 KCP normal mode uses the same fair concession rules as TCP, i.e., the send window size is determined by: four factors including the size of the send cache, the size of the receive buffer at the receiving end, packet loss concession and slow start. However, when sending small data with high timeliness requirement, it is allowed to select skipping the latter two steps through configuration, and use only the first two items to control the transmission frequency, sacrificing some of the fairness and bandwidth utilization, in exchange for the effect of smooth transmission even when BT is opened.

    KCP正常模式同TCP一样使用公平退让法则，即发送窗口大小由：发送缓存大小、接收端剩余接收缓存大小、丢包退让及慢启动这四要素决定。但传送及时性要求很高的小数据时，可选择通过配置跳过后两步，仅用前两项来控制发送频率。以牺牲部分公平性及带宽利用率之代价，换取了开着BT都能流畅传输的效果。
