bandwidth-throttling

问题 I plan to use C# to implement the bandwidth control system. I need to implement the system that can allow the system user to set a bandwidth rate to the computer user. How can I do that? 回答1: Maybe you can begin to have a look at the following question: Limit Bandwidth Speeds You might also consider having a look at TokenBucket and LeakyBucket implementations, as well as some Rate Limiting concept, for you to implement your own system. 来源： https://stackoverflow.com/questions/5908695/create-a

问题 I want to run few performance tests with different n/w speeds and read that fiddler can help in that. I modified the request-trickle-delay and response-trickle-delay params in the custom rules script file and selected the Simulate Modem Speeds flag. Nevertheless it does not help in controlling the bandwidth and the download time continues to be the same when I try testing my settings. Even when I set the delay to "5000" it does not show any difference. I believe I am missing something though

问题 Generally in a packet pair estimation, you are supposed to send multiple bursts of packet pairs and take an average of the bandwidths. Say, you send 4 packets, calculate the time difference between the first two packets(1&2), time difference between the next two packets(3&4). Calculate bandwidth for each of these two and then take average. Or Calculate the time difference between (1&2), time difference between (3&2), time difference between (4&3)... and then take an average out of these

问题 I'm a beginner to golang. Is there any way to limit golang's http.Get() bandwidth usage? I found this: http://godoc.org/code.google.com/p/mxk/go1/flowcontrol, but I'm not sure how to piece the two together. How would I get access to the http Reader? 回答1: There is an updated version of the package on github You use it by wrapping an io.Reader Here is a complete example which will show the homepage of Google veeeery sloooowly. This wrapping an interface to make new functionality is very good Go

问题 I would like to make the following happen: My application runs on a Windows machine (call it application A). I can modify the source code of application A to introduce bandwidth throttling. I would like to be able to reuse my bandwidth throttling code and drop it into any other applications that I have (in other words, I would like to try and throttle the bandwidth on an application domain level in order to not have to re-factor existing applications for bandwidth throttling). I want to

问题 I am using netty to devlope application which will listen on specific port over TCP. Once bytes received, I have a pipeline with business logic to run on received bytes. This pipeline consist of multiple channel handlers like header decoder, application level fragmentation handler etc. At the end of pipeline, once message is processed, last handler in pipeline (say BufferWriter) will put processed message into a blocking queue. This blocking queue is acting like buffer, and BufferWriter is

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: How do you throttle the bandwidth of a socket connection in C? I'm writing a simple FTP server in C for a Unix environment. As a feature of the server, I want to limit the upload/download speed of a user. Are there any library functions directly solve this problem? If not, what's the algorithm used in a production FTP server? I have a very naive solution: calculate how many bytes to send in a second, say x ,

问题 Is there a way to limit the bandwidth used by an NSURLConnection, or I'm forced to use CFNetwork methods? 回答1: Yes, but it's not pretty (it works according to this mailing list post): Start NSURLConnection on a background thread (you'll have to set up a run loop). Sleep in -connection:didReceiveData: . Forward your data to the main thread in a thread-safe fashion. The third bulletpoint is a little tricky to get right if the delegate is a UIViewController , but something like this should work
