Reusable code & DTLS implementation/support

Mahesh Govind
Dear Experts, I was trying to implement capwap . If Openflowjava have DTLS support , i thought we could reuse it .Could you please let me know whether we have DTLS support for openflow java . Mahesh

No - DTLS is not supported. There were no virtual OpenFlow switches which supported OpenFlow over UDP.

Thanks for the info.Do you have some insights regarding the best Dtls libs which we could use. On 31 Oct 2014 09:19, "Abhijit Kumbhare" <abhijitkoss@...> wrote:

Not really - perhaps Michal P has an idea.

Mahesh, Not sure of any libraries in java.
But in C we have http://yassl.com/yaSSL/Products-cyassl.html and openssl(openvpn may use be the reference application).
May be using JNI we could achieve DTLS.

Hi Mahesh,
openflowjava doesn't support DTLS at the moment. However, we have found a library called "Bouncy Castle" which supports DTLS. This library is already present in controller. So we intend to analyze pros and cons of this library - and afterwards we might implement it to enable DTLS. NOTE: There are currently no virtual switches supporting communication over UDP to controller - so DTLS support is now a low priority item. UDP also needs to be tested / optimized more.

HI Michal, Thanks a lot for the info . COuld you please let me know which module of the controller is using Bouncy Castle . I hope i could reuse most of the stuff and add a parser and state-machine to start with . regards Mahesh

I haven't checked source codes yet, but i tried to run "mvn dependency:tree -Dincludes=org.bouncycastle | less" and then looked for "org.bouncycastle".
Bouncy castle dependency has been found in several projects (some dependencies might be transitive) like: topologymanager.shell netconf-testtool hosttracker.shell netconf-ssh ...
I would try and see the netconf-ssh project to get more information.
