Abstract

Providing quality of service (QoS) guarantees in packet-switched networks like the Internet has been and still is an important research area. In particular, it is important to ensure strict (deterministic) guarantees for highly time-sensitive data flows. In this paper, we discuss how to efficiently allocate service curves for deterministically guaranteed services. We focus on bandwidth/delay-decoupled service disciplines and their respective service curves due to their distinct advantages over purely rate-based schedulers. Resource-optimal network service curves for deterministic service flows scheduled by bandwidth/delay-decoupled service disciplines are derived and their performance is discussed by numerical examples.
