Framework for Flexible Multi-Metric Path Selection for Next Generation Network

Abstract

Abstract-This paper addresses the subject of multi-objective routing for an NGN environment. We propose a framework for a flexible multi-metric path selection which is designed as additional functional part for an NGN core. The framework allows the integration of user devices in NGN and a flexible definition and integration of a wide range of routing criteria. For the flexible definition of routing criteria, we propose a universal criteria raster. The proposed framework provides the users with the possibility of defining path selection rules between his devices and NGN core based on various sets of freely defined and parameterized criteria.
