Outline
Outline

  • Introduction

  • The Cognitive Framework

  • Performance Evaluation

  • Conclusion


Motivation
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.


Cogprot a framework for cognitive configuration and optimization of communication protocols
Goal

  • A novel approach to dynamic reconfiguration of network protocols

    • Cognitive networking

    • Cross-layer design

    • Distributed decision-making


The proposed solution
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




Performance evaluation
Performance Evaluation

  • Ns-2 simulations

  • Parameter of interest: increase factor of the TCP congestion window




Conclusion
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


Future work
Future Work

  • Evaluation of other probability distributions

  • Application to other TCP/IP protocols

  • Real implementation

  • Further development of CIS architecture and signaling
