barrier_request sent to lagopus but no reply barrier_reply #15

Open monstery opened 10 years ago

monstery commented 10 years ago

lagopus run on 4-core atom CPU and 8-core atom CPU We start lagopus with the following command:

lagopus -d -- -cff -n2 -- -p3f

We will set 6 flows to our lagopus softswitch by Ryu controller. The flows are as follows:

  1. priority=65535, in_port=1, output=2
  2. priority=65535, in_port=2, output=1
  3. priority=65535, in_port=3, output=4
  4. priority=65535, in_port=4, output=3
  5. priority=65535, in_port=5, output=6
  6. priority=65535, in_port=6, output=5

port 1 connect our traffic generator port 16 port 2 connect our traffic generator port 17 port 3 connect our traffic generator port 18 port 4 connect our traffic generator port 19

we do Ryu test. The ryu test will always report barrier-reply time out error.
