Recent advances in high-speed mobile networks have revealed new bottlenecks in
ubiquitous TCP protocol deployed in the Internet. In addition to differentiating non-
congestive loss from congestive loss, our experiments revealed two significant performance
bottlenecks during the loss recovery phase: flow control bottleneck and application stall,
resulting in degradation in QoS performance. To tackle these two problems, we first develop
a novel opportunistic retransmission algorithm to eliminate the flow control bottleneck, which …
