Hello,
I just got into the domain of SDNs.
I am having difficulty trying to understand some basic concept like
the following:
I am currently running all my experiments and modifications on the
Mininet platform.
Is the *user switch(Stanford's code)* source code in the folder called
"openflow" in mininet? (~/openflow/udatapath/ )
I want to do some modification to the switch's implementation.
So I downloaded the source code from "*openflow.org
<http://openflow.org/>*" and made couple of modification(couple of
print statements) and pushed the code on mininet and ran it. It worked!
*Question1: Is my assumption that stanford's switch source code in
"openflow" folder right? **If my assumption is wrong, please give me
some pointers.*
This is right. It's the openflow 1.0 reference implementation (from
Stanford).
*Question 2: I want to do some modification to the table flow and I
want the "Multi table", "goto-table" instructions for the modification
that i want to make.*
*So is there an implementation for "Multi table flow" in Stanford's
code? If so , can you please guide me.
*
*I know there is for OVS 1.11.0 but I have time constraint and I feel
the user switch implementation is smaller and I can implement it
faster on the user switch code.*
As far as i got it from the code the reference implementation does only
include 2 different tables: one wildcard flow table and one exact match
table. The first table finding a match is executed.
If i remember correctly, goto-table is not is feature of OpenFlow 1.0,
right?
Best,
Philip
Thanks in advance.
