设置TCP_NODELAY是否会影响套接字两端的行为? [英] Does setting TCP_NODELAY affect the behaviour of both ends of the socket?

问题描述

我一直认为Nagle的算法会在两个方向上影响套接字，并且设置TCP_NODELAY会以某种方式通知远端也要关闭Nagle.

I've always assumed that Nagle's algorithm affected the socket in both directions, and that setting TCP_NODELAY somehow informed the remote end also to switch off Nagle.

是正确的，还是设置TCP_NODELAY仅影响调用它的一端的行为?

Is that right, or does setting TCP_NODELAY only affect the behaviour of the end that calls it?

推荐答案

TCP_NODELAY仅影响在套接字上设置了此选项的主机上发送TCP段.也就是说，对等体的发送算法不受影响.

TCP_NODELAY affect sending TCP segments only on the host that sets this option on its socket. That is, the peer's sending algorithm is not affected.
