  2. Outline • Introduction • The Cognitive Framework • Performance Evaluation • Conclusion

  3. Motivation • Advancements in network technologies dramatically increased management complexity • Degradation of performance due to time-varying network conditions is a challenging issue. • It is not always possible to anticipate the best setup due to the unpredictable state of the network.

  4. Goal • A novel approach to dynamic reconfiguration of network protocols • Cognitive networking • Cross-layer design • Distributed decision-making

  5. The Proposed Solution • CogProt: cognitive framework for dynamic adjustment of communication protocols • Support initial setup and runtime reconfiguration • Decentralized • Incremental deployment • Low processing requirements • TCP/IP compliant

  6. CogProt Overview

  7. The Cognitive Loop

  8. Performance Evaluation • Ns-2 simulations • Parameter of interest: increase factor of the TCP congestion window

  9. Average Throughput

  10. Throughput over Time

  11. Conclusion • We have proposed a distributed cognitive framework to deal with management complexity and avoid performance degradation • No changes on standard protocol messages or operation. • Incremental deployment • Wide range of tunable parameters

  12. Future Work • Evaluation of other probability distributions • Application to other TCP/IP protocols • Real implementation • Further development of CIS architecture and signaling
