Hi, I have created a topology with mininet. When I've added the links, I've used the delay parameter, as in self.addLink( node1, node2, delay='5ms'). After running the topology with sudo mn --custom topo5g.py --topo topo5g --switch ovsk --controller remote --mac --arp --link tc
I have created a qos for a switch and I have added the flows to force traffic to go through these queues, like this: sudo ovs-vsctl -- set Port s1-eth1 qos=@newqos -- set Port s1-eth2 qos=@newqos -- --id=@newqos create QoS type=linux-htb other-config:max-rate=100000 queues=0=@q0,1=@q1 -- --id=@q0 create Queue other-config:min-rate=100000 other-config:max-rate=100000 -- --id=@q1 create Queue other-config:min-rate=1000 other-config:max-rate=1000 sudo ovs-ofctl add-flow s1 in_port=2,dl_type=0x0800,nw_proto=6,nw_src=10.0.0.8,nw_dst=10.0.0.4,tp_src=333,priority=100,actions=enqueue:1:1 sudo ovs-ofctl add-flow s1 in_port=1,dl_type=0x0800,nw_proto=6,nw_src=10.0.0.4,nw_dst=10.0.0.8,tp_dst=333,priority=100,actions=enqueue: However, when I use sudo ovs-ofctl queue-stats s1, I obtain this answer: OFPST_QUEUE reply (xid=0x2): 0 queues. And obviously the QoS does not work. This does not happen when I don't use the delay parameter in mininet. If I don't define a delay in mininet, the queues exist and the QoS works fine. Why is that? Can't I have queues and control delay at the same time?
