Deployment Considerations for Information-Centric Networking (ICN)
Abstract
Information-Centric Networking (ICN) is now reaching technological
maturity after many years of fundamental research and
experimentation. This document provides a number of deployment
considerations in the interest of helping the ICN community move
forward to the next step of live deployments. First, the major
deployment configurations for ICN are described, including the key
overlay and underlay approaches. Then, proposed deployment migration
paths are outlined to address major practical issues, such as network
and application migration. Next, selected ICN trial experiences are
summarized. Finally, protocol areas that require further
standardization are identified to facilitate future interoperable ICN
deployments. This document is a product of the Information-Centric
Networking Research Group (ICNRG).

1. Introduction
The ICNRG charter identifies deployment guidelines as an important
topic area for the ICN community. Specifically, the charter states
that defining concrete migration paths for ICN deployments that avoid
forklift upgrades and defining practical ICN interworking
configurations with the existing Internet paradigm are key topic
areas that require further investigation [ICNRGCharter]. Also, it is
well understood that results and conclusions from any mid- to large-
scale ICN experiments in the live Internet will also provide useful
guidance for deployments.
So far, outside of some preliminary investigations, such as
