Objet : Re: [Ryu-devel] [SUPER SUPER URGENT FOR THESIS] RYU Queues!!
Hi Sherif,
If Queue ID is correct (exists), it should work as expected.
I will fix this bug of rest_qos.py, but for workaround, please use "ovs-vsctl"
command
to confirm Queue ID.
For example, "qos" value in Port table is corresponding to "_uuid" of QoS
table, and
key of queues set in QoS table is corresponding to Queue ID.
# "f92839ae-58fc-4e6f-baee-c0bafd45f892" is corresponding to "_uuid" of QoS
table
mininet> sh ovs-vsctl list Port s1-eth1
...(snip)...
name : "s1-eth1"
...(snip)...
qos : f92839ae-58fc-4e6f-baee-c0bafd45f892
...(snip)...
# QoS "f92839ae-58fc-4e6f-baee-c0bafd45f892" has two Queues:
# - 0: 7b4fcc2d-71fd-4ab6-9399-b6da84e2e1a0
# - 1: aaf1000d-7574-451d-b1fb-bdb4cd8e029
mininet> sh ovs-vsctl list QoS
_uuid : f92839ae-58fc-4e6f-baee-c0bafd45f892
external_ids : {}
other_config : {max-rate="1000000"}
queues : {0=7b4fcc2d-71fd-4ab6-9399-b6da84e2e1a0,
1=aaf1000d-7574-451d-b1fb-bdb4cd8e029f}
type : linux-htb
# Details for each Queue
mininet> sh ovs-vsctl list Queue
_uuid : 7b4fcc2d-71fd-4ab6-9399-b6da84e2e1a0
dscp : []
external_ids : {}
other_config : {max-rate="500000"}
_uuid : aaf1000d-7574-451d-b1fb-bdb4cd8e029f
dscp : []
external_ids : {}
other_config : {min-rate="800000"}
Thanks,
Iwase
