Welcome to i-Path Project

About i-Path

i-Path project explores how to provide network end systems with a visibility inside the Internet.

The goal of i-Path is to realize visibility between an end-to-end Internet path with "hop-by-hop" granularity, and also, to satisfy disclosure policies among all stake holders along the path, i.e., sender, access network providers, backbones, and receiver.

i-Path project is supported as a part of the NeW Generation Network research and development funded by NICT, Japan.
