SDN & Routing Protocols

Hey folks,

Another newbee question: Will the future SDN networks have routing protocols such as OSPF, EIGRP? I apologize if these questions are "simple" but i really cant find this information anywhere.. I know that hybrid will be able to support the old protocols and i know about routeflow. 

What i specifically want to know is: Will future SDN networks need OSPF/EIGRP? Does SDN in its pure form mean the end of OSPF/EIGRP?

Kind Regards,

Merchant Silicon & OpenFlow

Hey folks,

Perhaps a silly question: I am kinda confused because i was thinking that OpenFlow wouldn't be possible without Merchant Silicon. This because the Cisco`s and Brocade`s wouldn't allow the support of OpenFlow on their devices? I mean why would they (especially Cisco) when custom hardware and features is their core business right? Can some one please explain this to me? 

Nick McKeown said that Merchant Silicon was a revolution in itself, at the ONS: https://www.youtube....h?v=W734gLC9-dw 3:05. Lets say Merchant Silicon didn't exist, what kind of an impact would that have on OpenFlow? Would the Cisco`s not support OpenFlow and thus we`d be stuck?

Thanks in advance!

OpenFlow Driver Contest

FYI:

Press Releases

Open Networking Foundation Launches Industry’s First Open-Source "OpenFlow™ Driver" Contest

 

Competition to Encourage Implementation, Interoperability of the OpenFlow Standard

 

OPEN NETWORKING SUMMIT, Santa Clara, Calif., April 17, 2013 – The Open Networking Foundation (ONF), a non-profit organization dedicated to promoting Software-Defined Networking (SDN), today announced the industry’s first competition to create an open-source "OpenFlow™ Driver.” The competition is open to the worldwide development community to create an interoperable open-source implementation of the latest OpenFlow standard. ONF intends the competition to produce an OpenFlow driver that everyone from network equipment vendors and ISVs to operators, and larger open-source projects can use for easy transitions between different implementations of the OpenFlow protocol. The winner of the “OpenFlow Driver” competition will be awarded one grand prize of $50,000.

 

“ONF is committed to solving market needs in very practical ways,” said Dan Pitt, executive director of the Open Networking Foundation. “This competition is designed to encourage additional SDN innovation by seeking additional open-sourced technology solutions. We want this OpenFlow Driver to be of use for global developers of OpenFlow products, making it easier for them to build value around and easily update the OpenFlow protocol component with the latest ONF specifications as they evolve.”

 

The competition is open to all organizations and individuals worldwide interested in developing an OpenFlow driver that any developer can use in a controller or switch to maintain compatibility among switches and controllers. The contest will open for submissions on April 16, 2013 at 12:00 a.m. Pacific Daylight Time, and will close on August 15, 2013 at 11:59 p.m. PDT. Judges, who will be selected by the Foundation, will critique on the following:

 

·         Compliance with the OpenFlow specification standard

·         Correctness of operation with test harness

·         Ease with which the submission can be integrated into a controller

·         Completeness of the implementation

·         Clarity of the code and architecture

·         Memory footprint

·         Potential performance and scaling of the architecture

·         Portability of the code

·         Modularity of the code

·         Extensibility and maintainability of the code

·         Integration with multiple programming languages

·         Performance and scalability of the code

 

The winner will be announced on September 30, 2013. The winning entry will be provided under both Apache 2.0 and GPL dual-licenses for maximum compatibility with both open-source projects and commercial ones. For more information about the open-source “OpenFlow Driver” competition and submission guidelines, please visit www.opennetworking.org/competition.

Pantou on TP-LINK port down status not sent

Hi All, sorry for sending another email however i have a strange thing happening on the WR-1043ND. Basically when disconnecting a client irrispective if by cable or issuing ifconfig eth0 down, the AP doesnt send any port down notifications to the controller. I've checked thorugh wireshark and infact i confirmed that these are not being recieved. Any ideas why this is happening please ?

Re: Fwd: Openflow Switch on TP-LInk

Hi Shabbir ,

Thanks for your reply. Just been testing it right now. managed to make it work, I copied again the config from Pantou wiki and inadvertetly had a small typo which made my datapath failing to start :/ Thanks anyways for your help.

I have just one question if i may - if the client gets disconnected from the AP, the controller is not notified that this happened ( i think this is normal right ? ) Does anyone has an idea how to notify the controller ( i am using floodlight) that clients have leaved the AP ?

Etienne

Hi All,

I just installed the AP in order to become an openflow switch however i'm encountering a slight issue where it is connecting and after a few seconds it is disconnecting again. I'm not sure from where is the problem but i'm suspecting that it is coming from the configuration of openflow ports. Can you help me out please and tell me where is the problem.

Below is the default config when the AP was flashed using OpenWRT , i changed the ip. Connecting through wi-fi and ping the controller is sucessful. As from the AP i can only just see connecting, connection failed and connection dropped after each other.

Now as ofports i think that there is the problem , just afraid of bricking the AP.  ( Just to make it clear the AP is running 1.4 hardware and i think i used an incorrect image).

Fwd: Openflow Switch on TP-LInk


Hi All,

I just installed the AP in order to become an openflow switch however i'm encountering a slight issue where it is connecting and after a few seconds it is disconnecting again. I'm not sure from where is the problem but i'm suspecting that it is coming from the configuration of openflow ports. Can you help me out please and tell me where is the problem.

Below is the default config when the AP was flashed using OpenWRT , i changed the ip. Connecting through wi-fi and ping the controller is sucessful. As from the AP i can only just see connecting, connection failed and connection dropped after each other.

Now as ofports i think that there is the problem , just afraid of bricking the AP.  ( Just to make it clear the AP is running 1.4 hardware and i think i used an incorrect image).


/etc/config/network

Reg: Is it possible to implement Openflow and communicte out of the pc/laptop?

Hello, 

I have implemented the openflow network and I am wondering why I am not able to communicate from a browser running on Chrome, to the outside network. 

Is it because 192.168.56.101 is a host-only network? 

In this case, how to traffic generate using a browser located outside  to a mininet topology host (h3,h4, h5)?

Regarding Mininet: In the tutorial, after installation of qemu-kvm, the :
qemu-system-i386 -m 512 MininetVM.vmdk -net nic,model=virtio -net user,net=192.168.101.0/24,hostfwd=tcp::8022-:22
comand, I am getting an error- unable to find the IP address., ie the command is not working properly. Any suggestions?
