TCP slow-start和速率限制传入流量之间是否有任何链接？是否可以使用慢启动描述的方法人为地限制发送方的发送速率？
另外需要注意的是,我想要实现流量整形的服务器本身建立PPPoE连接,并充当网络其余部分的路由器.
更新：到目前为止的答案已经对我提出的问题进行了公平的概述,但我仍然不知道下载管理器如何能够限制传入流量,更具体地说,是否可以实现类似的策略. Linux网关盒.
解决方法
@H_404_11@ 下载管理器最有可能按照 trickle paper中的说明工作.A process utilizing BSD sockets may perform its own rate limiting.
For upstream limiting,the application
can do this by simply limiting the
rate of data that is written to a
socket. Similarly,for downstream
limiting,an application may limit the
rate of data it reads from a socket.
However,the reason why this works is
not immediately obvIoUs. When the
application neglects to read some data
from a socket,its socket receive
buffers fill up. This in turn will
cause the receiving TCP to advertise a
smaller receiver window (rwnd),
creating back pressure on the
underlying TCP connection thus
limiting its data flow. Eventually
this “trickle-down” effect achieves
end-to-end rate limiting. Depending on
buffering in all layers of the network
stack,this effect may take some time
to propagate.
如果您偶尔需要对UNIX系统上的单个程序进行速率限制,那么简单的解决方案就是trickle.真正的流量整形就像您在网关上执行一样,可以使用tc完成.这在Linux Advanced Routing& Sons的Chapter 9. Queueing Disciplines for Bandwidth Management中有记载.交通管制HOWTO.
