Loss detection adopts a hierarchical local recovery method based on NAK, and the application buffer not only solves the limited buffer capacity problem because of NAK, but also advances the throughput under the different transfer rates in the net.

• 其中,差错控制采用基于NAK的分层局部恢复的方法; 而应用层缓冲区的设置不仅解决了NAK方式下缓冲区容量的问题,还缓解了节点的接收速率大于发送速率时带来的吞吐率降低现象。
