RFC 7927: Information-Centric Networking (ICN) Research Challenges
We (ICNRG) published RFC 7927 on Information-Centric Networking (ICN) Research Challenges.
This memo describes research challenges for Information-Centric Networking (ICN), an approach to evolve the Internet infrastructure to directly support information distribution by introducing uniquely named data as a core Internet principle. Data becomes independent from location, application, storage, and means of transportation, enabling or enhancing a number of desirable features, such as security, user mobility, multicast, and in-network caching. Mechanisms for realizing these benefits is the subject of ongoing research in the IRTF and elsewhere. This document describes current research challenges in ICN, including naming, security, routing, system scalability, mobility management, wireless networking, transport services, in-network caching, and network management.
Information-Centric Networking (ICN) is an approach to evolve the Internet infrastructure to directly support accessing Named Data Objects (NDOs) as a first-order network service. Data objects become independent of location, application, storage, and means of transportation, allowing for inexpensive and ubiquitous in-network caching and replication. The expected benefits are improved efficiency and security, better scalability with respect to information/bandwidth demand, and better robustness in challenging communication scenarios.
ICN concepts can be deployed by retooling the protocol stack: name-based data access can be implemented on top of the existing IP infrastructure, e.g., by allowing for named data structures,
ubiquitous caching, and corresponding transport services, or it can be seen as a packet-level internetworking technology that would cause fundamental changes to Internet routing and forwarding. In summary, ICN can evolve the Internet architecture towards a network model based on named data with different properties and different services.
This document presents the ICN research challenges that need to be addressed in order to achieve these goals. These research challenges are seen from a technical perspective, although business relationships between Internet players will also influence developments in this area. We leave business challenges for a separate document, however. The objective of this memo is to document the technical challenges and corresponding current approaches and to expose requirements that should be addressed by future research work.

Privacy, Performance, Protocols: ICN Researchers meet in Prague
The IRTF Information-Centric Networking Research Group (ICNRG) had another ICN research fest with two meetings this week in Prague where IETF-93 is taking place.
ICN is an approach to evolve the Internet infrastructure to directly support information distribution by introducing uniquely named data as a core Internet principle. Data becomes independent from location, application, storage, and means of transportation, enabling in-network caching and replication. This enables the design of more robust, secure and better performing networked systems.
This week, more than 100 researchers got together to discuss recent advances in protocol development, performance optimizations, user privacy and new use cases.
One of the protocols that are developed in ICNRG is CCNx, a network protocol that provides requests (Interests) for named data and Content Object responses. The protocol semantics are specified in draft-irtf-icnrg-ccnxsemantics, and the protocol format is specified in draft-irtf-icnrg-ccnxmessages. The ICN community is currently discussing several extensions to the protocol, including support for "manifest" objects, which would facilitate the distribution of larger, chunked objects and add additional performance and flexibility to ICN systems.
Another highlight of the meeting was a presentation by Iannis Psaras from UCL on Solving the Congestion Problem using ICNPrinciples, an approach that is using Resource Pooling as a tool to manage uncertainty in congestion management.
Vasilis Sourlas (UCL) presented Information Resilience through User-Assisted Caching in Disruptive Content-Centric Networks. The corresponding paper won the IFIP 2015 best paper award and describes work from the GreenICN project. The approach relies on a modified NDN router design that features a “Satisfied Interest Table” (SIT) that enables user-assisted caching.
Bengt Ahlgren (SICS) presented on the Applicability and Tradeoffs of ICN for Efficient IoT (draft-lindgren-icnrg-efficientiot). This document outlines the tradeoffs involved in utilizing Information Centric Networking (ICN) for the Internet of Things (IoT) scenarios. It describes the contexts and applications where the IoT would benefit from ICN, and where a host-centric approach would be better. The requirements imposed by the heterogeneous nature of IoT networks are discussed (e.g., in terms of connectivity, power availability, computational and storage capacity). Design choices are then proposed for an IoT architecture to handle these requirements, while providing efficiency and scalability. An objective is to not require any IoT specific changes of the ICN architecture per se, but we do indicate some potential modifications of ICN that would improve efficiency and scalability for IoT and other applications.
Dirk Trossen (Inter Digital) presented IPoverICN – the Better IP?, a presentation of the EU-H2020 POINT project that is developing an IP over ICN system. The hypothesis of this project is that IPoverICN has the potential to run IP services better than in standard IP networks.
Mark Stapp (Cisco) presented on Private Communication in ICN. This presentation asks the question whether ICN needs better privacy protection to achieve parity with IP for user privacy in the presence of ubiquitous encryption. The discussion initiated an intensive discussion on privacy requirements for ICN that will continue in upcoming meetings.
Jan Seedorf (NEC) presented on Using ICN in Disaster Scenarios (draft-seedorf-icn-disaster/). This is a presentation of the GreenICN project and summarized some research challenges for coping with natural or human-generated, large-scale disasters. Further, the document discusses potential directions for applying Information Centric Networking (ICN) to address these challenges.
All presentations and detailed notes can be found at the ICNRG Wiki.
This summer will host a series of additional ICN events:
Scalable Content Exchange in Challenged ICNs
I presented GreenICN work on Scalable Content Exchange in Challenged ICNs at CCNxCon-2015 this week.

