is this Project about?
NGN related efforts are currently focussed on core network issues (switching/routing in the transport plane, distributed intelligent service creation and provisioning in the control plane), without yet addressing the access network requirements that would enable cost effective delivery of a wide variety of innovative multi-media and broadband services to end users through various distribution systems and access network technologies (with prime focus on xDSL) to NGN services and applications.
The first aspect that needs to be addressed in the project is the identification of the most appropriate services (including voice, data, video and TV, multi-media applications) services and delivery systems (typically xDSL-based) in an NGN environment. From there it will be possible to identify access networks functional requirements for ensuring resource and service control (encompassing QoS and Security). Building upon the identified requirements, access network elements (e.g. Gateways, Proxies, Servers) needed to accommodate the service delivery over broadband access technologies will be defined, taking into account the various relevant access systems as well as the economy factors.
The second aspect of the work is to investigate how operators can reuse and integrate their existing access network infrastructures, enhanced with new and diverse access technologies, to provide a coherent and as harmonized as possible interfaces towards the emerging core NGN architectures. This aspect of the study will build upon the above identified requirements but will mostly concentrate on resource and service control aspects and on their interactions with related NGN edge and core functions, through the adoption of various emerging protocols (e.g. Megaco, SIP) and techniques (e.g. MPLS), in order to propose flexible and extensible access network architectures interfacing smoothly with NGN environments.
