Abstract
This paper analyses, using Unified Modelling Language, end-users’ and applications’ common basic requirements towards a QoS enabled network. It provides the basis for a QoS description language, the so called Application Profile (AP) supporting mapping mechanisms between application, end-user and network. Based on this analysis the paper introduces five practically implemented Network Services (NS), designed for large networks with the aim to manage the resources. The underlying mechanisms at network level and QoS capabilities of routers, allowing appropriate handling of underlying Traffic Classes (TC) by adaptation of scheduling and queuing parameters, are presented. Considering the proof of the requirements active and passive measurements with high precision are introduced. Data is collected in a central database, verifying the specifications and allowing adjustments for admission control as well as technical parameters at network level.
