Structure of NGN
Study/Standardization in Japan
TTC (Telecommunication Technology Committee)
• Develops NGN-related technical standards as a committee to
establish telecommunication related standards and protocols
• Created NGN architecture WG and NGN upstream SWG in
April 2005
• Collaborates and contributes to ITU-T and various foreign fora
such as 3GPP and 3GPP2
Next Generation IP Network Promotion Forum
• Combines strength of operators, vendors, academies, domestic
fora and application vendors to promote all-IP networks
• Established in December 2005, 211 members (March 2006)
• Promotes interoperability tests, demonstration experiment,
information exchange as well as standardization based on R&D
• Technological focus: QoS and function, dependability (security
and safety), interoperability and interconnectivity

• Interconnectivity test planning, promotion and coordination,
including the coordination with relevant fora
• Studies regulatory issues of IP telephony, in particular QoS and
•
functionality, safety and security,
interconnectivity and
interoperability as well as regulatory issues of other advanced
services. Practices proving test, if necessary.
• Promotes R&D and the standardization of its results by
establishing basic strategies and promotion methods, and by
practicing proving tests. R&D focuses not only on NGN R1&R2,
but beyond R2.
• Promotes deployment and information exchange of next
generation IP networks. Publicize appropriate information through
publications, symposiums and market promotions. Surveys
domestic and international R&D trends.

Important issues of NGN
Study/Standardization in Japan
 QoS and Functionality
 How should we deploy, measure, standardize and regulate QoS? What are the
appropriate regulations for emerging services, considering the heterogeneity of
future networks?
 What can be and should be standardized and regulated as basic service and
emergency service functionalities? Can NGN provide enough quality for FAX or
modem communications?
 Dependability (safety, security & reliability)
 How should we protect emergency communications, end-user privacy, cyber
attacks and prevent forgery of user IDs, without violating network’s ability to trace
criminals?
 What should be done to make NGN reliable as PSTN/ISDN?
 Interconnectivity and Interoperability
 Specifications on terminals and user/control/management interfaces, including
tests, security, numbering and addressing, charging, information exchange with
other providers.

Making NGN as dependable as
PSTN/ISDN
 Reliability of social infrastructure differs from each component’s reliability
 Must prevent social panic (by providing mend forecasts in case of failures,
tracing criminals in case of attacks, etc.)
 Administration method must align with cultural just (privacy, copyright, etc.)
 Accumulation of component’s reliability is not enough. Must be reliable from
subjective view --- dependability.
 Dependability is the key differentiator of NGN with the Internet
 We must integrate IT technology’s reliability/security/safety standards with
telecom’s standards; we have even more servers and storages in our networks
 We must find a way to keep NGN open and still dependable
 We must develop methods to control unknown applications.
QoS must be guaranteed to such applications
 We must develop criteria/standards to kick out malicious terminals and bot terminals
(terminals infected to malicious software and controlled from crackers)
 Criteria/standards must be applicable to tiny providers
