Services over IP
Business Oppotunities and Challenges
• Service Provider Challenge: Remain profitable facing increasing competition
• The solution: use Market and Technology opportunities to do things dramatically different
• The market: The urgent need to change from costsaving strategy to increasing the averagerevenueperuser by offering value added and more personalized services
• The technology: the introduction of IP technology in all the areas of SP’s network and the improvement of access technologies.

Business Opportunities and ChallengesThe market: Creating the demand
1 TelepresenceTelepresence is the ability to interact in realtime with another person who is at a different location using telecommunications. Telephony is a telepresence application in its most simple form. 3D Imaging:Adding three dimensional aspects to the imaging systems of telepresence will further enhance the experience of telepresence. Virtual Reality: that applications will develop blend reality and virtual reality forming hybrid realities to enhance our experiences. An example of this could be a type of visual display that could project images onto a user’s normal field of view, allowing them to receive augmented information relating to their environment such as directions to the nearest hospital or police station.

2 TeleLearning/TeleEducation3 TeleMedecine
The first transatlantic telesurgical procedure was recently successfully carried out using a 10Mbit/s link between surgeons in New York and a patient in Strasbourg, France
Home Care: Home care involves monitoring and caring for patients at home using telecommunications technology.

Step3: Traffic Engineering and Quality of Service in Packet Switched Networks
• Techniques such as DiffServ, IntServ and MPLS enable connections to be made or capacity to be reserved over packet switched networks giving them traffic engineering capabilities.
• This new breed of multiservice network is known as a Next Generation Network and can take many different forms in different circumstances to achieve the required service levels.
Next Generation NetworksGenesis(suite)
SoftswitchesSoftswitchesThese are devices that can be programmed to act as gateways allowing communication between packet based networks (e.g. IP) and traditional circuit switched networks. E.g. VoIP services and circuit switched telephony services
DSLAMDSLAMDigital Subscriber Line Access Module, used to connect multiple DSL users to the rest of a network. A multiservice DSLAM interconnects to voice networks as well as other data networks.
Next Generation Edge SwitchNext Generation Edge SwitchA multiprotocol switch that can connect users various access methods (e.g. ISDN, Dialup modem, Analogue telephony) to next generation core networks.
Broadband Access SwitchBroadband Access SwitchConnects broadband access networks (e.g. Broadband leased circuits) directly to core networks. These devices connect network segments that are suitable for direct connection to core next generation networks.
Next Generation Network Elements
Next Generation Networks: (ITU G805)• Packetbased transfer of user, control and management• Broadband capabilities with QoS• Separation of the service related functions and the
transport related technologies• Access to different SPs independent from transport
technology• FixedMobile convergence resulting in converged
services.

Architecture considerations for resource management interface
• Resource Management Interface is defined considering:– Customer Facing Services: services that are visible
to the customer ie the exposed capabilities of the product offering
– Resource Facing Services: internally offered by the enterprise so as to be able to offer the functionalities defined in the product
– The transmission technology layering used

SoIP/NGN Management
Need for standardized Framework Approach• Increasing number of vendors offering increasing network capability.• Interoperability between vendors is a must.• Increasing cost of integration.
Work on NGN Management• ETSI TISPAN: Telecom Internet converged Services&Protocols for
Advanced Networks• ITUT SG4: Study Group on management• ITUT FGNGN: Focus Group on NGN
SoIP/NGN Management
OSS interface is determined by:• A set of operations (requests/responses)• Notifications of OSS Components that are potentially
accessible from other OSSsRelationship model between OSSs• Client/server Schema• Loose communication by a communication bus
