Hello I have created QoS classes, and am able to separate the traffic based on source address. What I want to do now is enable QoS classes only when link is congested. For example, if there are 3 hosts, h1, h2, h3, connected by single switch s1. Suppose h1 is sending file to h3. Simultaneously h2

Got it. Thank you. OFPXMT_OFB_METADATA would also work for my goal. But tests show that metadata is not sent as well.  On switch: $ sudo ovs-ofctl -O OpenFlow13 dump-flows s2 OFPST_FLOW reply (OF1.3) (xid=0x2): cookie=0x0, duration=12.958s, table=0, n_packets=0, n_bytes=0, priority=1,udp,tp_ds

It won't work because flow-mod and packet-out aren't going to use the same xid as the packet-in. On Fri, May 13, 2016 at 12:07:58PM +, Ali Volkan Atli wrote: > Currently, I can buffer packets for each flow, then send only one > packet-in message to controllers, now I'm trying to figure out how

Hi Ben Currently, I can buffer packets for each flow, then send only one packet-in message to controllers, now I'm trying to figure out how to match the packet-in with flow-mod or packet-out? If I use xid to match packet-in and flow-mod or packet-out, does it violate specs? - Volkan _
