This standard specifies protocols between the overlay management (OM) functional entity (FE) and all other NGSON functional entities@ and/or NGSON nodes to enable the OM FE involved self-organizing management capability. This capability includes activation and deactivation of an NGSON node and addition@ deletion@ movement@ and copy of an NGSON function entity from or to an NGSON node. This standard also specifies protocols among service routing (SR) FEs to enable OM FE non-involved self-organizing management capability@ such as re-organization of overlay structure among multiple SR FEs for recovery from a failed or overloaded SR FE or for performance improvement of service routing. Purpose The purpose of this standard is to enable NGSON network operators to reduce OPEX of NGSON networks based on self-organizing management capabilities of NGSON including self-configuration@ self-recovery@ and self-optimization of NGSON nodes and functional entities.
