Hello,
I've working with MPTCP protocol and I need access the OPTIONS field
from TCP protocol. How can I access the OPTIONS field, using tcp_opt class?
cheers,

Hello Lucas,
MPTCP it is a extension for multipath in TCP
protocol. MPTCP divides a single TCP socket into many concurrent TCP
sockets. Each TCP socket created by MPTCP is called subflow.

I think you can do this with deep packet inspection, then you could
compress and "re-build" your packet. But I saying this, thinking that you
are thinking in use algorithms such as:

correct?

I don't know any special function on POX to do that, but you could use
native python methods.
ip = '10.0.0.1'
ip_list = ip.split('.') # split() method will split values into a list.
print ip_list

It was introduced a component which allows hypervisor (l2_flowvisor) and a
lot components in pox/misc, such as fullpayload.py, which allows you do DPI.

Hello All,
Problem in storing values in data-structures
Hello All,
I'm trying to store values into data structures, specifically lists. I've
tried to use Append() method to append new values in my list as always. But
as far as I know, when I run the controller, it just store values

Hello,
For receive packets statistics, I guess you can use SFlow to
measure that.

Hello,
Is that possible set a match and action without in_port and/or
out_port argument?
Hi,
I'm using manual rules in my code, to match it packets from tcp
ports... I'm forwarding non tcp packets as conventional of.OFPP_NORMAL.
When a packet is tcp, I'm filtering and after that using the following
steps:
match = of.ofp_match()
match.tp_src = pa

You told "I can't ping to controller either". Did you check

Hello,
Why don't you use l2_multi? It uses spanning tree, and if you want a
backup path when a link is down it works very well. However, if you are
looking for a packet replay, remember that you need see if there's host
support (in case of UDP, you can search a paper called "n-cast" or in c

Hello,
If you are looking for robustness, you must know that there is an
hypervisor called Flowvisor used to divide network into slices for
processing flows in distincts controllers. As an example with 4
controllers, you can set one for processing TCP, another for UDP, etc.
Further, you can also s
