What is NGN?
Multi-service network Separated planes Open interfaces A packet mode technology Guaranteed QoS s generalized mobility
Why NGN? Fusion of services and markets Common network IP in back bone
Split of different layers Services
NGN architecture
Network partitioning with respect to IMS
IMS Functional Entities
NGN Signaling protocols SIGTRAN
between PSTN/PLMN and IP networks
H.248
between Media Gateway and Media Gateway Controller
SIP,SIP-T/SIP-I
between two IP networks
H.323/SIP-T/SIP-I For international Connectivity RTP/RT
For delivery of content (voice/data/video etc.)
NGN Protocols

Quality of Service Latency - IPTD Jitter - IPDV Packet Error - IPER
Packet Loss - IPLR Toll Quality Call Completion Rate - TCBH
Availability of Network
NGN Challenges Standardization Laws in each country need to be suitably amended Cost issues
Developing countries are not yet well versed with the
advancements
NGN Future Low cost devices Multi party conferencing Education
Opens up tremendous opportunity
