Have you ever notice a speed reduction when you download from torrents or when you are watching flash video, while surfing seems normal? This may be cause by your ISP that limits your bandwidth when specific behavior is noticed. Glasnost can test if your ISP is shaping your traffic, by measuring and comparing the performance of different application flows between your host and our measurement servers. The tests can detect traffic shaping in both upstream and downstream directions separately. The tests can also detect whether application flows are shaped based on their port numbers or their packets' payload.
Visit Glasnost to make your ISPs' traffic shaping policies transparent.
