tc.), multivendor (common information and interface standards defined), and multido- main (enterprise, telecom, etc.) kind of environment, bringing in the concept of a unified solution that meets all requirements. 17.2 NGNM Basics Multiple standardizing bodies are coming up with standards for NGNM. The intent of TMF with the release of TR133 was to come up with details of the prog- ress SO far by other bodies, how liaison can be formed between bodies working on developing standards in the same space, and how to realize business benefits by bringing up standards for NGNM. The holistic view of telecom space is achieved in TR133 by splitting the NGNM space across business, system/architecture, imple- mentation, and deployment. It is in line with the TMF (TeleManagement Forum) concept of NGOSS (Next Generation Operation Systems and Software), which demarcates the service provider space from service developer space and technology specific implementation from a technology neutral implementation. NGNM originates from the need for managing the next generation network (NGN). NGN according to ITU-T standards is a packet-based network that can support a wide variety of services. Some of the key buzzwords around NGN are its ability to offer services anytime and anywhere. It is multiservice, multipro- tocol, and multiaccess-based network. NGN also fosters a multitechnology and Next Generation Network Management (NGNM) multivendor environment. Most of all it provides a secure and reliable communi- cation channel. Now let us explore these terminologies in more details. Anytime and anywhere means that it is not tied to a specific kind of network or equipment to access the services offered on NGN. The services are always on and moving, change in underlying infrastructure or access technology does not affect the cus- tomer in terms of accessing the service. Multiservice means that multiple services can be hosted on the network, multiaccess means that the access layer can be fixed, mobile terminals, or any other kind of access tech
