First EWSDN HandsOn / Hackathon on ONOS - September 28th-29th 2015 in Bilbao

Dear Colleagues

It's my pleasure to invite you to the First European Workshop on Software Defined Networks HandsOn /
Hackathon, that will be held September 28th-29th 2015 in Bilbao, on the same venue and just before the 4th
European Workshop on Software Defined Networks.

The European Workshop on Software Defined Networks has always been characterized by treating both
scientific, industrial and practical topics through the regular, poster and demo track. Having the
possibility of acquiring first hand knowledge from the authors of available Open Source software is an
addition that we think will foster your interest in the EWSDN event.

It has been difficult to make a choice and decide either to concentrate all the event to one product or
present several complementary or competing products. Our previous experience decided us to target only
one product and have a HandsOn/Tutorial for the the first day and a Hackathon for the second one. We think
this approach will cover expectations from everybody, novel and experienced users.

This year, we have chosen ONOS, which defines itself as "a new carrier-grade SDN network operating system
designed for high availability, performance, scale-out." ONOS is maturing quite quickly and other than
demos we can already say that exciting solutions like ATRIUM that make use of this project are appearing.

For this event we have the chance to have it presented by some ON.Lab team members and developers. They will
introduce attendants to the technology behind ONOS and will propose challenges ranging from
application design to ONOS hacking or modifications.

You have all the information in this web page.

http://ewsdn-hackathon.i2t.ehu.es/

The registration information will be available before July 30th.

how to implement the various tables of openflow in hardware

hello! everyone,i wonder how the various tables of openflow are implemented in hardware switches. for a flow table entry, both the match field and the action are implemented by TCAM? or other kinds of memory is also ok? and the group tables? 
Thanks!

SNAC - EAP-TLS

Hello all,

Hello all,
I would like to post my question in specifically discussion list but it isn't available. I'm working with SDN authentications and would like know if the controler SNAC works with EAP-TLS protocol. I want to implement a PKI for a SDN with auto signed certificates, is it possible with SNAC?

Thanks a lot,

HP SWITCH - installation of flow entries through POX

Hi,
I am using HP-Switch 5400 K 15.17 and I am having issues installing flow entries with pox. I run ./pox forwarding.l2_learning for the installation of flow entries. The version of OpenFlow is v1.0 and the errors that I receive are:

1. OFPFMFC_EPERM
2. OFPBAC_BAD_OUT_PORT

Can anyone help me with it?

Thanks!

packet hit

hi everyone, is there any mechanism in openflow that  after flow entry has been installed, whenever packet that match the entry has the ability to notify/not to notify the controller? (switch to controller message)
thanks.

OVS controller disables ping in both directions .

Hi,
I tried to disable the ping from VM1 to VM2 by adding the below flow

sudo ovs-ofctl add-flow "in_port=<vm1 port>,nw_dst=<vm2 IP>,actions=drop"

However the ping from VM2 to VM1 was also disabled.
According to my understanding the above command should disable ping from VM1 to VM2 but the other way it should work.

Can anyone tell what could be the reason for such functioning?

I am using Opendaylight Helium,Openflow 1.0 and running VMs on top of KVM.The OVS bridge is connected to the controller running on another VM.

Thanks.

SDN & OpenFlow Implementation..!!

Hello All,

I am NEWBIE in SDN & OpenFlow areas. I have Huawei switches (S5700 series) in my company and wish to demonstrate SDN in my company both towards having CapEx & OpEx benefits as I came to know through some papers. I am thinking to perform below tasks to KICK START  -

1. OpenFlow LAN Implementation: An Implementation to control LAN.
2. A standard API for network provisioning (i.e. orchestration) for the data center.

But, NOT sure how to proceed. I need HELP in knowing following things -

1. What has to be done?
2. How should I proceed?

I know my understanding in POOR but willing to discuss here to make it streamlined. I am OK with Python/C++/Erlang coding on Linux (Ubuntu-v14.01).

Thanks..!!

Re: Counter Hit

thanks justin for your confirmation. Actually i have tested on OVS and i can confirm that eventhough the action is set to drop but the flow statistic is still updated to the controller. thanks again

Yes, I believe it should.

OF on Alcatel OmniSwitch 6850E with pox controller

Hello,

I would like to perform a set of experiments on a real network
possibly separating the normal traffic from the OpenFlow
"experimental" traffic.

I have an Alcatel OmniSwitch 6850E that connects a set of PLCs that are
speaking Ethernet/IP. I'm coding my controller in
Python using the pox framework (OpenFlow 1.0 compatible).

I'm simulating my scenario using mininet and cpppo python module to
generate some ENIP traffic (cpppo supports only a subset of ENIP).

Do you have any suggestions on how to enable OpenFlow on my switch?

Thank you !

Dear Colleagues

It's my pleasure to present the Call for --Demos and Posters-- for the fourth edition of the European
Workshop on Software Defined Networks, EWSDN 2015.

The workshop will be held from 30 September to 2 October 2015 in Bilbao, Spain and will be hosted by the
University of the Basque Country in the Bizkaia Aretoa venue.

This CFP can be be downloaded at

http://www.ewsdn.eu/files/Documents/EWSDN2015/ewsdn2015-cfdp.pdf

IMPORTANT DATES – DEMOS & POSTERS
Submission close	15 July 2015
Notification to authors	25 July 2015
Camera ready		30 July 2015

SYNOPSIS AND GOAL
EWSDN has been focusing during the last years in bringing together, in a highly interactive event,
researchers and practitioners at the leading edges of software-based networks, following a rather
practical approach and seeking for being useful to establish links, technical exchanges and
interactions among the community in Europe and beyond. 

CONTRIBUTIONS TO THE WORKSHOP

Demos
Authors from industry and academia are encouraged to present novel prototypes corresponding to relevant
topics of the workshop. This includes the full spectrum from work-in-progress prototypes to
ready-to-us "products". The submission of a two-page concise description of the work is solicited.
Authors are encouraged to provide a pointer to a short video illustrating the running demo. If the
submitted paper is accepted, a live demonstration is to be arranged during the assigned session. Wired
connectivity will be provided for demos.

Posters
Ongoing research activities can be presented as posters. This is an excellent opportunity to initiate
fruitful discussions and to get useful feedback from EWSDN participants. A two-page paper clearly
summarizing the work is solicited. In case of acceptance, an A0 paper size poster is to be prepared and
presented at the workshop, which visually describes the work.

Generally, we are interested in the following topics:
•	Advancements in SDN technology
•	SDN and NFV
•	Interaction with legacy networks
•	Applications and SDN
•	Education and SDN/NFV
•	Experimentation and deployments
•	Industry and SDN

SUBMISSION AND PUBLICATION
Submissions must follow the IEEE Conference Style, A4 format, up to 2 pages, double column, 10pt font.
Please use standard IEEE conference proceedings templates. EWSDN submission will be managed using the
EasyChair submission system. Submissions for Demo & Poster contributions will be peer-reviewed and
submitted for indexing and publication to IEEE Xplore.

Best regards and see you in Bilbao and remember that updated information is always available at http://www.ewsdn.eu

For any information contact ewsdn <at> i2t.ehu.eus
