Flexible gateways architecture for enhanced access network services and applications

The main objective of the FlexiNET project is to define and implement a scalable and modular network architecture incorporating adequate network elements (FlexiNET Node Instances) offering cross-connect control, switching/routing control, and advanced services management/access functions at the network access points that currently only support connectivity between user terminals and network core infrastructures. The primary aim is not to replace or enhance existing networking infrastructures, but to offer a value-added complementary network architecture addressing service access de-centralisation and separation of data, service logic and control from the pure transport network.

The FlexiNET architecture will be based on the FlexiNET node instances, which will consist of scalable hardware and software platforms on top of which core network functionality will be realized, as a set of distributed sub-systems integrated into a generic services execution environment. The FLEXINET concepts and architecture are applicable to various access network technologies (GSM/GPRS/UMTS, WLANs, V5, etc.), but will be focused on the mobile and wireless operator needs (UMTS and WLAN) for packet switched applications.

The basic motivation for this project is to relieve core networks from data handling and signalling procedures overhead, to accelerate the introduction of next-generation marketable services, and increase competitiveness in the telecom field by facilitating the broadening of current business models for services provisioning and exploitation.
