[Nfd-dev] NDN-Lite on Contiki NG

[Junxiao Shi]

Hi Alper

The NDN-Lite codebase appears to have been abandoned, as it has not been
updated since 2021.
It is not interoperable with any other NDN codebase due to the usage of a
different fragmentation protocol (see
https://redmine.named-data.net/issues/4814 ).
It also lacks a data synchronization protocol such as StateVectorSync,
which is believed to be an essential functionality needed by many NDN
applications.

Moreover, NDN-Lite has been moving away from its roots in small IoT devices.
The ndn-iot-package-over-nordic-sdk
<https://github.com/named-data-iot/ndn-iot-package-over-nordic-sdk> repository,
last updated in 2019, is the only port of NDN-Lite that can run on a
microcontroller.
New additions in the main NDN-Lite repository have not been tested on a
microcontroller, and I have noticed that they may consume a
substantial amount of RAM.

Therefore, I believe that trying to port NDN-Lite to another platform would
be wasted effort, unless the above issues are addressed first.

Nowadays most of the new developments are in ndnd
<https://github.com/named-data/ndnd>, a codebase written in Go.
It is interoperable with most other NDN systems and supports recent
protocols like StateVectorSync and LightVecSec.
Using the TinyGo compiler, a Go program may be compiled to run on dozens of
microcontrollers.
If you are interested in running NDN applications in IoT devices, I'd
suggest trying to compile portions of ndnd with the TinyGo compiler.

Yours, Junxiao
