Dear Cheng, The overall proposal in this I-D is an enlarged version of a typical closed-cycle autonomic network management architecture. It has been enlarged by instantiating a simulator together with the model building and other elements of the analysis stage and knowledge base. Moreover, it has increased requirements for input data, so that both models and simulators have a more realistic view of the network. Because of this I find the document lacks a mapping of the reference architecture and the typical network management architecture, both abstract, in terms of, for instance, MAPE loop, as well as an implementation, as Open Source MANO. > Thanks and Best Regards, > Cheng Zhou (on behalf of co-authors) Regards, Pedro -- Pedro Martinez-Julia Network Architecture Laboratory, Network Research Institute National Institute of Information and Communications Technology (NICT) 4-2-1, Nukui-Kitamachi, Koganei, Tokyo 184-8795, Japan Email: pedro@nict.go.jp --------------------------------------------------------- *** Entia non sunt multiplicanda praeter necessitatem ***
