LayerProtocol Refactoring & Spec pattern

  • Merging of LayerProtocol attributes into NEP, CEP, CSEP & SIP
  • Constraining of Layer multiplicity to 1 for NEP, CEP, CSEP
  • Spec pattern usage & Spec Constraints
Rod LU
  • Agreed to merge LayerProtocol attributes into NEP/CEP/CSEP/SIP - this results in elimination of LayerProtocol class in TAPI
  • Agreed to Constrain Layer multiplicity to 1 for NEP, CEP
  • Agreed that introducing constraints that limits the application of <Specify> (augment) relationship is good practice
  • Rod Lu: CSEP should be multi-layer to allow for specifying/configuring lower (transport/tunnel/internal) layer adaptation properties while creating a upper layer connectivity. Example to be provided in next TAPI call
