The emerging Tactile Internet (TI) will enable control-oriented networks for remotely accessing or manipulating objects or devices. One major challenge in this context is how to achieve ultra-low-delay communication between the local operator and the remote object/device to guarantee the stability of the global control loop and to maximize the user’s quality-of-experience (QoE). Being one of the major...
Differentiated Services provide Quality of Service within a domain by aggregation of flows. There are mainly four modules which work together in Differentiated Services Classifier, Meter, Marker, and Shaper/Dropper. When congestion increases at Differentiated Services enabled router, Quality of Service is maintained according to the priority of packets by dropping lower priority packets, providing...
We investigate the problem of finding minimum-distortion policies for streaming delay-sensitive but distortion-tolerant data. We consider cross-layer approaches which exploit the coupling between presentation and transport layers. We make the natural assumption that the distortion function is convex and decreasing. We focus on a single source-destination pair and analytically find the optimum transmission...
