i-Path

About

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

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 have been supported as a part of the NeW Generation Network research and development funded by NICT, Japan.

Background and Motivation

i-Path project is developing a protocol stack implementation to provide the visibility of end-to-end network path. We evaluate the feasibility of our approach using the implementation on R&D testbed networks, such as, JGN2+. And, with releasing our implementation, we would like to facilitate other research activities sharing the similar cross-layer ideas.
