智能手机上的Android Tune TCP流量控制？

Question

I am new to ANdroid development (but have worked on linux)..We can tune TCP parameters(window size..etc) to get better performance on desktop's either windows or linux.

Was wondering can we do the same on andriod based smart phones? ...i was informed that only on root access devices we can do it...how about non-root access devices?

This for all TCP based connections initiated from android device and not specific to a socket. I was solution something similar to what we do desktop/laptop's ....ie configure the TCP parameters in the OS example increasing windo size. so that any further connections started/initiated from the box would use that as the default value... Thx in advance

Answer 1

This sounds like you aren't working with an app, you want the whole system(2g/3g/4g/wifi etc.) to move faster, correct?

In that case you must be rooted and the solution to your question is to flash a custom kernel that supports those options in its network stack.

With a custom kernel you can easily set the TCP congestion algorithm to your preference.

Answer 2

There are Socket.setSendBufferSize() and Socket.setReceiveBufferSize() . I don't see any reason why root privileges should be required.
