Abstract

TCP/IP protocols make minimal assumptions about the capabilities of a link layer used to carry IP packets between nodes. The recent evolution of IP-based mobile and wireless communication has driven the design of wireless link layers and new features, including support for different QoS levels, are being included in the new link layer designs. The current IP QoS architectures are based purely on IP-layer decision making, packet buffering and scheduling through a single link-layer service access point. However, mobile wireless networks pose new challenges for IP QoS architecture implementations. In this paper, we introduce a generic convergence layer interface for controlling the capabilities of wireless network interfaces. Emphasis is on discovering the link layer functionalities and mapping IP QoS mechanisms to the available link layer features. Issues such as packet buffering and scheduling are discussed.
