"Multi Learning Switch" sample application

In order to learn how to implement software L2 switch (multiple switch support)
As a developer using Trema
I want to execute "Multi Learning Switch" sample application

Background

Given

a file named "multi_learning_switch.conf" with:

vswitch("multi_learning1") { datapath_id "0x1" }
vswitch("multi_learning2") { datapath_id "0x2" }
vswitch("multi_learning3") { datapath_id "0x3" }
vswitch("multi_learning4") { datapath_id "0x4" }

vhost("host1")
vhost("host2")
vhost("host3")
vhost("host4")

link "multi_learning1", "host1"
link "multi_learning2", "host2"
link "multi_learning3", "host3"
link "multi_learning4", "host4"
link "multi_learning1", "multi_learning2"
link "multi_learning2", "multi_learning3"
link "multi_learning3", "multi_learning4"

Scenarios

@slow_process Run "Multi Learning Switch" C example

Given

I run trema run ../../objects/examples/multi_learning_switch/multi_learning_switch -c multi_learning_switch.conf -d

And

wait until "multi_learning_switch" is up

When

I send 2 packets from host1 to host2

Then

the total number of tx packets should be:

host1	host2	host3	host4
2	0	0	0

And

the total number of rx packets should be:

host1	host2	host3	host4
0	2	0	0

When

I send 3 packets from host3 to host4

Then

the total number of tx packets should be:

host1	host2	host3	host4
2	0	3	0

And

the total number of rx packets should be:

host1	host2	host3	host4
0	2	0	3

When

I send 2 packets from host4 to host1

Then

the total number of tx packets should be:

host1	host2	host3	host4
2	0	3	2

And

the total number of rx packets should be:

host1	host2	host3	host4
2	2	0	3

When

I send 4 packets from host2 to host3

Then

the total number of tx packets should be:

host1	host2	host3	host4
2	4	3	2

And

the total number of rx packets should be:

host1	host2	host3	host4
2	2	4	3

When

I send 1 packets from host1 to host4

Then

the total number of tx packets should be:

host1	host2	host3	host4
3	4	3	2

And

the total number of rx packets should be:

host1	host2	host3	host4
2	2	4	4

@slow_process Run "Multi Learning Switch" Ruby example

Then

the total number of tx packets should be:

host1	host2	host3	host4
2	0	0	0

And

the total number of rx packets should be:

host1	host2	host3	host4
0	2	0	0

When

I send 3 packets from host3 to host4

Then

the total number of tx packets should be:

host1	host2	host3	host4
2	0	3	0

And

the total number of rx packets should be:

host1	host2	host3	host4
0	2	0	3

When

I send 2 packets from host4 to host1

Then

the total number of tx packets should be:

host1	host2	host3	host4
2	0	3	2

And

the total number of rx packets should be:

host1	host2	host3	host4
2	2	0	3

When

I send 4 packets from host2 to host3

Then

the total number of tx packets should be:

host1	host2	host3	host4
2	4	3	2

And

the total number of rx packets should be:

host1	host2	host3	host4
2	2	4	3

When

I send 1 packets from host1 to host4

Then

the total number of tx packets should be:

host1	host2	host3	host4
3	4	3	2

And

the total number of rx packets should be:

host1	host2	host3	host4
2	2	4	4
