A Model-Driven QoS Provisioning Engine for Cyber Physical Systems

Free registration required

Executive Summary

Developing cyber physical systems is hard since it requires a coordinated, physics-aware allocation of CPU and network resources to satisfy their end-to-end Quality-of-Service (QoS) requirements. This paper provides two contributions to address these challenges. The authors present model-driven middleware called NetQoPE that shields application developers from the complexities of programming the lower-level CPU and network QoS mechanisms by simplifying the specification of per-application CPU and per-flow network QoS requirements subject to the physical constraints and dynamics, resource allocation and validation decisions (such as admission control), and the enforcement of per-flow network QoS at runtime.
