  3. Slice Creation: CEDLCanonical Experiment Description Language • Standard low-level experiment representation – “assembly code” • Output of all tools / input to Federator • Form of / alternative to Rspecs for experiment-wide specification • Expressiveness (today): • Core semantics: • Logical {nodes, links, elements} • Topology (ns2/Emulab) • Annotations: logical attributes (eg, node type) • Type information: router, switch, etc. • Physical selection: map to specific instance • Annotations: physical attributes • “Escapes” to allow physical configuration of hardware

  4. TIED Physical Infrastructure 6/09

  5. Experiment Methodology and The SEER Toolkit • Experimenters select from a palette of predefined elements: topology, traffic, instrumentation, etc. Skeleton palettes for original and customized experiments are available. • Methodology Engine frames standard, systematic questions that guide an experimenter in selecting and combining the right elements • Experiment Automation increases repeatability and efficiency by managing the experiment • Other work • Validating invariants and environment • Understanding and constraining risky behavior PALETTES TOPOLOGY TRAFFIC ATTACK DATA-CAPTURE METHODOLOGY & GUIDANCE ? EXPERIMENT AUTOMATION
