[Planetlab-devel] questions abouting running an independent myplc

Tue May 20 16:20:19 EDT 2008

Hello Keon and all,
here at Univ. of Napoli, in the context of the European OneLab  
research project,
we managed to support (at least in a primitive way) UMTS/HSDPA PCMCIA cards
in a PlanetLab-derived deployment.
Access to these nodes is not open so far, but the pieces of software
needed for this purpose have been integrated in the OneLab codebase,
thans to the support of Thierry Parmentelat.
The biggest problem we found are:
- one conceptual: how to share the card among experiments;
- one practical: how to run commands that need root privileges.
While the second problem has been solved with the use of vsys
the second problem was solved in a first-come-first-served approach.
More complex time-dependent policies have been investigated but not  
implemented so far.
You may find more info in the following two public deliverables
D4B.1 and D4B.2 available on the www.one-lab.org web site
in the "Public Deliverables" section.
In case you desired more info on this, please do not hesitate to
contact either me or Alessio and Giovanni.
Best regards
Roberto
