GNA Reference Documents v1.0 – January 2017

The GNA Technical Working Group produced six documents that together are the Global Network Architecture Reference v1.0. These documents were published in January 2017:

The conformance with PDF/UA ensures accessibility for people with disabilities who use assistive technology such as screen readers, screen magnifiers, joysticks and other technologies to navigate and read electronic content.

Animation of a GNA Compliant Network Infrastructure for R & E – Artist’s Impression

While the process of making an inventory of GNA Compliant Network Infrastructure for R&E has started, an animation has been created that puts an artist’s impression time perspective to this work. Please note that this is draft and work in progress, and no rights can be derived from this. It is provided as is. Suggestions are welcome to the address of the GNA Technical WG co-chairs.


GNA Compliant Infrastructure

While the above artist’s impression of the GNA shows what could be achieved, work started at the end of 2016 to see which parts of the current (and shortly upcoming) R&E network infrastructure is compliant, by means of self-assessment  of the owner of the resource, with the GNA Reference Documents v1.0. At the Internet2 Global Summit in Washington, DC, in April 2017, the Phase I of the GNA Compliant Infrastructure was presented, and looks as follows:

  • The GNA v1.0 compliant GXPs (click on image to enlarge):

  • The GNA v1.0 compliant links (click on image to enlarge):

Check lists for self assessment against the GNA Reference Architecture v1.0 by resource owners are available here:

The GNA MaDDashes

Both KDDI and Internet2 have started a monitoring effort on the GNA Compliant infrastructure for Research and Education, in the form of a reachability matrix using MaDDashes:

It is the intent that both MaDDashes will be merged into one. KDDI has kindly offered to be the host of this. More soon.
