英文摘要	Live Video Streaming has a strict low latency requirement. Current multipath techniques like Multipath RTP (MPRTP) and Multipath TCP (MPTCP) are not optimized to meet this requirement. This is especially true when they are operating over a wireless medium, whose channel conditions change very rapidly and unpredictably. These multipath techniques are unable to adapt quickly to the dynamic channel conditions. LTE WLAN Aggregation (LWA) is capable of dealing with this problem since it makes its decisions at the edge of the network. In this paper, we propose the bOunded delAy baSed steerIng with timelineSs (OASIS) framework over LWA for streaming live video with low latency. The OASIS framework comprises of a novel traffic steering algorithm, BOunded deLay based sTeering (BOLT). BOLT calculates the maximum traffic load which can be transmitted on each of the links (LTE and Wi-Fi) before the packets experience higher delay i.e., above a certain delay threshold. OASIS also comprises of a timeliness model, which prioritizes the packets belonging to Intra-coded picture (I-frames) over other packets. OASIS is implemented and tested in NS-3. We use NS-3 in emulation mode which allows us to stream real videos over the simulated topology. OASIS is compared with MPRTP, LWA, LTE, and Wi-Fi. We show that the proposed framework performs 1.4x better than MPRTP. Also, it outperforms all the other comparative techniques when tested under different scenarios. These scenarios are designed to test the different techniques under rapidly changing wireless medium. We also show that the quality of the video improves with the inclusion of the timeliness model.
