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

  • We will host our next NDNcomm at the University of Memphis March 23-24, 2017 immediately preceding IETF 98 in Chicago. We will hold the 4th NDN Hackathon immediately following NDNcomm on 25-26 March, 2017. You can find details regarding the meeting, travel grants, and accommodations at http://www.caida.org/workshops/ndn/1703/
  • Coming up in December 2016, adjacent to IEEE Globecom 2016 at the Workshop on Information Centric Networking Solutions for Real World Applications (ICNSRA 2016) in Washington D.C., the NDN team will present a publication (listed below) as well as participate on a panel discussing “Application of ICN in Infrastructure-Free Environments: Rural Areas, Disaster Recovery, and Military Tactical Environments. See more details at http://icnsra.nz.comm.waseda.ac.jp/?page_id=61
  • On the heels of our recent NDN Retreat, we held the 3rd Named Data Networking (NDN) Hackathon November 4-5th, Colorado State University, Fort Collins, CO. See which projects took home the coveted Quadcopter Mini Drones at http://3rd-ndn-hackathon.named-data.net/.

  • 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/.
