Real time TCP QoS monitoring in wireless ATM CDMA networks using aggregative large deviation principle

We present a buffer management scheme called dynamic resource allocation (DRA) that provides TCP traffic control guarantees to virtual channels (VCs) carrying multiple dynamic discard thresholds (MDT) over a wireless ATM network. A major task related to these systems addresses the call admission control and resource management. It is assumed that we have TCP wireless ATM networks integrating the code division multiple access (CDMA). The MDT scheme classifies the traffic into several classes and maintains a separate dynamic threshold buffer for each class. DRA is used on a FIFO buffer shared by several VCs. The DRA scheme offers an intelligent policy-based approach to traffic prioritizing, load balancing, and accounting that controls the most critical areas of the TCP rate monitoring using the large deviation principle. Through its advanced traffic control algorithms, the DRA guarantees minimal packet loss or retransmission, optimizes TCP throughput, and optimizes the use of the network to its maximum potential.
