Path Aware Networking: Obstacles to Deployment (A Bestiary of Roads Not
Taken)
draft-irtf-panrg-what-not-to-do-02
Abstract
At the first meeting of the Path Aware Networking Research Group, the
research group agreed to catalog and analyze past efforts to develop
and deploy Path Aware technologies, most of which were unsuccessful,
in order to extract insights and lessons for path-aware networking
researchers.
This document contains that catalog and analysis.
