The modern industrial network traffic consists of an increasing amount of soft real-time flows, which can tolerate very small delay and losses. Allowing probabilistic Quality of Service (QoS) violation for these flows can greatly help to improve resource utilization. However, the improvement depends on the statistical properties of competing independent flows. The notion of effective bandwidth summarizes the statistical properties and QoS requirements of a flow. This paper suggests the usage of effective bandwidth to describe the arrival process of the flow along its path in a network within the framework of the statistical network calculus. Further, we improve the existing formal relationship between effective envelope and effective bandwidth to achieve a better bound for the arrival process. This new approach enables efficient utilization of statistical multiplexing of independent flows both at the ingress of the network and along the path of the flow.
