A broadband optical access system with increased service capability using dynamic bandwidth assignment Amendment 1: New Annex A – Performance monitoring parameters
Dynamic Bandwidth Assignment (DBA) efficiently allocates resources for variable bit rate traffic transfer over Broadband Passive Optical Networks (B-PON). The requirements and detailed specifications in its core functions have been finalized in the main part of ITU-T Rec. G.983.4. This annex provides extended functionalities of DBA focusing on performance monitoring. It specifies requirements and specifications for these functions. These specifications are implemented in the OLT, and do not have interactions with the ONT. However, since this function has affinity with DBA itself, it is positioned as a normative part of ITU-T Rec. G.983.4 as Annex A.
