The dependence on frequent acknowledgments (ACKs) is an artifact of current transport protocol designs rather than a fundamental requirement. Frequent ACKs waste resources when the overhead of ACKs is nonnegligible. However, reducing the number of ACKs may hurt transport performance. “Tame ACK” is an on-demand ACK mechanism that seeks to minimize ACK frequency, which is exactly what is required by transport.

确认对运输控制的要求

对频繁确认（ACK）的依赖是当前传输协议设计的产物，而不是基本要求。当ACK的开销不可忽略时，频繁的ACK会浪费资源。但是，减少ACK的数量可能会损害传输性能。“驯服ACK”是一种按需ACK机制，旨在使ACK频率最小化，而这正是传输所需要的。
