GLASNOST: Test if your ISP is shaping your traffic |
======================================================
The goal of our Glasnost project is to make access networks, such as
residential cable, DSL, and cellular broadband networks, more transparent
to their customers.
ISPs are increasingly deploying a variety of middleboxes (e.g., firewalls,
traffic shapers, censors, and redirectors) to monitor and to manipulate
the performance of user applications. Most ISPs do not reveal the details
of their network deployments to their customers. We believe that this
knowledge is important to help users make a more informed choice of their
ISP. Further, such knowledge is also useful for researchers designing
protocols and systems that run on top of these networks.
