With the need for mobility and wireless communications now being motivated by the commercial sector, more attention must be given towards IP QOS in the wireless infrastructure, if existing or emerging services are to be commercialized over it. In this work, we investigate and propose a system approach to balance time-varying, space-varying (usage) wireless and mobile channel conditions against IP-based service differentiation and end-end service requirements. The proposed solution leverages network programmability [1], multiple timescales, feedback-based mechanisms across flows, mobile clients and a centralized RAN or LAN control point to configure QOS policies and coordinate state information between congestion control, bandwidth control and reliability mechanisms.
