Tunnel Ethernet Traffic Over NDN

[This post is a repost from https://yoursunny.com/t/2017/tunnel-Ethernet-over-NDN/ written by NDN developer Junxiao Shi]

Named Data Networking (NDN) is a common network protocol for all applications and network environment. NDN’s network layer protocol runs on top of a best-effort packet delivery service, which includes physical channels such as Ethernet wires, and logical connections such as UDP or TCP tunnels over the existing Internet. Using this underlying connectivity, NDN provides a content retrieval service, which allows applications to fetch uniquely named “Data packets” each carrying a piece of data. The “data” could be practically anything: text file chunks, video frames, temperature sensor readings … they are all data. Likewise, a packet in a lower layer network protocol, such as an Ethernet frame, is also a piece of data. Therefore, it should be possible to encapsulate Ethernet traffic into NDN Data packets, and establish a Virtual Private Network (VPN) through NDN communication. This post describes the architecture of a proof-of-concept Ethernet-over-NDN tunneling program, and shows a simple performance benchmark over the real world Internet.

The Program

tap-tunnel creates an Ethernet tunnel between two nodes using NDN communication. Each node runs an instance of tap-tunnel.
This program collects packets sent into a TAP interface, and turn them into NDN packets. It then gains NDN connectivity by connecting to the local NDN Forwarding Daemon (NFD). The diagram below shows the overall architecture: Read More

Community Outreach

  • On 20-23 March 2016 we held the 2nd NDN Hackathon and Project Retreat. We welcomed over 30 participants for the Hackathon and over 50 for the Retreat to the University of California at San Diego campus in La Jolla, CA. The retreat focused on science applications, technical discussions with a focus on NFD development, autoconfiguration IoT over NDN, and architectural principles and future collaboration and funding opportunities. For final agenda, slides, and breakout outcomes see the web page at www.caida.org/workshops/ndn/1603/. For the final list of projects and links to code from the Hackathon, see http://2nd-ndn-hackathon.named-data.net/.

NDN Project Monthly Newsletter for August 2015

The NDN project team compiles and publishes this newsletter monthly to inform the community about recent activities, technical news, meetings, publications, presentations, code releases, and upcoming events. You can find these newsletters posted on the Named Data Networking Project blog.

Community Outreach

  • Plans and agenda continue to firm up for the NDN Community Meeting (NDNcomm 2015) to be held at the University of California at Los Angeles campus in the Little Theater, MacGowan Hall, UCLA on 28-29 September 2015. Those interested are still invited to register for NDNcomm 2015, but we will likely be unable to support further requests to present.
  • Hackathon: 26-27 September 2015. We are excited to announce the first NDN hackathon scheduled prior to the upcoming NDNcomm 2015. The organizers welcome participants across all experience levels and are reaching out to the community for project suggestions. If you have an idea for a project, please see the Call for Projects and email Steve DiBenedetto (dibenede@cs.colostate.edu).

    Project representatives will pitch their ideas to hackathon attendees and act as guides/mentors. We also plan projects suitable for NDN newcomers. Please stay refer to the NDNcomm 2015 Hackathon Participant Guide. We hope to see you in LA!

Technical News

  • The NDN Testbed added two new nodes at Verisign and the Korea Institute of Science and Technology Information to bring the total to 26 nodes. Currently we have nodes in 9 different countries. You can see the current status of the testbed and the real time bandwidth usage online.
  • We announced the release of version 0.2.1 of Named Data Link State Routing Protocol (NLSR). Detailed release notes and more information about NLSR, tutorials, installation and configuration guides, and other useful resources are available on the official webpage of NLSR.

NDN Publications, Presentations, and Technical Reports

  • In June, we posted the NDN Next Phase project annual report. This report catalogs a wide range of our accomplishments during the first year of the NDN Next Phase (NDN-NP) project. This phase of the project is environment-driven, in that we are focusing on deploying and evaluating the NDN architecture in two specific environments: building automation management systems and mobile health, together with a cluster of multimedia collaboration tools.
  • NDN TR-30 Revision 2: Yingdi Yu, Alexander Afanasyev, David Clark, kc claffy, Van Jacobson, and Lixia Zhang. “Schematizing and Automating Trust in Named Data Networking” that describes how NDN automates data authentication into the narrow waist layer using trust schemas.

Additionally, a group from Imperial College London presented “Possibilities for Named Data Networking in HEP” whereby they built the NDN platform on Centos7 and built a custom C++ application to provide repository services (“repose”). The application is built against lib-ndncxx to connect it to NDN and to backend filesystem libraries librados (part of Ceph) & libcurl The backends serve files into the NDN namespace from either a conventional POSIX filesystem, Ceph or HTTP source (currently read-only client pending solution for authentication).
