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.

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.

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.

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 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.
