  12. Introduction – Goal of this Meeting • NOBEL only 6 months to go • We need to reach the goals • Reach valuable results • According to contract • Document them properly in deliverables • Implement and provide them for tests and demonstrations in WP8 • Disseminate them in publications and standarization

  13. Report on Board Meeting • Status of the project • Deliverables ok • Publications ok • Standardization contributions needed • Training needed • Demonstrations needed • NOBEL book (mainly WP5&6, driven by Alex Stavdas) • Document exchange with PROTAGON (UK Project) • Closing the project • To be continued tomorrow • Tool reporting monthly reports • Meeting colocated with workshop • Delay in financial audit reports earlier next time

  14. Review of D18 and Task Force Activities • D18 (“Conclusions on NM and CP functional scope and standardization approaches; NM and ASON prototype functional scope”) had some small delay because of change of responsibility (Marconi <-> ACIT) • Overview without going into details

Something else? • Future work - what to do next with them? • New contribution from Abdel • fault localization and correlation for transparent network • Other contributions • E.g. resilience?

  17. Centralized versus distributed path computation TF • D18 contribution to concepts and descriptions of pure (centralized and distributed) solutions of path computation • Future work • New contributions? • Next step should be hybrid solutions • PCE is not regarded as hybrid since it is fully integrated into the CP • However, PCE is an important topic for further work • Currently elaborated under SF TF

  18. Signaling Framework TF • DCN Dimensioning • UNI TF • PCE • Inter-carrier E-NNI • ASON-GMPLS interworking • MPLS-GMPLS interworking and convergence/migration • Planned • Vertical integration and ML TE • GMPLS control of Ethernet networks
