Before revision: Guaranteeing accurate worst-case bounds on the end-to-end delay that data flows experience in communication networks is required for a variety of safety-critical systems , for instance in avionics . Deterministic Network Calculus (DNC) is a widely used method to derive such bounds.
After revision: Guaranteeing accurate worst-case bounds on the end-to-end delay that data flows experience in communication networks is required for a variety of safety-critical systems and certification demands the provision of guarantees for data transmissions . Deterministic Network Calculus (DNC) is a widely used method to derive such bounds.
