Abstract

Systems and methodologies are described that facilitate providing quality of service (QOS) functionality on a host device or tethered processor to conserve resources on a network device. In particular, the host device/tethered processor can classify QOS data and manage QOS flows, transmitting data by flow to the network device. The data from the QOS flows can be tagged to identify the flow and/or characteristics thereof allowing the wireless device to simply route the data to its respective flow. Thus, the network device is saved from such classification and flow management freeing resources to provide increased performance and decreased power consumption.
