Packet loss reduction. For latency-sensitive applications including highly interactive websites employing technologies such as AJAX or high-bitrate video streaming, TCP can introduce significant delays when retransmitting lost packets and initiating connections. The same multi-path technology used for path optimization can be used for redundancy, and when combined with forward error correction techniques in an approach similar to [31], offers significant packet loss reduction with minimal overhead and without increasing latency, even for congested paths.
