  3. 3. <ul><li>Major Trends </li></ul><ul><li>Technology Environment: Multitude of networked/distributed applications </li></ul><ul><li>Social-Economic Environment: Awareness of demographic change in an aging society (Europe and others) </li></ul><ul><li>“ Information” centric rather than “bit” centric at the network level </li></ul>
  4. 4. <ul><li>Integrated support of mobility </li></ul><ul><ul><li>Communication everywhere </li></ul></ul><ul><ul><li>New services – new devices – new interactions </li></ul></ul><ul><li>Complexity is largely due to heterogeneous traffic types (e.g. Data, VoIP, VoD) </li></ul><ul><li>Traditional management has automation but it is still manually planned and deployed </li></ul><ul><ul><li>leads to high cost and error prone </li></ul></ul>2 nd Workshop on IMS enabled Converged Networks New paradigms for services delivery, Paris, Sept 12, 2008
  5. 5. <ul><li>Can In-network management, be the essence for a system to self-govern its behaviour within the constraints of the business goals the system as a whole seeks to achieve? </li></ul>
  6. 6. <ul><li>The TSSG is carrying out research on the Management of Communication Networks and Services </li></ul><ul><li>We are addressing </li></ul><ul><ul><li>Architecture and Methodology </li></ul></ul><ul><ul><li>Modelling and Knowledge Engineering </li></ul></ul><ul><ul><li>Policy Analysis and Deployment </li></ul></ul><ul><ul><li>Algorithms and Processes </li></ul></ul>
  7. 7. <ul><li>In an communication architecture, the basic management element is a Control Loop. </li></ul><ul><li>This acts as manager of the resource through monitoring, analysis, and actions taken on a set of predefined system policies. </li></ul>
  8. 8. IBM: MAPE, 2004 <ul><li>The four functions consume and generate knowledge . The knowledge base can be seeded with known information about the system, and can grow as the autonomic manager learns more about the characteristics of the managed resources. </li></ul>
  9. 9. Motorola: FOCALE, 2005 <ul><li>FOCALE: Foundation, Observe, Compare, Act, Learn, rEason </li></ul>Define New Device Configuration(s) Autonomic Manager Ontological Comparison Reasoning and Learning Managed Resource Analyze Data and Events Determine Actual State YES NO DEN-ng Models and Ontologies Model-Based Translation Match?

  17. 17. <ul><li>Respiration energy used for path ratio refinement </li></ul><ul><li>Glucose is broken down to create energy through two types of respiration (Aerobic and Anaerobic) </li></ul><ul><li>Aerobic respiration creates high energy, and compared to streaming traffic into allocated space </li></ul><ul><li>Anaerobic respiration creates low energy, and compared to streaming traffic into space allocated for different type of traffic </li></ul>Multimedia Glycogen P1 P2 Demand profile paths Data Glycogen Fat F1 Energy
