12th NDN Retreat and 10th NDN Hackathon (Postponed until further notice)

Important announcement:
Due to the concern of COVID-19 virus, we have decided to postpone the NDN project retreat out of precaution until further notice.

There will be no project retreat next week as originally scheduled. The new date is tentatively set to May 14 and 15, and Hackathon on 16 and 17. We will reevaluate the situation in a month or so.

The 10th NDN Hackathon will be held on 14-15 March, 2020 in the University of Arizona, Tucson, Arizona. The hackathon projects are intended to advance the current state of NDN. Participants will have approximately 12 hours to work on their projects. Remote participation is welcome!

Named Data Networking Community Meeting (NDNcomm) 2019

Venue: National Institute of Standards and Technology (NIST), Gaithersburg, MD, USA

Dates: September 5-6, 2019

More details on NDN Community Meeting 2019

Named Data Networking Community Meeting 2019 will be hosted by the National Institute of Standards and Technology (NIST) on September 5 and 6, 2019. The organizing committee cordially invites you to participate in and contribute to the event!

NDNComm is an annual event that brings together a large community of researchers from academia, industry, and government, as well as users and other parties interested in the development of Named Data Networking (NDN) technology. NDN is an architectural realization of the broad Information Centric Networking (ICN) vision that enables communications by named, secured data at the network layer. By aligning the network service with application needs, NDN offers many advantages, including stronger security and trustworthiness, enhanced network usability, as well as scalability and resiliency in network communication. In particular, NDN is especially suitable for emerging network environments such as edge computing and Internet of Things (IoT).

IEEE International Conference on Communications – (RAFNET 2019)

6th International Workshop on Research Advancements in Future Networking Technologies

Recently, a lot of research efforts have been made by both academia and industry side to promote various new and emerging network paradigms. The reason is that during the past decade, it has been realized that the current internet architecture was originally designed for end-to-end host centric communications, however, the actual focal of communications is the content itself. Hence, we have witnessed new architectures such as an Information-Centric Network (ICN) with various extensions like Content-Centric Network (CCN), Named Data Network (NDN), Data-Oriented Network Architecture, and so on. On the other hand, enormous efforts in cellular networks have been made for improving the user experience and as a result, today, we are able to use LTE-A and other networks. In this context, the upcoming 5G networking architectures, whose ongoing research is focused on the networking mechanisms regarding the massive increase in the number of connected devices, bandwidth requirements, reduced latency, and the deployment of supporting operational mechanisms such as network virtualization, cloud-based deployments, mobile edge computing, and storage and new utilization scenarios. Moreover, these modern technologies are being applied in other networking domains as well, including VANETs, Smart Grid, Smart Cities, Internet of Things, Big Data, etc.

The 6th RAFNET workshop was in Shanghai, China on May 24, 2019. The workshop had a panel discussion on the topic “ICN coming out of age” with members from the NDN Project team being the panelists. The workshop also had several NDN papers presented. The papers and presentations will be added shortly to this website.

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
