[Question] Control the download speed/upload speed on SSL stream

[laper32]

I want to upload a file to a server, but I want to control my upload rate. Since we are now using SSL, however, I have no idea how to control the rate under this case...

The tcp_stream have function to control the rate directly, so what should I do in order to control the rate with the ssl_stream? cuz I've searched the code about ssl_stream, that I didn't find anything about controlling the rate...

Perhaps it may be a little mess since it is not well organized.

You can either intersperse each invocation of async_read_some with a delay based on how much data was read since the last read, or you can write your own rate_limited_stream type that implements the AsyncReadStream concept.

The first method is the easiest.

Are you using HTTP or Websockets? Callbacks or coroutines? If you need more guidance I can write a little demo.

Are you using HTTP or Websockets?

In fact I'm now using both (my library is required to support both of them)

Callbacks or coroutines?

Oh really? I just thought how can I implement it. Thanks for your kind

@madmongo1 How'd you go about this? Drop in a delay between calls to async_read_some? I wonder if rate-limited ops could be a nice demo of async_compose

Couple of ways, depending big on whether you’re looking to have a hard cap on bit rate or want to have a constant average bit rate.
