| Summary: | In this paper, we report an investigation on the impact of large block Forward Error Correction (FEC) with Drop Tail (DT) and Random Early Detection (RED) queue policies on network performance and quality of video streaming.FEC is a technique that uses redundant packets to reconstruct dropped packets, while DT and RED are the most popular queue management policies used in network routers.DT mainly depends on the size of the queue buffer to decide on whether to drop a packet or not.RED monitors the average queue size and drops arriving packets probabilistically.The probability of dropping a packet increases as the estimated average queue size grows.In the investigation, we consider simulation settings with varying size of queue buffers.Results obtained from the simulation experiments show that large block FEC and queue size affect the performance the network.Consequently, the qualities of multimedia applications are also affected. |
