What is NGN
Next Generation Network (NGN) is a service-oriented network.Through the separation of service and call control, as well as call control and bearer, the service-independent architecture is implemented, which makes services independent of network.
NGN is a kind of open and integrated network architecture. NGN is a kind of brand-new network integrating voice, data, fax, and video services.3

Summary
NGN is divided into four layers: access layer, transport layer, control layer and service layer.
NGN is the four-layer hierarchical network based on packet switching and transmission. Interworking between different layers is realized via open standard protocols, which provides NGN with
considerable advantages and flexibility.
Located at the control layer of NGN, SoftX3000 is the core control equipment in NGN for information interchange. It is used to control the communication of various MGWs.
The transmission and interchange of information streams between MGWs do not fall into the control of SoftX3000. It is under the control of transport layer instead.30
