1. Introduction
How Can the Next Generation Network Be Viewed?
Requirements for the network
● Enhancement of network functionality
・ Multimedia information transfer
： IP-based high-speed broadband communication
・ Service quality assurance
： IP-based bandwidth control
・ End-to-end security
： Providing network authentication, etc.
・ Seamless fixed/mobile services
： Providing versatile mobility functionality
● Creation of new services and business models
・ Advanced use of network services： Providing APIs
Next Generation Network (NGN)
NGN will grow as a social infrastructure, by resolving
issues, while taking advantage of the openness of the
Internet (IP network).

1. Introduction
NGN (Next Generation Network) Architecture
■ Standardization in progress at ITU-T
■ Broadband and QoS-controllable IP network
■ Separation of the service stratum (service providing capabilities) from the
transport stratum (information transfer capabilities) to provide diversified
services

•
Approaches to Network Infrastructure
Network Infrastructure needs to be enhanced in terms of
- its Capacity
- Power savings
- Advanced Value-added Functionality
in all layers of Core, Edge and Access.
Core
・Large capacity: High-speed optical transport technology (40G, 100G)
・Power savings: Photonic network (route switching at the
wavelength level)
Edge
・Large capacity: High-speed search technology
・Power savings: Improvements in architectures, circuits, and devices
・Advanced functionality: Service stratum linkage
( QoS control/ security/ APIs )
Access
・Large capacity: GPON (2.4Gbps-FTTH)
・Power savings: Specialized LSI with low-power SerDes
・Advanced functionality: QoS control supporting triple services
(data, voice and video)
