PROJECT TITLE :

A Dynamic Service Class Mapping Scheme for Different QoS Domains Using Flow Aggregation

ABSTRACT:

This paper addresses the issue of provisioning finish-to-finish quality of service (QoS) for multimedia services over heterogeneous networks and introduces a parametric model by using network calculus theory for QoS class mapping between completely different QoS domains. Then, a QoS mapping theme primarily based on flow aggregation (QMS-FAG) is proposed in this paper to mitigate the information loss drawback thanks to mapping between QoS domains with totally different granularity of QoS class and to provide efficient network resources utilization by considering user's quality of expertise. In QMS-FAG, the QoS requirements of service flows are indicated by a distinctive FAG identifier, which is described in a very service flow map of QoS parameters. With FAG identifier and mapping executors sitting at the border of different QoS domains, QMS-FAG permits smooth QoS class mapping between networks with completely different granularity of QoS class. Both numerical analysis and simulation studies are given to demonstrate the efficiency of the proposed methodology.
