Hi cmNOG-ers,

Chers|Chères cmNOG-istes,

Perhaps you know a bit about IPN & DTN, to follow the ongoing research,
in regard, you can subscribe to the ISOC IPN Chapter and join the
relative blog mailinglist.

Peut-être connaissez-vous un peu l’IPN et le DTN? Pour suivre les
recherches en cours, vous pouvez vous abonner au chapitre IPN de l’ISOC
et vous inscrire à la liste de diffusion du blog correspondant.

Below is the first blog, i have just received yesterday.

Trouvez, ci-dessous, le premier blog que j'ai juste reçu hier.

> Note: The blog will be updated weekly on ipnsig.org
> Welcome to the InterPlanetary Networking Blog! We intend to make this
> a weekly publication of interest to everyone interested in
> InterPlanetary Networking (IPN), Delay & Disruption Tolerant
> Networking (DTN), and computer networking in general.
> Since this is the inaugural blog entry, we thought it would be useful
> to back up a bit and answer some basic questions:
> *What is IPN?*
> It is a solution to the constrained network environment present in
> space data communications and, more generally, in the emerging
> Internet of Things.
> TCP/IP, the core technology [BSC(1]
> <file:///C:/Users/msnell/Downloads/2018-11-05%20IPN%20Intro%20Blog.docx#_msocom_1> running
> today’s Internet, assumes essentially instantaneous, continuous
> end-to-end connectivity, and fails when it encounters delay or
> disruption of any significant length (about 4 seconds).
> However, delays and disruptions are inherent in data communications at
> interplanetary distances, with the shortest Round Trip Time (RTT) for
> a radio signal to travel to Mars and back being about 7 minutes. Other
> factors contribute to the network constraints existing in
> interplanetary communications, but delay is the most significant
> factor making existing Internet protocols impractical for use.
>  *Enter DTN:*
> Adrian Hooke (Sr. Technical Director with the Jet Propulsion
> Laboratory, NASA) meets Vint Cerf (co-author of the TCP/IP protocols
> and one of “Fathers of the Internet”) in the late 1990’s. They
> discover they both want to provide the same kind of network
> communications automation in space networking that works so well on
> the Internet.
> Vint Cerf gets to work. A terse history follows:
>   * DARPA funds work at JPL.
>   * Core experimental “delay-tolerant networking” protocols developed
>     by JPL, MITRE, Sparta researchers.
>   * ION implementation of DTN developed at JPL for use by NASA.
>   * DTNRG established to mature the protocols.
>   * ION demonstrated on the EPOXI spacecraft in deep space.
>   * ION deployed for all science payload communications on ISS.
> *Where is IPN today?*
>   * IETF DTN Working Group formed to establish DTN protocols as
>     Internet standards.
>   * Consultative Committee for Space Data Systems (CCSDS—a global
>     standards setting organization for civilian space flight)
>     standards adoption well underway.
>   * Security Protocols maturing (including Public Key Infrastructure—PKI).
>   * Dr. Scott Pace (White House Space Policy Director) challenges NASA
>     to use DTN for all space communications (see
>     https://www.youtube.com/watch?v=InMP-OI1thw&index=9&list=PL4buVHalBRoPpFRFlpYVnXHLwWNwFmpmt&t=0sfor
>     Dr. Pace’s presentation at our 2015 IPN Speakers Conference).
>   * NASA integrating DTN into ground networks and future spacecraft.
> *IPN's bright future*
>   * Increasing standardization amongst civilian space agencies.
>   * Increasing international research into DTN for constrained
>     terrestrial as well as space networking environments.
>   * Coming adoption as internet standards.
> *What’s next for the blog?*
> Each week, we will post news about the exciting world of IPN, or
> summaries of academic research, or links to IPN in the mainstream
> media. We’ll also be announcing upcoming IPNSIG events and activities.
> We hope you enjoy the blog.
> This blog is a product of the usual suspects: Scott Burleigh
> (NASA/JPL); Jay Wyatt (NASA/JPL); Keith Scott (Mitre Corp./CCSDS) and
> Mike Snell (IPNSIG)
