- The Protected Core Segment Operational Picture (PCSOP) represents the current view of the Protected Core (Pcore) in an NMCD. It consists of multiple different sources of information, fused together to form a complete picture of the network. To construct the federated PCSOP, an NMCD collects information from two categories. Local information is gathered from various sources inside the Protected Core Segment (PCS) and/or Coloured Cloud (CC). Conversely, remote information is sourced from other entities in the NMCD federation using the information exchange mechanisms described in this document.
