Abstract
An IP oriented resource management framework is presented where QoS functionalities in the network and link layer are coupled. This can be seen as a natural evolution from current schemes deepen their roots into traditional protocol stack architectures where mechanisms between the two layers are decoupled and the inter-layer communication is solely based on mapping between QoS traffic classes. The argument to be defended in this article is that a coupled approach provides a richer set of novel resource management strategies. In that respect, and as an incarnation of this statement, a truncated rate control scheme for CDMA networks is proposed by integrating IP layer QoS information. The rate transmission of the out-of-profile packets that are beyond the contracted Service Level Agreement (SLA) is truncated if the link gain is below a certain cutoff threshold. A rate truncation with packet dropping or packet delay is proposed together with a hybrid scheme. The critical seminal aspects of the proposed scheme, which reflect the point of view we intend to uphold here, are twofold. Firstly, using different thresholds based on packet drop-precedence, the QoS experienced by in-profile packets is increased and secondly, significant power gains can be achieved by deterring to compensate for deep fades of out-of-profile packets.
