9 years ago Hi Yunmei,
yes, it is possible and should be straightforward as you guess. It is in our roadmap to include support for NDNx in addition to CCNx but until Q1 of 2015 we wont be able to fully commit to this task. We welcome any contribution on that front!
Let us know how it goes and if you need any help.
Cheers, Christian

9 years ago Hi Christian, I switch my experiments platform from CCNx/NDNx to NFD/ndn-cxx, do you have any schedule to support NFD/ndn-cxx for mini-ccnx?

9 years ago According to our estimates we shall have something working for NFD during January 2015.

9 years ago Hi everyone, Just to give a heads-up, this week Christian and I will start working on updating the GUI of the configuration file generator (mn-ccnx edit) and as soon as we finish, we'll start working on migrating mn-ccnx to support the NDN platform (something around the following week). Please let us know if you have done any work in that regard by them!
Caio.

9 years ago Thanks for the update Caio. I will also create a mailing list since it would be more convenient to sync this type of information among the growing number of users and interested parties in evolving mini-ccnx.
Cheers, Christian

9 years ago Hi Christian,
I am trying to modify the code to support NDNx and I met a problem.
What I did: I modified the file mn-ccnx/mininet/node.py and rebuild. I replaced all the "ccn" and "CCN" with "ndn" and "NDN". I installled ndnping, started ndnd, wrote a miniccnx.conf file, and then ran command "sudo miniccnx".
What happened: The command "sudo miniccnx" only worked for the first time. The hosts could ndnping each other, proving that NDNx worked fine in the virtual hosts. If I typed in "exit" and exited mn-ccnx, then the next time "sudo miniccnx" would stop at the position of "*\ Adding hosts:". If I typed in control+c, I would see a list of tracebak and original exceptions.
I don't understand why it could run at the first time but could not run again, unless I reboot ubuntu. I guess there are some resources that are still possessed by the first time process.
Would you please help me with this problem? What are the possible reasons?
Thanks for your time.

I paste the traceback and original exceptions information here:
^CTraceback (most recent call last):
File "/usr/local/bin/miniccnx", line 5, in
Original exception was:

I could find the code " self.cmd("export NDND_DEBUG=6")" in mininet/node.py, the next lines are self.cmd("export NDND_DEBUG=6") self.cmd("export NDND_LOG=./log.{0}".format(self.name))

self.cmd("export NDND_CAP={0}".format(self.params['cache']))

9 years ago here is a pointer to the related efforts to support NDNx: http://redmine.named-data.net/projects/mini-ndn
We will also point to the related tools and github report in the Mini-CCNx wiki

I plan to use NDNx instead of CCNx. I guess Mini-CCNx calls commands like "export" "ccndstart" "ccndc" and so on, then I need to replace these CCNx-related commands with respective NDNx commands. Is that correct? Is it possible that I modify the code so as to use NDNx instead of CCNx?
Thanks for your time!
