# measurement-framework
Part of ARCFIRE 2020, WP3 work package.
+
+Workflow, both external and internal:
+
+ (1) user defines the network graph, creating instances of model.Node
+ and model.DIF classes
+
+ (2) user creates an instance of a Testbed class
+
+ (3) user creates an instance of prototype.Experiment class, passing
+ the testbed instance and a list of Node instances
+ - at the endo of the base Experiment constructor, the
+ generate function is called to generate information about
+ per-node IPCPs, registrations and enrollment, ready to be
+ used by the plugins
+
+ (4) user calls run() on the prototype.Experiment instance:
+ - First, run() calls Experiment.swap_in(), which
+ in turns calls Testbed.create_experiment(), passing the
+ nodes and links (?)
+ TODO: fix this interface: what should swap_in(), and
+ so create_experiment() return exactly? Current interface
+ seems broken
+
+ - Second, run() calls a prototype-specific setup function,
+ to create the required IPCPs, perform registrations,
+ enrollments, etc.
+
+ - Third, perform tests (TODO)
