  1. Infrastructure & Methodology (The cool group)

  2. Problem space • What is “self-management” anyway? • Defined broadly - anything that does not require (or reduces) human interaction after configuration or indication of intention • Insight: service level differs from device level • Consequence: Human intention specified at service level • Translated to device level • Control loop handles issues when intention is not met

  3. Yet more problem space • Two separate infrastructures are required • One that accommodates the new self-management tools and methods (the real system) • One for measurement & evaluation testing (the control plane) • Models (abstractions) for configuration and workload are required for simulation and emulation • The evaluation environment must provide level of detail appropriate to self-management system/method being considered

  4. Requirements • Managed require extended capabilities • Ability to express formal specification of intent • Extended UPNP? • Ability to express capability • Ability to express current status • Put into a model and a basis for control action

  5. Next steps • How do we make progress? • Establish a baseline for self-management • Establish metrics and measurement methods/tools for evaluating self-management • Establish evaluation infrastructures (simulation, emulation, in-situ)

  6. Research opportunities • Network configuration (service level) specification • Optimize performance (sla’s) for minimum cost • Best practices for translating to service policies given device capabilities • Understand device/protocol interactions • Define and collect metrics for improvement • Down time/failures • Volume of help desk complaints • Human involvement • Simplicity(?)

  7. Opportunities continued • Build “Controllers” for self-management components • Define testbeds (simulation, emulation, in situ) • Instrumentation to evaluate and validate • Test cases • Simulation models
