There are multiple ways that you can set up in-band control, and I believe
support varies depending on the specific type of switch you're using, so you
will probably get a better response by asking the specific switch vendor.

What you're really talking about here is changing OpenFlow. OpenFlow is a
standard, meaning any changes should go through the Open Networking Foundation
(who maintains the standard). Any changes you make will make your program
incompatible with other switches that implement the OpenFlow protoc

When a switch gets a packet that doesn't correspond to an entry in the flow
tables, it will generally buffer it and associate this buffer with an opaque
buffer identifier. It will then send a packet_in message to the controller
that includes the buffer ID and *part* of the packet data itsel
The machine running NOX does not need to be *directly* connected to the

Yes, you can do this. Take a look at the OpenFlow 1.0 specification;

Basically, you send a stats request with the type set to OFPST_FLOW and the

Though offhand, I don't know what I can tell you. What do mean by unreachable?

This depends on exactly what you mean, though I wonder if you are operating
under a misconception.
If you use NOX to install a flow with, for example, an OFPAT_SET_DL_DST action
to set the ethernet address... the actual work of rewriting the packet header
happens on the switch. It's only the i
Maybe some of these resources will be useful?

Sorry, but it's in seconds. (See ofp_flow_mod in the OpenFlow spec.)

I don't really know anything about mobilevms, and I suspect this may be one of
the cases where SWIG is misleading about what's going on. But for starters,
why don't you try...

How do the switches crash? With an assertion about insufficient buffer
headroom or something? Or about a bad buffer ID (are you applying multiple
actions?)? Or do they just segfault?
Feel free to send along a capture of the OpenFlow traffic between NOX and the
switch (along with the NOX and

pyswitch is intended to be a very simple demo and does something along the
lines of making each switch in the network a standalone L2 learning switch.
Each switch gets no insight about the topology from its neighbors. routing
actually uses a global view of the topology, and can just generate o

A function in Python is a first class object. In the code below, f is defined
inside of gen_datapath_join_callback, and you get a new f. Since a function is
just an object, gen_datapath_join_callback then adds a new property to f -- the
cb property. Inside f, this property is accessed.
