that this is so, then you can configure the Linux traffic control (QoS) stack directly with the "tc" program. If you get better results that way, you can send a detailed bug report to b...@openvswitch.org<mailto:b...@openvswitch.org>. It is certain that Open vSwitch cannot configure every Linux kernel QoS feature. If you need some feature that OVS cannot configure, then you can also use "tc" directly (or add that feature to OVS). - The Open vSwitch implementation of OpenFlow allows flows to be directed to particular queues. This is pretty simple and unlikely to have serious bugs at this point. However, most problems with QoS on Linux are not bugs in Open vSwitch at all. They tend to be either configuration errors (please see the earlier questions in this section) or issues with the traffic control (QoS) stack in Linux. The Open vSwitch developers are not experts on Linux traffic control. We suggest that, if you believe you are encountering a problem with Linux traffic control, that you consult the tc manpages (e.g. tc(8), tc-htb(8), tc-hfsc(8)), web resources (e.g. http://lartc.org/), or mailing lists (e.g. http://vger.kernel.org/vger-lists.html#netdev).
