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

NFD: Issue Your Own NDN Certificates

[This post is a repost from https://yoursunny.com/t/2016/ndncert/ written by NDN developer Junxiao Shi]

To publish contents into a Named Data Networking (NDN) backbone network, you need to connect your NFD end host to the NDN Testbed, run a local producer application, and let the world reach your NFD through Automatic Prefix Propagation. However, a limitation with NDN Forwarding Daemon (NFD)’s Automatic Prefix Propagation is that, the prefix registered toward your end host is always the identity name of your certificate. While this works fine when you only have one or two machines, two problems arise when you want to deploy multiple end hosts:

  • Every certificate request needs an email verification and manual approval process, which is inconvenient. Or, you can copy your certificate and private key onto every machine, but in case any of these machines is compromised, your one and only private key will be exposed.
  • Certificates requested with the same email address have the same “identity name” and hence Automatic Prefix Propagation would register the same prefix. Unless all your machines serve the same contents, registering the same prefix toward all machines hurts network performance because the router has to rely on flooding and probing to figure out which of your machines serves a certain piece of content.

Let the World Reach Your NFD

[This post is a repost from https://yoursunny.com/t/2016/nfd-prefix/ written by NDN developer Junxiao Shi]

Named Data Networking (NDN) is a potential future Internet architecture designed as a distribution network. My last post on yoursunny.com described how to connect an end host running NDN Forwarding Daemon (NFD) to the NDN Testbed, a backbone NDN network for research purposes, and retrieve contents from that network. An equally important topic is: how can you publish contents into the backbone network?

As mentioned in the last post, NDN communication is receiver driven. Interests expressed by the consumer application are forwarded toward the producer following the routing table, and Data packets carrying contents flow back on the reverse path of Interests. Every end host and router along the path between consumer and producer needs to have a route in its routing table, so that NFD can forward the Interest, hop by hop, toward the producer. On your own machine, nfdc register command adds a route to the routing table; however, if you want to publish contents into the backbone network and make them available for others to retrieve, you won’t be able to directly execute nfdc register command on a terminal of the routers. How can you add a route without console access?
