The disclosure relates to a method and system for virtualized network entity (VNE) based network operations and support system (NOSS). The fundamental entity of network operations is VNE. Each VNE provides the necessary computing, storage, and networking features/functions that are desired by the applications (apps) or services. The apps and services provide initial, normal/nominal and overload scenario(s) based VNE configuration request to the NOSS, and the NOSS offers one or more VNE based apps/services support configuration that can be activated flexibly based on the dynamic demands. The requirements and sample operations of the NOSS, for example, attachment of virtualized layer-3 network entities to NOSS via open and interoperable interfaces, are described.
