With the development of IP networks and FMC services, requirements for simplified network operation and maintenance (OAM) become higher. Huawei is greatly concerned about how to further simplify network OAM and reduce the OPEX. Based on her deep understanding on customers' OAM mode and comprehensive study on the future development of networks, Huawei first launches the next generation network management system, that is, the iManager U2000 system (U2000). The U2000 is an integrated and unified management platform for all the network equipment provided by Huawei. It inherits the functions and operation modes of the T2000, N2000 BMS, and N2000 DMS, and can manage transport equipment, access equipment, and IP equipment (including switches and PTN equipment) in a unified manner. With powerful management functions at the element management layer (EML) and network management layer (NML), the U2000 is designed as the network management system for Huawei equipment.
