  1. Semana da Escola de Engenharia da Universidade do Minho Outubro 2011 MiNSC: Network Services Configuration Made Easier Miguel Lopes, António Costa e Bruno Dias {miguellopes,costa,bruno.dias}@di.uminho.pt

  2. Presentation Outline • Integrated Network Management • MiNSC • Evaluation • Prototype • Conclusion

  3. Integrated Network Management • Communication network’s increase • Size, diversity, functionality and complexity • Diversity of management solutions • Protocols, languages, data models • Highly complex network management solutions • Integrated network management solutions • Automation of network management

  4. Integrated Network Management • RFC 3139 Management Translations

  5. Integrated Network Management • RFC 3139 Management Translations • FOCALE’s Autonomic Element & WBEM

  6. Integrated Network Management • RFC 3139 Management Translations • Syntactic Translations – Limitations • Easily automated • Overlapped concepts • Data inconsistencies and collisions • Semantic Translations – Limitations • Complex to implement • Lack of formal semantic description • Administrator dependency • Complex for highly heterogeneous management domains

  7. MiNSC • MiNSC’sNew Management Model • Network Service Configuration Management

  8. MiNSC • Mid-level Network Service Configuration (MiNSC) • Service management information models based on the service’s standard definitions • Two management abstraction layers • High and low management abstraction layers • Active and Candidate nodes classification • Secure, reliable and efficient configuration management (SNMPv3 over TCP) • Overcomes the implementation of management translations

  9. MiNSC • MiNSC’s Two-layer Architecture

  10. Evaluation • Theoretical evaluation • Objectives: • Integrated network management method • Verify the support for larger scale heterogeneous management environments • Evaluated network management frameworks: • Cfengine • WBEM • FOCALE • MiNSC

  11. Evaluation • Heterogeneity • Most frameworks support integrated network management based on management translations • MiNSC provides a different integrated network management supported by normalized solutions to overcome the translation mechanisms • Resilience & Scalability • Most framework depend on centralized entities (single point of failure) • MiNSC Indirect instance’s configurations replications

  12. Evaluation • Interoperability • Implementation of proprietary solutions • Standard management information models & management protocol • SNMP + MIB • Summary

  13. Prototype • DNS Service Deployment • Independent DNS management • Automatic setup of a DNS domain • Specified models • DNS Service management information model • DNS node management information model • DNS Servers modules • Bind9 Linux (A) • Bind9 Windows (B) • Posadis MS Windows (C)

  14. Prototype • DNS ServiceDeployment

  15. Prototype • Results • Conclusions • Low variation with deployment heterogeneity • Quick, secure and automatic DNS service deployment

  16. Conclusion • With MiNSC proposal • Simplifies the heterogeneous network service management • Different integrated management framework • Management interoperability is guaranteed • Overcomes the need for intermediary management translations • Service management automation • Resilience & scalability concerns
