Methods, systems, and computer program products for a hierarchical, redundant OAM&P architecture for use in an IP multimedia subsystem (IMS) are disclosed. According to one aspect, the subject matter described herein includes a system for managing an Internet protocol multimedia system (IMS) network. The system includes a network operations, administration, maintenance, and provisioning (OAM&P) entity for communicating with an operator's network, a system OAM&P entity associated with the network OAM&P entity, and at least one message processing entity associated with the system OAM&P entity for processing signaling information and for implementing at least one application. The system OAM&P entity receives OAM&P information from one or more message processing entities and communicates at least some of the received OAM&P information to the network OAM&P entity. The network OAM&P entity receives OAM&P information from the system OAM&P entity and communicates at least some of the received OAM&P information to the operator's network.
