Towards a QoS - Aware ODP Computational Viewpoint

Oussama Mohamed REDA

Abstract: QoS characteristics are fundamental to the expression of QoS requirements in ODP system. A QoS characteristic represents an identifiable ad quantifiable aspect of a system, a service, or a resource. Examples of usual temporal QoS characteristics relative to interactions between two objects are: transit delay, jitter and throughput. Specifications of such temporal characteristics require two interaction points. The ODP computational model of interfaces is complex and contains inconsistencies which make specification of QoS on computational entities a difficult task. End-to-end QoS Characteristics can only be defined on primitive (atomic) computational entities. This work proposes a simple model of primitive computational interfaces and interactions which intrinsically support the definition (specification) of end-to-end QoS Characteristics in a computational specification.
