network 4 -Scalable, smart networks with superior performance
This paper describes a value-based approach to the design of fourth-generation networks and addresses key trends by describing a number of techniques that can maximize value generation. The first three generations of fixed and mobile networks were analog, digital and best-effort broadband. Each produced new challenges and opportunities for network operators. The telecom industry is entering an era in which everything that can benefit from being connected will be linked to the network. The benefit of this has been established in high-value and critical applications but now technology is enabling cost-effective connectivity for much smaller, cheaper devices. Mobile broadband is now freeing internet users from the tether of a fixed location, and operators have the opportunity to exploit their deep knowledge of individual users, their devices and their location. Network video has also taken over from peer-to-peer as the dominant traffic type, and it will continue to grow into an integral part of the consumer television experience. Delivering mass-market, quality video places tougher requirements on network design. An increasing proportion of user services from third-party service providers are being delivered through operators’ networks, in most cases only requiring the network operators to provide best-effort connectivity. This will not necessarily be the case in the future. The design techniques described in this paper can be used to address these challenges as we move into this demanding networked future while also building concrete and immediate value for the
