bandwidth

I want to get Network Connection Bandwidth in kbps or mbps. if the device is connected to wifi then it should returns the network bandwidth(speed) as well as mobile data. it will returns wifi capablity rate but i want exact data transfer rate. public String getLinkRate() { WifiManager wm = (WifiManager)getSystemService(Context.WIFI_SERVICE); WifiInfo wi = wm.getConnectionInfo(); return String.format("%d Mbps", wi.getLinkSpeed()); } You can't just query for this information. Your Internet speed is determined and controlled by your ISP, not by your network interface or router. So the only way

I was wondering if anyone knew of a way that you could manage bandwidth within a rails application in some way that isn't dependent on the web server. For example each account has a bandwidth limit. In and out bound traffic subtracts from the monthly allowance? One option would be to add an after_filter in application.rb (so that it applies to all actions) and do the following: def store_bandwidth_usage response_size = response.body.size # Assuming the User model has a bandwidth_usage attribute @current_user.increment!(:bandwidth_usage, response_size) end Of course then you would need a before

I'm attempting to send multichannel audio over WiFi from one server to multiple client computers using UDP broadcast on a private network. I'm using software called Pure Data, with a UDP broadcast tool called netsend~ and netreceive~. The code is here: http://www.remu.fr/sound-delta/netsend~/ To cut a long story short, I'm able to achieve sending 9 channels to one client computer in a point-to-point network, but when I try to do broadcast to 2 clients (haven't yet tried more), I get no sound. I can compress the audio and send 4 channels compressed (about 10% size of uncompressed) over UDP

Simplified, I have an application where data is intended to flow over the internet between two servers. Ideally, I'd like to test at what point the software ceases to function. At what lowerbound limit (bandwidth, latency, dropped packets) do things stop working to test the reliability of the software. What I thought I would do was the following: Setup up 3 machines (VMware instances) Install the 2 applications on two of the servers. Setup up the 3rd server to sit between the two machines by doing some sort of magic with Routing and Remote Access on Windows 2003 Install either Traffic Shaper

This question already has an answer here: iPhone Data Usage Tracking/Monitoring 7 answers I am trying to understand how does an app like DataMan work. Even if it runs on the background, how can it measure the bandwidth allocation of the other apps? Most apps like that inject a proxy to all your data calls. Through that they measure the amount of bandwidth you are consuming. There is no way to measure data you are using outside of your app. You can track it for your own network call within your app though. 来源： https://stackoverflow.com/questions/4375441/how-to-keep-track-of-the-network-traffic

If we: 1) Count bytes/bits at the network adapter level (raw # of bits through the NIC) and, 2) Count bytes in all HTTP/S request/responses. Assuming only HTTP/S traffic is on the box, and assuming a statistically relevant amount of "typical" web traffic: I want to know about how much more traffic will be counted at the NIC level than at the HTTP/S level (counting http headers and all) because of the extra network overhead. Franci Penov You have zero knowledge about the layers below HTTP. You can't even assume the HTTP request will be delivered over TCP/IP. Even if it is, you have zero
