Such a network can be built using standard PC and Ethernet hardware and open-source software components, e.g., IP routing and traÆc control avail- able in recent Linux kernels as well as a Differentiated Services package built atop these building blocks. The testbed can exibly be configured to model various link bandwidths as well as IP routers capable of classifying, queuing (with various disciplines), forward-ing and/or dropping packets and shaping traÆc. The QoS components and facilities of the testbed are in-troduced and initial performance analysis experiments and results are reported. A simple video streaming application under QoS control is presented to show the usefulness of the testbed.}, issn = {980-07-7552-8}, keywords = {multimedia communications, quality of service, QoS, networking testbed, routing, Linux}, language = {EN}, pdf = {https://www.itec.aau.at/bib/files/A Cluster-Based QoS Testbed for Multimedia Communications.pdf}, talktype = {none} }
