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

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

Controller forwarding a Packet-out for a Packet-in

Hello everyone,

So we have an OpenFlow enabled virtual switch running on Linux.

I'm running HP SDN controller. The 1.3 connection b/w controller and switch is established and the initial communication is done (Hello request/reply, Multipart request/reply for Switch Desc, Port Desc & Table Desc.). And the subsequent Echo request/reply is going on.

I've created 2 TAP ports on Linux which are part of OpenFlow and those 2 ports are acknowledged by the controller as well, as evident from Port Desc reply and also HP SDN GUI.

You can treat our virtual switch to be similar to OVS and an additional data plan module running underneath it where we program Flow Entries.
I'm sending a ping packet from tap0 --> tap1 using 'netwox' traffic generator. The ping packet is written on tap0 and our data plane module passes the packet on to our virtual switch 

We have no flows installed and the default table miss entry in data plane says "output to controller". So the data plane sends the ping packet to Control plane which encapsulates it within a Packet-in and fill in appropriate details - 

packet-in Match - 
i. Source MAC.
ii. Dest MAC.
iii. in_port.

The packet-in goes to controller as verified in wireshark logs. Now, correct my understanding and please forgive if I'm wrong - I'm expecting a packet-out corresponding to the packet-in.
But the packet-out is NOT egressed by the controller. I hoped at least the controller let out a packet-out with action FLOOD, if it has not learnt the MACs already.

As for the ping request, I've filled in the MAC header's Source/Dest MAC with tap0 as Source MAC and tap1 as Destination MAC.
And the IP source/dest to be the IP configured on tap0/tap1 respectively.

This activity has been repeated with ODL controller as well, but no packet-out is let out for a packet-in.

My question is:
1)  Is there some pre-requisite of the controller which if not fullfilled, the forwarder behavior of controller doesn't work.

Please let me know if more info is needed, I shall provide the same.

Thank you,
Vishal

question about iperf

Hi friends..
want your help plz

i have been connected 2 vms through openvswitch and used iperf (tcp test ) to measure the throughput but when using (udp test) to measure the jitter i got problem ( i have to specify the number of bytes in the test) 
- the warring msg (did not receive ack of last datagram after 10 tries) 
-i used this command 
iperf -c 10.0.2.17 -u -t 60 -n 64

thanks

FlowVisor Stop when OVS is connected to it

Hello,


I have 2 virtual machines (ubuntu using virtualbox). 

In the firt I installed OpenvSwitch and in the second I installed FlowVisor (I followed this link:  https://github.com/OPENNETWORKINGLAB/flowvisor/wiki/Installation-from-Binary ) .


I run Flowvisor using this command: $ sudo -u flowvisor flowvisor​. But when I connect the switch to the FlowVisor (using set-controller), I get in FlowVisor: startup failed : null.


How can I fix this problem? 


Thank you so much​.

output port equal input port behavior

Hi All,

I just make a quick testing via mininet, I dump the flow as followings:

output port equal input port and mod_vlan action, however it does not take effect, the vlan does not been modified:

cookie=0x8, duration=2422.356s, table=0, n_packets=0, n_bytes=0, idle_age=8, hard_age=1367, priority=1002,in_port=1,dl_vlan=2 actions=mod_vlan_vid:3, output:1


while I use the IN_PORT keyword:

cookie=0x8, duration=242.36s, table=0, n_packets=7, n_bytes=105, idle_age=8, hard_age=1367, priority=1002,in_port=1,dl_vlan=2 actions=mod_vlan_vid:3, IN_PORT


It works, so I would like to know the design consideration and behavior.

Thanks,

Derek

set_field action verification

Hello,

I am trying to modify a header field by using set_action instruction. I have been able to successfully add a flow table entry corresponding to this. But how can I actually verify if the change has taken place successfully in the packet.

I have tried doing this:

sudo dpctl unix:/tmp/s1 flow-mod cmd=add,table=0 in_port=1,eth_dst=00:00:00:00:00:02 apply:output=2,set_field=eth_type=0x8848

The flow table entry has been successfully inserted. But how to make sure that the change has been successfully applied?

Any help is appreciated. Thank you
