Glasnost网站提供了测试BT下载流量限制的测试工具，许多国内各地的网络服务提供商（ISP）都对采用BT下载采用了限制措施，使用该工具可以进行测试。Glasnost网站提供了测试BT下载流量限制的测试工具，许多国内各地的网络服务提供商（ISP）都对采用BT下载采用了限制措施，使用该工具可以进行测试。
功能介绍：某些ISP们已经对他们的客户进行了速度限制或者阻止BitTorrent流量传输。我们这里已经有了一些测试结果，当然仅是一小部分ISP们对BitTorrent流量进行了操纵。 直到今天，没有经验的互联网用户是无法获取这方面的证据的。
这个测试工具包建立一个类似BT在用户机器和用户间进行传递的机制，来确认是否ISP进行了传输操纵。测试可以使得ISP对客户的传输操纵更加透明。
你都能测试什么？
我们的测试集中在许多ISP商可能希望操纵的大多数BT传输所使用的协议上，这种类型的传输可通过端口来确认（TCP端口：6881等），或者出现在传输包的包头。因此，我们设计的在线测试工具探测你的ISP商是否使用了下面技术中的一种：
1.控制所有的BT传输；
2.在广泛使用的BT端口控制全部传输；
3.在广泛使用的BT端口仅控制BT传输；
需要注意的是，某些ISP只是在流量达到一定数值后才开始控制BT传输。因此，即使通过我们的测试表明ISP没有进行BT传输控制，也并不意味着其绝对没有对你的网络连接进行控制。
测试说明：
1.我们的测试运行机制类似TCP下载和上传，在BT端口和非BT端口进行；
2.有两种选择：简单测试需要花费大约4分钟时间，每个单独的传输需要10 秒。完整的测试中每个单独的传输需要20秒，以收集更多的数据，更加准确的确认你的网络连接。
需要注意的是，在测试的过程中，你不要在后台运行大的下载任务。

界面原文：
Certain ISPs have been shown to rate limit or block BitTorrent traffic sent by their customers. While there are multiple reports of this on the web, only a few ISPs have admitted that they manipulate BitTorrent traffic. And, to date, it is hard for users without networking expertise to gain evidence about the behavior of their ISP.
This test suite creates a BitTorrent-like transfer between your machine and our server, and determines whether or not your ISP is limiting such traffic. This is a first step towards making traffic manipulation by ISPs more transparent to their customers.
What can you test?
Our test focuses on the popular BitTorrent protocol as many ISPs are suspected to manipulate BitTorrent traffic. This type of traffic can be identified by the port it is sent on (e.g., TCP port 6881) or by BitTorrent content headers which occur in the packets.
Therefore, we designed our online tool to detect whether your ISP is using one of the following techniques:
Throttling all BitTorrent traffic.
Throttling all traffic at well-known BitTorrent ports.
Throttling BitTorrent traffic only at well-known BitTorrent ports.
Note that some ISPs do not throttle all BitTorrent traffic but only if this traffic exceeds a certain threshold. Thus, passing our tests does not necessary mean that there is no throttling occurring on your link.
Our test runs BitTorrent and TCP downloads as well as uploads on a well-known BitTorrent port and a non-BitTorrent port.
There are two test configurations available. The simple one takes approximately 4 minutes and each individual transfer is 10 seconds long. The full testset runs each transfer for 20 seconds and collect more data points and allows us to infer the status of your link with higher confidence.
Note to all users: To allow accurate measurements you should stop any large downloads that might run in the background.
