It would be better to go for latest version as suggested by Tony. We might want to look into the following resolutions just in case https://issues.jboss.org/issues/?jql=project%20%3D%20NETTY%20AND%20fixVersion%20%3D%20%224.0.0.x%22%20AND%20status%20%3D%20Resolved%20ORDER%20BY%20priority%20DESC

Earlier, for protocol-plugin and codec  I had used 3.2.6 because of the stability, drastically different 4.0x API , wider mindshare of experience in forums on 3.2.6 and documentation.
If we account and contain Netty dependencies to limited classes, changing to newer version would not be an issue.

I would suggest using Netty 4.0.9-Final
Still in distribution you could overrride minor number.

We may want to settle onto a single version of netty throughout ODL… here's what I see so far:

The netty pipeline layout (after the version negotiation) is now a part of the OpenFlow library. They have the rough idea of the interactions with the plugin at https://wiki.opendaylight.org/view/Openflow_Protocol_Library:Main and the architecture at https://wiki.opendaylight.org/images/0/02/Openflow_Protocol_Library.pdf. I will let Tony Tkacik or Michael Rehak/Michal Polkorab answer the question with respect to the details on how the pipeline is done in the OpenFlow library.

Hi Abhijit,


I think I was not quiet clear

My question was primarily if we had nailed-down how this would be realized in Netty context - as Chris mentions, that cannot be overlooked as only a programming detail
because pipeline layout and their variances thereof  is the basic implementation aspect of plugin

The negotiation will be actually handled in the plugin - however once the negotiation is done, the version detection & switching to either the OF 1.0 or 1.3 codec will be handled in the OF library.

Adding the library dev to the thread.
The negotiation decisions are policy driven through the plugin (connection mgr (where applicable) –> plugin –> library), but the negotiation machinery and Netty aspects are library implemented.  These are good questions to come to complete clarity and agreement on!

Re: [controller-dev] OF Plugin Design Updated.


Hi Prasanna,

Had a few clarifications

1. Are we going with Netty 4.0x for the implementation ?
2. Do we change the Netty Channel pipeline once version-negotiation is completed ?
 More like following

    When 1.0 OF Header version is encountered (no need for version-negotiation)
            - Pipeline would only contain :  
"ofmessage1_0decoder", "ofmessage1_0encoder", "idle", "handler"

    When 1.3 OF Header version is encountered

            -
Pipeline would only contain :  "ofmessage1_3decoder", "ofmessage1_3encoder", "idle", "handler"

    When 1.3 OF Header version is encountered and 1.0 is negotiated - Assuming that this case to be supported for sake of completion

            -
Pipeline would only contain :  "ofmessage1_0decoder", "ofmessage1_0encoder", "idle", "handler"

    When 1.3 OF Header version is encountered and 1.3 is negotiated - MOST LIKELY case

            -
Pipeline would only contain :  "ofmessage1_3decoder", "ofmessage1_3encoder", "idle", "handler"                

And in order to accomplish "When 1.0/1.3 is negotiated" action, we would have a "
version-detector" in all above pipeline configurations which uses only the header-version?
