传统的TCP在高速网络中丢失恢复时间长和丢失支持率低，不能充分利用网络带宽，难以实现大数据量传输。

Traditional TCP can't make good use of the high-speed network's bandwidth because of the long loss recovery time and low loss support rate, which makes it difficult to realize bulk date transfer.

仿真结果表明，与传统链路恢复算法相比，子树恢复算法在网络资源利用上有明显的优化，也能缩短故障恢复时间。

Simulation results show that the new STP approach can improve network resources utilization compared with CRD-based schemes, and can also reduce the restoration time.
