By today, a number of research and industrial efforts are underway to built complete networks, primary for secure key distribution, i.e., so-called Quantum Key Distribution Networks (QKDN). This memo briefly explores the space of QKDNs and identifies spots of potentials interest to develop standardized protocols specific for such networks.}, }
