The goal of the Glasnost project is to make ISPs' traffic shaping policies transparent to their customers. To this end, we designed Glasnost tests that enable you to check whether traffic from your applications is being rate-limited (i.e., throttled) or blocked.
Glasnost tests work 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
