This Recommendation specifies quality of service (QoS) requirements and framework for supporting deterministic communication services in a local area network (LAN). It provides a high-level model followed by the QoS requirements. Based on the high-level model and the identified QoS requirements, it specifies a framework and an example operational procedure for deterministic communication services. Finally, it provides three scenarios and associated use cases as informal material in the appendices.

The scope of the Recommendation includes:

• Introduction

• High-level model

• QoS requirements

• Framework

• Example operational procedure

Service scenarios and use cases are described in the appendices.
