Towards a versatile transport protocol

In the context of a reconfigurable transport protocol, this paper introduces two protocol instances based on the composition and specialisation of the TFRC congestion control and Selective Acknowledgment mechanisms. The two resulting transport architectures lead respectively to the QTPAF protocol, specifically designed to operate over QoS-enabled networks and the QTPlight protocol, specifically designed for resource-limited end systems connected to powerful servers. QTPAF combines QoS-aware TFRC congestion control with full reliability to provide a transport service similar to TCP but additionally taking into account network-level bandwidth reservations. QTPlight proposes a modification of TFRC that shifts from the receiver to the sender the complexity of the loss rate estimation mechanism. This modification allows to alleviate the processing and communication load of “light” resource limited mobile receivers. We present the concept of these protocols and their adaptation in ...
