IP networks present a challenging environment for video streaming because they do not provide throughput, jitter, or loss rate guarantees. This paper focuses on improving the perceived quality of video streaming through dynamic path selection. Selecting one of several Internet paths is possible using multihoming and/or an overlay routing infrastructure. They conduct an experimental comparison of various measurement-based path selection techniques for video streaming. The path selection is based on the measurement of network-layer metrics, such as loss rate, jitter or available bandwidth, while the video quality is evaluated based on the VQM tool. The experiments show that the most effective technique for adaptive path selection relies on an estimate of the lower bound of the available bandwidth variation range.
