Below is a list of the current IETF 94 Hackathon technical topics. Don’t see anything that interests you? Feel free to add your preferred technology to the list, sign up as its champion and show up to work on it. Note: you must login to the wiki to add content. If you do add a new technology, we strongly suggest that you send email to to let others know. You may generate interest in your technology, and find other people who want to contribute to it.

Technologies Included in Hackathon (more can be added)

DHCP 4o6



  • Champions
    • Susan Hares
    • I2RS RIB - add/delete v4 routes
    • I2RS Topology add/delete L3 node, and link
    • I2RS FB-RIB - add/delete one filter for v4 route
    • participants: TBD
    • software: ODL based


NETCONF/YANG, I2RS, OpenDaylight

  • Mahesh Jethanandani (Sunday), Carl Moberg (arrive Sat Mid day): searchable YANG directory, e.g. front-end to be a RESTCONF-server with a known YANG Model to query for URLs based on namespace-URNs
  • Jan Medved (virtual attendance): YANG model dependency visualization tool
  • ? : extract URI and revision number from RFC
  • Anees Shaikh: a few pyang plugins, including one to help relocate modules into a larger structure
  • Benoit Claise: improve the YANG stats on, flagging some specific error messages, improving the visual, including IEEE stats
  • Champions:



IBNEMO(Intent Based Network Modeling)

  • NEMO Language is an Intent oriented network DSL (domain specific language) and NBI. Operator/End-user or 3rd party can use it to program network resource and behavior in their service applications. It's now being implemented in Opendaylight (
  • Goals
    • Come up with an initial toolset to produce and manipulate NEMO
    • Implement the use cases as a proof of concept for NEMO
  • Tasks
    • set up the integration environment
    • develop applications to use the NEMO API
    • develop an Eclipse based NEMO editor
    • develop other useful tools
  • Possible use cases
    • end to end carrier network including vCPE
    • virtual private cloud integrating NetIDE
  • Prerequisites
    • Editor
      • Eclipse MARS with modeling tools
      • Xtext
    • Controller
      • OpenDaylight (see reference)
      • Mininet (VMs will be provided)
  • Champions


  • DNS64 for Homenet use (stand-alone daemon? existing? add to dnsmasq? add to many options)
  • NAT64 for Homenet use (fix existing one to fit the requirements? write new PLAT in Linux kernel?)
  • Start/Work on DNCP/HNCP conformance test suite
  • Implement more tests for HNCP
  • Improve quality of (OpenWrt) hnetd by installing it + playing with it (bring your own supported router; see )
  • Champions

RIOT (OS for internet of things)

  • Tasks
    • Take the excellent TSCH implementation of the OpenWSN project and introduce it as a MAC protocol to RIOT.
    • Updating the CCN-Lite stack in RIOT, work on a flexible transport implementation. The goal is to make it configurable whether CCN runs over UDP or directly over any link-layer (Ethernet, IEEE 802.15.4…)
  • Champions
  • Setting things up

Participant Preparation and Prerequisites

  • Bring a laptop on which you are comfortable developing software
    • Some projects may require installing additional software
  • Familiarity with the technology area(s) in which you plan to participate will certainly help
  • Brief introductions will be provided at the start of the Hackathon by the champions associated with each technology
  • Your laptop is the default development platform for each technology
  • Anything else that is required will be provided, such as VMs you can install on our laptop or access from your laptop
    • Installing and becoming familiar with VirtualBox or something similar will help
    • Note to champions: if planning to make use of VMs, please bring on USB drives to may available to others as download times can be painful
  • Specific coding languages are called out for some of projects (e.g. Python, Java), but this is heavily dependent on the project(s) you choose
  • Wireless access to the IETF network will be provided, and from there to the outside world
  • Git/GitHub is commonly used for open source projects. Familiarizing yourself with it is recommended.
  • Champions for each technology are encouraged to share any other things they think would be helpful in preparation for the hackathon

IPR and Code Contribution Guideline

All hackathon participants are free to work on any code. The rules regarding that code are what each participant's organization and/or open source project says they are. The code itself is not an IETF Contribution. However, discussions, presentations, demos, etc., during the hackathon are IETF Contributions (similar to Contributions made in working group meetings). Thus, the usual IETF policies apply to these Contributions, including copyright, license, and IPR disclosure rules.

Recap and Results

Project Presentations

  • DHCPv4o6 “Best Interop”
  • IBNEMO “Best Video Demo”
  • NETCONF (YANG) “Best Tool”
  • NETVC “Best Continuous Improvement”
  • RIOT “Best Future Internet Component”
  • SFC “Best Enabler for New Network Functions”

Top three

  • HOMENET “Best of Show”
  • I2RS “Most Helpful Failure”
  • DNS “Best Internet Security Improvement”
