A modern home could contain a large variety of devices and all of them should be able to work together so as to bring a rich experience to the users. Quality of service (QoS) is a critical factor for measuring user satisfaction. It represents the ability to provide different priorities based on the type of the data flows or to guarantee a certain quality of performance to a particular service. Different devices may follow different protocols and each protocol has its own QoS management scheme. These QoS schemes are not necessarily compatible with one another and the inconsistency will significantly impair their efficacy. In this paper, we propose a harmonized protocol for home networks, which unifies all other protocols and solves the inconsistency problem effectively.
