NGN Main Principles
NGNs are structured, and are separated into functional planes, that include:
• Access• Transport & switching• Control & intelligence• and service (application)
Layers are independent - they can be modified or upgraded regardless of other functional layers

NGN Management Principle: – "future-proof" architectures
supportive of distributed management and independent of any particular communications technology
– protocol-neutral information models supportive of an interoperable, multi-protocol environment
– use of concepts and implementation technologies strongly supported by the IT and computer industries
