| | 42 | ==== DETER Abstractions and the Existing Codebase ==== |
| | 43 | |
| | 44 | The DETER research agenda drives the new abstractions, and it differs somewhat from the abstractions that drive the Emulab-derived code base. DETER is interested in sharing experiment infrastructure - including conducting experiments where multiple parties manipulate the environment based on different views of the world and different goals (multi-party experiments). Also, DETER is interested in multi-fidelity, large-scale experiments where the representation of the various partes of the experiment is guided by the researcher's design of the experiment. Finally, we think of experiments as having aspects that go well beyond the definition of the topology or layout, and the abstractions need to support this. |
| | 45 | |
| | 46 | The Emulab code is based on simpler topology and experimentation models, and while its developers have been able to extend it to do more, our changes take the abstractions far enough that relegating the Emulab code to allocating local resources seems the cleanest way forward. Functions including user and project management will move into the SPI, though subsets of that function (basically current Emulab functionality) will remain available through the legacy interface. |
