Abstract	Recently, Dynamic Adaptive Streaming over HTTP (DASH) has been widely deployed over the Internet. Under time-varying network conditions, it is, however, still a big challenge to provide smooth video bit-rate with high video quality, especially when multiple clients compete for the network resources where the fairness must be considered. In this paper, a fairness-aware smooth rate adaptation approach is designed for DASH under the scenario that multiple clients are competing for the network resources. To avoid the unfair bandwidth estimated by the client induced by the off-intervals during the downloading process, a probe-based bandwidth estimation method is designed which includes a logarithmic law based increase probing scheme and a conservative back-off based decrease probing scheme. Then, with the probed bandwidth, a dual-threshold based video bit-rate switching scheme is designed that buffer overflow/underflow is avoided, and smooth video bit-rate is also provided. The extensive experiments on our network testbed demonstrate that the proposed approach outperforms the existing schemes significantly.
