3. 3 Slice Creation: CEDL Canonical 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

6. 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 METHODOLOGY & GUIDANCE EXPERIMENT AUTOMATION TOPOLOGY TRAFFIC ATTACK DATA-CAPTURE ?
