In this paper, we propose a high-speed UDP-based media transport with an adaptive error control. The proposed adaptive transport scheme controls the adaptive forward error correction (FEC) and automatic repeat request (ARQ) schemes by monitoring underlying networks so that it can effectively adapt to the fluctuation of given high-speed networks. The monitored feedbacks from the receiver enable the sender to aware of current reception status (i.e., rate/type of packet loss and packet delay). Based on this, the proposed adaptive media transport attempts to provide controlled reliability by adaptively controlling ARQ as well as adaptive FEC schemes. Experiments with high-speed network testbed have been conducted to verify the performance of the proposed transport that demonstrates the enhanced throughput at the speed of up to one Gbps.© (2004) COPYRIGHT SPIE--The International Society for Optical Engineering.
