Feature: control multiple openflow switchies using routing_switch
As a Trema user
I want to control multiple openflow switches using routing_switch application
So that I can send and receive packets
Scenario: One openflow switch, two servers
When I try trema run "../apps/routing_switch/routing_switch" with following configuration (backgrounded):
"""
vswitch("switch1") { datapath_id "0xabc" }
vhost("host1")
vhost("host2")
link "switch1", "host1"
link "switch1", "host2"
run { path "../apps/topology/topology" }
run { path "../apps/topology/topology_discovery" }
event :port_status => "topology", :packet_in => "filter", :state_notify => "topology"
filter :lldp => "topology_discovery", :packet_in => "routing_switch"
"""
And wait until "routing_switch" is up
And *** sleep 15 ***
And I send packets from host1 to host2 (duration = 10)
And I try to run "./trema show_stats host1 --tx" (log = "tx.host1.log")
And I try to run "./trema show_stats host2 --rx" (log = "rx.host2.log")
Then the content of "tx.host1.log" and "rx.host2.log" should be identical
And I send packets from host2 to host1 (duration = 10)
And I try to run "./trema show_stats host2 --tx" (log = "tx.host2.log")
And I try to run "./trema show_stats host1 --rx" (log = "rx.host1.log")
Then the content of "tx.host2.log" and "rx.host1.log" should be identical
Scenario: restart openflow switch
