[nox-dev] meta.xml converts to meta.json
hello,everyone. I am a new comer of openflow, now i want to use the mobilevms app, but my branch of NOX is destiny, i need to convert the meta.xml to meta.json, because the old version of NOX uses meta.xml to describe the compenents, but the NOX destiny uses meta.json to describe the compenents. i also konw that the nox-convert-meta.py script(in src/scripts) is meant for doing this, but i do not konw how to use it , anyone who can help me,thank you very much. It is better to show the output of the meta.json for mobilevms.The attachment is meta.xml file for mobilevms.

Re: [nox-dev] Error building dev/destiny-fast branch
This branch is quite a bit behind the actual development. We're preparing to release the updated codebase in the near future. But for one thing, Python doesn't work in it. So you probably need to do --with-python=no when you run configure. Hope that helps. -- Murphy On Oct 25, 2011, at 8:49 PM, Andreas Voellmy wrote: Thanks.

Re: [nox-dev] meta.xml converts to meta.json
To use it, you just do something like:
python nox-convert-meta.py meta.xml meta.json
But here's the result:
{
components: [
{
python: nox.netapps.mobilevms.mobilevms,
dependencies: [
python,
pyrouting,
pyauthenticator
],
name: mobilevms
},
{
python: nox.netapps.mobilevms.basicrouting,
dependencies: [
pyrouting,
authenticator,
broadcast_resolve
],
name: basicrouting
}
]
}
Just paste that into a meta.json file and hopefully you're good to go.

Re: [nox-dev] Error building dev/destiny-fast branch
I only updated the 'switch' app in that code base, and I never looked at 'hub'. My guess is that the hub app is doing so little that locking within boost::asio scheduler outweights the actual work done by the hub app. We need to make sure that the amount of work done by each thread upon its invocation is significantly more than the locking overhead in boost::asio's internal job queue. If that is the case, since we are working on a new release, it doesn't make much sense to fix it in that code base. Could you wait for that? Cheers, Amin P.S.: Btw, passing '--enable-ndebug' to configure should boost the performace. On Wed, Oct 26, 2011 at 2:08 PM, Andreas Voellmy andreas.voel...@gmail.com wrote: Thanks.

I'm unclear about how components in the destiny branch work. Do the handlers run concurrently by default, or is there something extra that one has to write to get them to execute concurrently? If something extra is needed, what is it in switch.cc that makes it execute concurrently? Or are you saying that the event handlers in 'hub' are indeed running concurrently, but they aren't doing enough work to get much performance gain?
