NDN-NP Project 2014-2015 Annual Report

June 29, 2015 by CAIDA in Updates | Comments Off on NDN-NP Project 2014-2015 Annual Report

We recently published our annual report covering our activities from May 2014 through April 2015. We excerpt the executive summary here, for the entire report see http://named-data.net/wp-content/uploads/2015/06/ndn-ar2015.pdf:

The heart of the current Internet architecture is a simple, universal network layer (IP) which implements all the functionality necessary for global interconnectivity. This thin waist was the key enabler of the Internet’s explosive growth, but its design choice of naming communication endpoints is also the cause of many of today’s persistently unsolved problems. NDN retains the Internet’s hourglass architecture but evolves the thin waist to enable the creation of completely general distribution networks. The core element of this evolution is removing the restriction that packets can only name communication endpoints. As far as the network is concerned, the name in an NDN packet can name anything — an endpoint, a data chunk in a movie or a book, a command to turn on some lights, etc. This conceptually simple change allows NDN networks to use almost all of the Internet’s well-tested engineering properties to solve not only communication problems but also digital distribution and control problems.

Our first four years of NDN design and development efforts (which has a 4-month overlap with NDN-NP) tackled the challenge of turning this vision into an architectural framework capable of solving real problems. Our application-driven architecture development efforts force us to fill in architectural details, and most importantly, verify and shape the architectural direction. We translated our vision to a simple and elegant packet format design, a modular and extensible NDN forwarding daemon, and a set of libraries, including security support, to support application development. These achievements establish a platform that enabled us to tackle new application environments as we stated in the NDN-NP proposal: open mobile health applications, building automation and management systems, and multimedia applications. We achieved all our major milestones for the first year of the NDN-NP project. Highlights include:

Get NFD Connected

January 6, 2015 by CAIDA in Updates | Comments Off on Get NFD Connected

The Named Data Networking (NDN) Project offers a potential future Internet architecture designed as a distribution network.

The last post described how to deploy the NDN Forwarding Daemon (NFD) on a low-end box. This post describes how to get it connected.

The procedures and experiences in this post apply to any NDN node. If you aren’t using a low-end box, you may follow the official guide to install binary packages or compile from source. This post assumes you have ndn-cxx, nfd, and ndn-tlv-ping installed. You need access to two machines with NFD running; referred to as “local” and “remote”.

Connect to Another Machine

After installing NFD on your machine, you can connect to any other machine running NFD. Although NDN can run natively above Ethernet, there isn’t a global scale native NDN network yet because NDN is still in its early stage. Instead, NDN can run as an overlay network on top of a traditional IP network. You can specify the IP address and port number of the remote NFD, so that NDN packets get encapsulated into UDP or TCP packets and sent to the remote NFD.

To establish a connection, enter the following command:

How to Deploy the NDN Forwarding Daemon on a Low-End Box

September 26, 2014 by CAIDA in Updates | Comments Off on How to Deploy the NDN Forwarding Daemon on a Low-End Box

Named Data Networking (NDN) is a potential future Internet architecture designed as a distribution network. To access the NDN network from a Linux or Apple OSX machine, one can install the NDN Platform, a collection of software packages including the protocol stack and critical applications. The NDN Forwarding Daemon (NFD), a core component of the architecture, serves as a software router and runs both on the network routers as well as on end hosts to communicate with routers.

The NDN team provides periodic releases of the new platform, and binary packages are provided with each platform release. However, the development of NDN software, including NFD, happens much faster than platform releases, so users can download source code from GitHub. If a user wants to run bleeding edge software, those packages must be built from source code.

As a geeky low end box user, I’m thinking: can I run the NDN platform on a Linux box with only a small amount of memory? The box I’m talking about is an OpenVZ container from LowEndSpirit UK location, with only 128MB memory and no swap space. To make the challenge more interesting, I want to avoid apt-get, and run the bleeding edge version built from source code.

NDN Project 2012-2013 Annual Report

October 17, 2013 by CAIDA in Updates | Comments Off on NDN Project 2012-2013 Annual Report

We finally published our annual report covering our activities from Sept 2012 through August 2013.  We excerpt the executive summary here, for the entire report see http://named-data.net/wp-content/uploads/2013/10/ndn-annualreport2012-2013.pdf:

Today’s Internet’s hourglass architecture centers on a universal network layer (i.e., IP) which implements the minimal functionality necessary for global interconnectivity. This thin waist enabled the Internet’s
explosive growth by allowing both lower and upper layer technologies to innovate independently. However, IP was designed to create a communication network, where packets named only communication endpoints. Sustained growth in e-commerce, digital media, social networking, and smartphone applications has led to dominant use of the Internet as a distribution network. Distribution networks are fundamentally more general than communication networks, and solving distribution problems via a point-to-point communication protocol is complex and error-prone.

The NDN project proposes an evolution of the IP architecture that generalizes the role of this thin waist, such that packets can name objects other than communication endpoints. The name in an NDN packet can be anything — an endpoint, a data chunk in a movie or a book, a command to turn on some lights, etc. This conceptually simple change allows NDN networks to use almost all of the Internet’s well-tested engineering properties to solve not only end-to-end communication problems but also content distribution and control problems. Based on three decades of experience with the strengths and limitations of the current Internet architecture, the design also builds in fundamental security primitives (via signatures on all named data) and self-regulation of network traffic (via flow balance between Interest and Data packets). We recognize that any new architecture must be incrementally deployable over the current Internet, and we explicitly consider factors that will facilitate user choice and competition as the network evolves.
