(Continuation of Question 2/13) Motivation
With the rapid growth of IP services, including IP multimedia telephony and
IPTV, demand has been continuously increasing to enhance the network
capabilities of multi-service networks. These emerging services and evolution of
existing ones, and their variety of deployment scenarios, are placing more and
more requirements on networks and are resulting in the need to provide new
service and network capabilities. Response to this demand is calling for the
creation of an open environment whereby also third parties can develop services
and capabilities. In particular, there is now significant support for the NGN to
evolve consistently with the concepts of the service oriented architecture (SOA)
framework, thereby allowing the composition of interoperable and independent
building blocks from both Information technology and telecom domains and
enabling the integration of rich content, data applications and business
processes of the IT domain with intelligent, real-time network capabilities of
the telecom domain. Such an approach will allow for flexible and agile service
creation, operation and management, will drive development of capabilities which
are portable and reusable across networks, and will allow applications
(developed by service and network providers as well as third parties) to operate
via standardized interfaces (such as Web Services oriented APIs).
In the context of a SOA enabled next generation multi-service network
environment, study is required, on the basis of business cases and service
requirements, to develop implementation scenarios for emerging services as well
as to specify the related service and network architectures, including service
middleware aspects. These studies, in the context of an open service
environment, will allow the specification of the requirements and capabilities
imposed on networks (including user networks) by these services, with the goal
of maximizing usage of common service and network capabilities and functional
building blocks.
Key requirements to be considered are ubiquitous support of: seamless
end-to-end service operations, service access by mobile and wireline users,
wireless/wireline technology independent service access, real time multimedia
content delivery, unicast and multicast delivery technologies, SLAs and
differentiated levels of quality of service, enhanced security, service
mobility, service interworking, policy based capabilities, context based
capabilities, user identification, authentication and authorization, service
discovery, service routing, service brokering, service composition, and both
IPv4 and IPv6 protocol technologies.
Emerging services include IP multimedia telephony applications, IPTV
applications, content delivery services, business/enterprise communications,
ubiquitous sensor network based applications, identification based services,
context aware services, third party services such as managed delivery services
and others, applications of user networks (home networks), applications of grids
and related enablers, VPNs and other network virtualization applications,
managed peer to peer services, advanced data communication services, as well as
other future applications and services based on composition of open service
environment capabilities.

Question
Study will consider emerging services in next generation multi-service
network environments.
Study items to be considered include, but are not limited to:
- What activities are needed for the development of implementation scenarios
of emerging services in evolving next generation network environments, including
study of related capabilities, mechanisms and technology enhancements to support
the specified requirements?
- What activities are needed for the development of service and network
architectures, including middleware aspects, of emerging services in evolving
next generation multi-service network environments, with the goal of maximizing
usage of common service and network capabilities and functional building blocks
across different services and related business cases? Service and network
architectures should support an open service environment, and be consistent with
a service oriented architecture (SOA) approach.
- What activities are needed to support an open service environment and a SOA
approach in evolving next generation multi-service network environments?
- What Recommendations should be developed to identify requirements placed on
networks (including user networks) by emerging services in evolving next
generation multi-service network environments? Requirements for enhanced
capabilities impacting transport networks (based on IP/ (G) MPLS, carrier
Ethernet or other technologies) are included.
- What enhancements to existing Recommendations are required to provide energy
savings directly or indirectly in information and communication technologies (ICTs)
or in other industries? What enhancements to developing or new Recommendations
are required to provide such energy savings
Tasks
Tasks include, but are not limited to:
- Development of Recommendations on emerging services in evolving next
generation multi service network environments (requirements and capabilities,
service and network architectures, implementation scenarios).
- Development of Recommendations on open service environment and SOA in evolving
next generation multi-service network environments (including requirements for
telecom SOA and telecom APIs, and capabilities and components of a SOA enabled
open service environment).
- Completion of draft Recommendations currently under way.
