Testbed Federation Survey

To establish the feature set among the existing CONET testbeds as potential candidates for the future CONET Testbed Federation (CTF), we have performed an extensive online survey. The questions cover a range of hardware, software and policy issues that formed the basis for the CTF platform requirements analysis and were used to compile a single point of reference for the existing testbed resources at disposal of CONET partners.
