在现在的"延迟确认"（delayed-ACK）TCP应用中，目的端收到两个包时发送一个确认，那么只要接收到的包中有一个CE包，确认包中的ECN-Echo标志就要设置。

Delayed ACK 延迟ACK ; 延迟应答
The client selects the value of its SACK options whenever transmitting a delayed ACK.
在传输延迟的应答时客户机选择SACK选项的值。
For the non-SACK test cases, I used the typical length of the delayed ACK queue reported by the client as an approximation of the lower bound of the sender's window size.
对于非sack测试用例，我使用客户机报告的延迟应答队列的典型长度作为发送方窗口大小的近似值。
Only the limiting of the TCP sending window size is not enough, the strategy of delayed ACK is also required in the solution.
仅仅限制TCP发送窗口大小是不够的，延迟确认策略应该同时使用。
