Splitting of HNCP-02 to a generic transport-independent protocol (DNCP-00) and the Homenet-specific application of it (HNCP-03) seemed desirable based on input from IETF91 in Hawaii.

Therefore, we did the split, clarifying and reworking the few nits we had with the original HNCP-02. In general DNCP is a protocol-framework which defines how nodes communicate, how data is encoded and secured (earlier security considerations which were temporarily split into a separate draft have been remerged) in an abstract way. Details (such as transport, timer values, port numbers, etc.) are left to the individual DNCP profiles such as HNCP.

As the state synchronization mechanism may be also of use here, crossposted :-)
