The Home ICT platform provides essential functions for Information and CommunicationTechnology (ICT) services in the home that are adapted to service development and servicemanagement. It lets service providers develop Home ICT services rapidly and cost effectively.For this platform architecture, alliances with service providers and device makers areessential inorder toextend the platform’svalue, sowe arealso promoting such alliances.
■ Unified control and management for devices in the home from a home gateway■ Essential functions for development and management of Home ICT services (Communication
libraries/interfacetodevicesin the home, device detection/management, etc.)■ Flexible and dynamic software management using internationally standardized OSGi
technology for Home ICT services
Overview

To curb rapidly expanding medical costs, institutions have to not only raise businessefficiency and implement preventive care; they have to provide appropriate high-qualitymedical services.Our network-based platform enables personal health and medical care data to be sharedamong healthcare providers. The platform also enables healthcare guidance to be providedtopatients at a remote location.
■ Integrates systems with different interfaces■ Uses Single Sign On (SSO) for easy access to information■ Access control in accordance with a privacy policy■ Data structure conforming to HL7 (a medical information standard protocol) and
Continua (a healthcare data standard protocol)■ Safe remote healthcare guidance using video phones

NTT is undertaking research and development of cloud computing technologies known asCBoC (Common IT Bases over Cloud computing) to achieve safe, secure and eco-friendlyclouds required by e-government and core business systems. One of the advantages ofCBoC is the operation and management of virtual resources, which reinforces the benefit ofvirtualization, such as scale-out and efficient hardware utilization. CBoC can be applied tothe development environments of system integrators, infrastructures of SaaS (Software as aService) providers, and server consolidations in enterprises to reduce operating and facilitycosts.
■ Reduces operational workload by en-bloc control of multiple virtual resourcescomposing the system
■ Uses hardware efficiently by on-demand allocation of computing resources■ Reduces the time needed to build a system by using ready-made shared resources
such as shared load balancers■ Reduces the time needed to build a system by using templates of frequently used
system configurations■ Reduces the workload of, and prevents failure in, the application of software patches,
by using templates
Overview
Features
Application scenarios
■ Development environments of enterprises that develop information and communicationstechnology (ICT) systems or services: efficient use of hardware and avoidance ofexcessiveinvestment byon-demand allocation of computing resources
■ SaaS providers’ infrastructures: cost-effective service provision based on low facility andoperating costs byefficient and automatic accommodation of manycustomers
■ Server consolidations in enterprises: reduction in the number of servers, leading toreductions in facilitycosts, facilityspace, and powerconsumption

A VPN*1 authentication system for next-generation networks (NGNs), called “AAA*2,” ―forproviding RADIUS*3 user authentication (i.e., terminal authentication) in response to multipleVPNs on an NGN― was developed. By providing (1) high-level conformity needed for NGN-VPN services, i.e., interoperability (assumed to be with various corresponding legacy-network termination equipment) and handling of line-identification information of legacynetworks/NGNs, (2) high extensibility for flexibly handling future service expansion and (3)service continuity during hardware faults and occurrence of disasters, redundancy ofequipment and facilities between distant regions canbe created at low cost.
■ Highly secure VPN authentication based on line-identification information of NGNsand legacy networks is achieved
■ Method for synchronization of data between remote regions by using low-costdatabase middleware
■ RADIUS authentication architecture that can flexibly handle additional functions■ VPN session information can be provided for host Applications■ Systems can still be provided when architecture is degenerative
