** Simple management vs. Distributed node ownership
- manage devices belonging to diverse owners?
** Features vs. Lightweight, low cost
- support devices ranging from PCs to embedded boards?
** Heterogeneity vs. Compatibility
- work with devices which allow little customization?
- support diverse connectivity and link technologies (wireless, wired, fiber)?
** Familiarity & flexibility vs. System stability
- Researchers prefer a familiar Linux env with root access.
- isolate experiments that share the same node?
- keep nodes stable to avoid in-place maintenance? Accessing node locations
................................................................................
- allow interaction at the lowest possible layer of the CN while not
disrupting or overusing it?
** Traffic collection vs. Privacy of CN users
- allow experiments performing traffic collection and characterization?
- avoid researchers spying on users' data?
** Link instability vs. Management robustness
- deal with frequent network outages in the CN when managing nodes?
** Reachability vs. IP address provisioning
- We have IPv4 scarcity and incompatibility between CNs, lack of IPv6 support.
- support testbed spanning different CNs?
* Community-Lab testbed architecture
