我的理解是,这两种方法都是可分辨的奈格尔算法。
我何时应该使用这些工具?

首先,他们不是两人都可以离开。 Nagle 算法。
Nagle 算法是减少更多的小型网络包裹。 算法是:如果数据少于限额(通常为MSS),则要等到收到以前寄出的包装单时,以及平均时间从用户那里积累数据。 然后发送所积累的数据。
if [ data > MSS ]
send(data)
else
wait until ACK for previously sent data and accumulate data in send buffer (data)
And after receiving the ACK send(data)
这将有助于申请电话。 然而,在等待捷克克朗时,在发送数据时可能会增加相对性。 此外,如果接收人执行延迟的科索沃警察部队政策,就会造成暂时的僵局。 在这种情况下,拆解Nagles算法是一种更好的选择。
因此,TCP_NODELAY被用于拆解Nagle的算法。
TCP_CORK aggressively accumulates data. If TCP_CORK is enabled in a socket, it will not send data until the buffer fills to a fixed limit. Similar to Nagle s algorithm, it also accumulates data from user but until the buffer fills to a fixed limit not until receiving ACK. This will be useful while sending multiple blocks of data. But you have to be more careful while using TCP_CORK.
在2.6方言之前,这两种选择都是相互排斥的。 但是,在后来的摇篮中,两者可以共同存在。 在这种情况下,将给予TCP_CORK更多的优惠。

利用Nagles算法改进TCP/IP网络,减少包装件数,直到收到以前发送的数据以发送累积包装单为止。

如果确定,不发放部分框架。 所有被问及的部分框架均在选择再次获得许可时发出。 这对于在打电话<><><>><>>>>上填写的头盔或用于优化投稿很有用。 如目前实施,在产出按<编码>计算时,有200-millisecond limit。 TCP_CORK。 如果达到这一上限,则自动传送数据。 这一选择可与<代码>合并。 TCP_NODELAY only since CESCR 2.5.71. 这种选择不应用于拟可携带的法典。
它与任何选择一样具有选择性:
基本目标是避免在使用单一框架时,用发送文件及其朋友发出若干框架。
例如,在网络服务器上,你寄送了头盔,然后是档案内容,头盔将装在册,然后由车库直接发送。 TCP_CORK允许你在单一框架内,甚至在TCP_NODELAY上,拥有头盔和档案的开始,否则就会立即寄出第一个空白。
