ICNRG Documents and Presentation Material


Informational RFCs

  • RFC 7476 Information-Centric Networking: Baseline Scenarios (was draft-irtf-icnrg-scenarios)
    • A document that defines reference baseline scenarios to enable performance comparisons between different approaches.
  • RFC 7927 Information-Centric Networking (ICN) Research Challenges (was draft-icnrg-challenges)
    • 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.
  • RFC 7933 Adaptive Video Streaming over ICN (was draft-irtf-icrng-videostreaming)
    • A document that describes key issues of video streaming in ICN and considers how the current video streaming should be modified in an ICN architecture.
  • RFC 7945 "Information-Centric Networking: Evaluation and Security Considerations" (was draft-irtf-icnrg-evaluation-methodology)
    • This document presents a number of considerations regarding evaluating Information-Centric Networking (ICN) and sheds some light on the impact of ICN on network security. It also surveys the evaluation tools currently available to researchers in the ICN area and provides suggestions regarding methodology and metrics.

Experimental RFCs

  • RFC 8569 "Content-Centric Networking (CCNx) Semantics "
    • This document describes the core concepts of the Content-Centric Networking (CCNx) architecture and presents a network protocol based on two messages: Interests and Content Objects.
  • RFC 8609 " Content-Centric Networking (CCNx) Messages in TLV Format "
    • This document specifies the encoding of CCNx messages in a TLV packet format, including the TLV types used by each message element and the encoding of each value.

Upcoming ICNRG events

ICNRG online Interim meeting on April 20th 2020

As you have probably noticed, the IETF-107 in-person has been cancelled (, which affects all WG, RG, and side meetings.

ICNRG will have an online meeting on April 20th, 2020 instead.

There are certain activities that could progress in the meantime and that do not necessarily require time in a virtual meeting, for example describing and discussing Draft updates — so we encourage you to use the mailing list more.

Also, the Internet Draft submission system should be opened again, so please use that opportunity if you have unsubmitted work.
