The Gulliver Project is a distributed measurement project aiming to observe the global behavior of the Internet from all over the world, especially from peripheries in the Internet topology. The existing measurements are taken mostly at places close to the Internet core, and measurements from peripheries are very limited. However, views from peripheries such as developing regions are crucial to understanding the global behavior of the Internet.
There are many challenges to deploy measurement platforms in developing countries due to the lack of human resources and infrastructure. A measurement platform needs easy installation and remote maintenance, to be robust against instability and failures of power and connectivity, and should be secure even against physical burglaries. Another important challenge is how to remotely manage a large number of platforms.
We use a small diskless box as an active measurement probe. The probe runs a variant of NetBSD and has remote management framework built into the firmware. These probes are remotely managed by a set of servers. For example, the probes can be instructed to perform measurement and report the result to the server or to update its firmware through the GUI on the server.
This is a letter from us of inviting you to the Gulliver Project.

When you accomodate our measurement box, we issue a member account to you. If you have your username and password already, please log in the member page. You can find in-depth data and graphs using interactive interfaces. |
As of July 2010, 34 measurement probes are deployed worldwide. Currently, the probes are performing DNS measurement, and the results are collected and archived at a server.
We will deploy 50 more probes. We are working on adding a topology measurement capability to the probes.
If you are interested in accommodating a measurement box, please contact to sekiya_wide.ad.jp (Please replace _ by @).
The graphs show reachability, loss rate and times of Anycast ID change of ROOT DNS servers measured from SEIL locations during 00:00:00 - 23:59:59 on 2010-07-29 UTC.
The graphs show RTT distribution to Root DNS servers from each location. If you are a member of the project, you can see more detail graphs including Anycast ID information by Root DNS servers.
The core members of the project are Yuji Sekiya, Kenjiro Cho and Yohei Kuga. This project cooperates actively with
and partner organizations accomodate measurement probes. We are grateful for their cooperation.
Partner organizations as of July 2010 are
