bandwidth

问题 Is there any way in Win32 to programmatically determine the bandwidth of a given network interface without actually transferring any data? I only want to distinguish between different types of interface (e.g. dialup vs DSL vs LAN), so a rough order of magnitude is fine, I don't need to actually measure the bandwidth. Background to the problem is that my application is very bandwidth-hungry, and I want to display a warning to the user if they try and run it over a low-bandwidth interface, e.g.

问题 We have an option to check the network connection types in Android (whether it is 3G, edge or gprs). I need to check the the bandwidth rate. I need to initiate a call. For that I need to check the bandwidth rate. Above a particular bandwidth only I need to make visible an option for a call (to initiate a call). I need to find the connection speed programmatically (connection speed for Mobile Data Link, EDGE). 回答1: You can download a known-size file from your server, and calculate how long did

问题 I have a simple website which makes a little use of jquery but it is not essential so I would like to skip the jquery download if the users connection is slow. Ideally I would detect a slow connection but I suppose detecting a mobile phone might be a reasonable proxy for this. If this is possible I would then remove the parts of the page which use jquery and add them dynamically if jquery is loaded. Options I have considered are: Test the connection speed by downloading a small image Download

问题 I'm working on campus project using PHP and CodeIgniter. It's only a project for my assignment. Then it comes that i have to limit bandwidth used by user (of app, not linux user). And i have no idea to implement this. I wonder if someone know the logic or ever work on the similar tasks. What basically i need is, how to track that user (system user, not linux user) bandwidth? Should i count every requests and responses for that user? How to count for imagse and static files download for

问题 I am trying to make a simple polling service using rxjs and angular 7 and am running into a recurring issue that my requests are only actually being fired once but the interval completes successfully with no errors. My service component looks like this: import { HttpClient, HttpHeaders, HttpRequest } from '@angular/common/http'; import { interval, Subject } from 'rxjs/index'; import { exhaustMap } from 'rxjs/internal/operators'; constructor( private httpClient: HttpClient ) { } getPing() {

问题 I am developing an android video-streaming application where I must detect internet speed to adjust my stream quality according to that speed. I've searched in the net about how to detect internet speed in android but I found only one method of downloading file and knowing its size to determine the bandwidth : bandwidth = contentLength / ((endTime-startTime) *1000); Is there any other possible way to determine internet bandwith in android without downloading any file I don't want to disturb

At our new office we have a bit of a problem with file sharing. Currently we are using DropBox, but we'd prefer to use SVN because of all the extra features. The nice thing about DropBox is, as far as I understood, that it also syncs over the LAN with other computeres, so not using the internet heavily. This is

As asked, I would like my script to check network bandwidth giving me any idea how fast user can surf through web. Is there any library, which allows me to specify size of package to be send and gives ping time or whatever? 回答1: This answer mentions a Python implementation of ping that returns the ICMP packet's

问题 I want to measure bandwidh using c#. Here what I did. Comments and suggestions are welcome. Find maximum udp payload(on my test bed, its 1472 byte) Create non compressible data with 1472 byte size Send this data from a server to a client multiple times(on my test, its 5000 packets) Client start stopwatch at the time the first packet arrive When all data has been sent, send notification to client stating all data has been sent Client stop stopwatch I calculate bandwidth as (total packet sent

问题 i want to measure current download speed. im sending huge file over tcp. how can i capture the transfer rate every second? if i use IPv4InterfaceStatistics or similar method, instead of capturing the file transfer rate, i capture the device transfer rate. the problem with capturing device transfer rate is that it captures all ongoing data through the network device instead of the single file that i transfer. how can i capture the file transfer rate? im using c#. 回答1: Since you doesn't have
