Accelerating Transmission of Streaming Files Based on AL-FEC Protection Blocks

In this paper, we proposed a method for accelerating the transmission of a series of streaming files for multi-session file delivery scenarios. When streaming files are transmitted, the throughput of data transmission can be increased and the out of order problem of file reception (i. e., file reception delay) can also be reduced at the same time. This is achieved by using a repair file generation mechanism based on AL-FEC, which is triggered while an empty file transmission session appears but there are still uncompleted files waiting to be delivered. Performance evaluation results shows that the file transmission throughput of the proposed method are 28% to 44% higher than the throughput of a traditional file transmission method that is designed for reducing file reception delay. However, the file reception delay is the same as the above-mentioned traditional method.
