Abstract
A new approach of modeling of NFV infrastructure based on network calculus theory is proposed. The proposed approach gives possibility to modeling and analysis “end-to-end” time and performance quality of service (QoS) characteristics that dependent on current state of infrastructure components. The modeling the characteristics of computing nodes of NFV infrastructure is determined by term of arrival, service and backlog curves. The calculation values of such network characteristics of the computing nodes as delay and processing speed is given; the equation, making it possible to estimate the “end-to-end” processing delay and queue length is formulated based on partial obtained results.
