URG: The "Urgent" flag signals to the TCP application that the payload data must be processed immediately up to the set Urgent pointer (see above). ACK: In combination with the acknowledgment number, the ACK flag acknowledges the receipt of TCP packets. If the flag is not set, the confirm...
需要通过 TCP 发送小型数据包时,Winsock 应用程序的设计尤其重要。 不考虑延迟确认交互、Nagle 算法和 Winsock 缓冲的设计可能会严重影响性能。 本文使用几个案例研究来讨论这些问题。 它还得出了一系列关于如何从 Winsock 应用程序中高效发送小数据包的建议。 原始产品版本:Winsock 原始KB 数:214397 背景 当Mi...