Abstract:
The principles of InformationCentric Networking (ICN), accessing data objects by name (not by location address), securing data objects (not connections), innetwork caching (for sharing, repair, rate adaptation) make ICN attractive for a wide range of application scenarios beyond traditional data center or telco access network scenarios. In fact, one of the first instantiation of ICN had been developed based on DelayTolerant Networking (DTN) technologies.
Currently, ICN/DTN is considered a promising approach for enabling/enhancing communication in disaster scenarios. In such scenarios, socalled ICN data mules (that carry and disseminate data times) may move randomly, and each time data mules encounter one another exchange data items. We envision that in such a scenario where there is no connectivity, data mules (e.g. vehicles or drones) can move around randomly. So these mobile routers interact with end users, working base stations and other data mules to fetch and deliver the data and queries. Thus, we do not consider adhoc networks where you can build a path to the destination reactively or proactively, rather a DTN like scenario.
Consider a large scale disaster scenario like the earthquake in Japan in 2011 , where people in different parts of the city are stranded without the internet connectivity. But there are some zones, where base stations are still working and providing connectivity. Essentially, the scenario is such that ICN data mule move randomly across a geographic area, and when meeting endusers receive interests from them and also forward corresponding data items to endusers (if present in the content store / cache of the data mule). At the same time, when data mules encounter each other, they forward to each other certain enduser interest and/or data items (according to a predefined rule set and algorithm), such that interests and data items can be forwarded in a hopbyhop DTN fashion. One research problem in such a scenario is how to optimize such data exchanges among data mules for optimal data dissemination (e.g. optimizing how many desired messages reach their recipients within a given timeframe with a given forwarding strategy, assuming that data mules only have limited time at each encounter to exchange
messages).
ICN Researchers Meet in Cambridge, MA
The ICN Research Group of the IRTF has met for a two day meeting in Cambridge, MA on January 13/14. More than 30 researchers from the US, Europe, China, and Japan gathered to discuss hot research topics in ICN such as:
- Native ICN-based video streaming
- Security (authenticated denial in ICN)
- IoT and ICN
- Hop-by-hop control messages in CCN
- Named Function Networking
In addition, different groups presented updates on their current implementations and their design decisions for packet formats and ICN protocols. For CCN-based protocols further steps towards a common format have been made.
The next meeting (planned for the week of March 23rd in Dallas, at IETF-92) will continue the packet format discussion and progress new topics such as Named Function Networking.

Call for Papers
** 2nd ACM Conference on Information-Centric Networking (ICN 2015) **
Sponsored by ACM and ACM SIGCOMM
http://conferences.sigcomm.org/acm-icn/2015
San Francisco, USA, September 30 - October 2, 2015
Information Centric Networking (ICN) is a new network architecture intended to provide access to information without requiring an explicit binding of that information to a particular location. By directly addressing information, ICN supports mobile users and mobile networked devices, offers a higher-level communication service to applications, and promotes authentication and efficiency in the transmission and dissemination of information. Over the last few years, a global research and development community has grown around the idea of ICN.

The Beauty of ICN in IoT
One of the papers recenty presented at ICN-2014 described an interesting IoT implementation and corresponding experiment with CCN-Lite on the RIOT platform.
Previously, ICN has been perceived as providing conceptual benefits such as
- simplified, natural APIs to developers;
- increased robustness through caching;
- facilitating data fusion through hop-by-hop replication;
- reduced network stack layering; and
- inherent auto-configuration.
The authors describe their implementation of CCN-Lite on RIOT and their approach to realize IoT communication in a 60 node testbed. The idea is to apply Reactive Optimistic Name-based Routing (RONR), i.e., an ICN name-based forwarding approach to send requests for named information in an IoT network using a hybrid flooding/unicast approach.
Some results of their comparison:
- 70% less ROM, 80% less RAM usage by the stack implementation (compared to a RPL/6lowpan implementation);
- 50% reduction of transmitted packets thanks to RONR and ICN caching.
