For the layer 'System Level Functionality' of the Phyisical Internet, it is needed to estimate end-to-end performance characteristics of transportations that visit multiple logistic domains. This paper proposes an approach based on a Digital Internet functionality: a combination of a Service Level Agreement registry and a Quality of Service processor. Existing SLA-calculus gives tools for the QoS-processor to combine the SLA-parameters for all possible end-to-end paths and gives the QoS-processor the possibility to propose the best path given the required performance. A realistic implementation is proposed using a multi objective/constraint approach and a related communication form between the domain owner and the QoS Processor.
