New OpenFlow Message creation

Hello,

I want to send a python dictionary having IP, MAC correspondence from the controller to the switch in a new OpenFlow Message that I have created.
At the switch side, ofsoftswitch13 in this case, I will be handling them as an array of pointers to strings.
What would be the right way/data structure to send this correspondence down to the switch? should I send it in json format?

Thank you

you are right the configuration wasn't complete.
in the beginning when I executed ./boost.sh, I received many warnings like the following:
 src/Makefile.am:12:warning:source file 'built/component.cc' is in a subdirectory
src/Makefile.am:12:warning:source file 'builtin/connection-manager.cc' is in a subdirectory
automake: --------

These are annoying but I don't think they're problematic with current versions of autotools.

when I executed ../configure, I received the following error:
configure error: could not link against boost_system !

So you need to install boost development files.  I find it's easiest to just install all of them because if you try to do it one by one it's really easy to miss one.  So on Debian, I just do... I think it's apt-get install libboost-all-dev.

Good luck.

Sidenote: this discussion might be better aimed at the nox-dev mailing list on noxrepo.org.

Regarding openflow reference switch queue implementation

Hi all,

I'm experimenting on the openflow reference switch(userspace) with mininet.
I'm trying to get the number of packets currently queued at a switch, but what I've come to know is that each packet is passed through the whole path, than only next packet is being transmitted, so there is no possibility of the packets congestion, even if the bandwidth on any one link of the path is too low.

So does openflow reference switch works in this way only or is there something more to it?? 
Kindly let me know about this issue. It will be really helpful as i'm so much stuck at this problem right now.

Thanks & Regards,

Openflow for host

Hello,

Dear Openflow experts

I would like to ask you, is there an openflow for end user. 
I want the openflow controller communicate directly to the end user machine and modifies its flow-table.
I want the end user pc pretend as an OF switch and sends the packet-in message to the controller, then the
controller respond with the flow entry to the host.

I want your help to do so.

Best regards,
Amer

CFP :: SDWN 2015: 2nd International Conference on Software Defined and Virtualized Future Wireless Networks

(Apologies for duplicates)

### CALL FOR PAPERS ###

SDWN 2015: 2nd International Conference on Software Defined and
Virtualized Future Wireless Networks
Oct 26-27, 2015. Rome, Italy

Co-located with the IOT360 Summit. Endorsed by the European Alliance
for Innovation (EAI). http://iot-360.eu/2015/
Paper Submission Due Date: June 15, 2015

** Included in the Springer-LNICST and other indexing services **
http://sdnforwireless.org/2015/

SCOPE
=======================================

While the past few decades have witnessed the rapid growth in mobile
and wireless networks, numerous problems and challenges become
increasingly serious, such as heterogeneous wireless networks,
spectrum scarcity, smooth evolving and fast deployment, technologies
innovations, QoS and QoE support, etc. Traditional mobile and wireless
network technologies can hardly overcome these challenges.
Software-Defined Networking (SDN), an innovative paradigm, has become
one of the hottest topics in wired and wireless networking. SDN
advocates an effective separation of control plane and data planes,
providing new abstractions to both planes exposed through programmatic
interfaces. However, many challenges towards the realization of
Software-Defined Wireless Networks (SDWN) are still open, including
the end-to-end architecture, design and implementation of programmable
and virtualized wireless technologies, software defining strategies,
etc. At the same time, cloud computing and network virtualization are
considered as a promising way that benefits future wireless networks,
such as using the cloud computing resource pool providing powerful
computing capability to implement the baseband data processing of
wireless communication. However, how to design, customize, and utilize
the virtualization and cloud computing technologies targeted for the
wireless networks are still open problems.

Against this background, Software-Defined and Virtualized Future
Wireless Network is a new conference that aims to explore the new
design space, the new challenges and solutions, as well as new
applications and services of software-defined virtualized future
mobile and wireless networks. The goal of the conference is to solicit
original and inspiring research contributions from technology experts,
designers, researchers, and architects in academia and industry.
Bringing together practitioners and researchers to share knowledge,
experiences, and best practices.

TOPICS
=======================================

Topics of interests include, but are not limited to:
* New end-to-end mobile and wireless network architecture based on
SDWN, cloud computing, and virtualization technologies
* Cloud computing and network virtualization technologies for RAN,
backhaul and core networks
* Software-defined and abstracting strategies for network function and
air interface technologies in future wireless networks, including 5G
* Integration of SDNs with access networks and Evolved Packet Core,
including support for services such as handover
* Network Functions Virtualisation (NFV) & SDN applications and use cases
* QoS/E and traffic-awareness in SDWN
* Network management, monitoring and security as northbound APIs in SDWN
* Dynamic resource allocation in future wireless networks
* Immersive collaborative future wireless media
* Network evaluations and testbeds

PUBLICATION
=======================================

Papers will be published by Springer, LNICST. The proceedings are also
submitted for inclusion to the leading indexing services: DBLP, Google
Scholar, Thomson Scientific ISI Proceedings, EI Elsevier Engineering
Index, CrossRef, Scopus, as well as ICST's own EU Digital Library
(EUDL).
Selected papers will be published also in the EAI Endorsed
Transactions on Cloud Systems .

Highlights
* The event is endorsed by the European Alliance for Innovation, a
leading community-based organization devoted to the advancement of
innovation in the field of ICT and will be co-located with the IOT360
Summit;
* Participation in this event will give attendees the unique
opportunity to be exposed to all technical scientific aspects of IoT
related topic areas at co-located conferences, as well as be able to
have full access to the IoT market place and business aspects in
practice at the IOT 360 Summit.
* All accepted papers will be published by Springer and made available
through SpringerLink Digital Library, one of the world's largest
scientific libraries. Best papers will be invited to publish also in
the EAI Endorsed Transactions on Cloud Systems.

PAPER SUBMISSION
=======================================

Authors are invited to submit technical papers presenting original,
unpublished research, not currently under review elsewhere. All
submissions should be written in English with a maximum length of 8
pages, including all figures, tables, and references, in the PDF

Port status change behavior

Hi,

In my setup I am putting a link down (for example the link between s2
between 5) and from the controller I am seeing that the status of the
port are changing (port 1 for s5 and port 4 for s2).

What I am wondering is what happens if I am using port number 4 as an
outport in s5 in one of my tables? (since port 1 is down I was
thinking that maybe port 4 becomes port 3 but it wouldn't make much
sense...).

I am assuming that something is going wrong because I see many packets
disappearing when traversing s5 (I track it with wireshark).

Best,
Clément
