The need for new DC architecture has been the subject of research for
quite sometime.
I recall that Prof. Brighten (UCIC) had a paper on spineless DC in
HotNet 2021 [Spineless Data Centers (acm.org)
<https://dl.acm.org/doi/pdf/10.1145/3422604.3425945>]. He presented it
in ONUG research track in 2021 [the recording is available here:
Spinelessness: The Future of Data Center Networks? - ONUG | ONUG
<https://onug.net/events/spinelessness-the-future-of-data-center-networks/>
The abstract of the ONUG talk:
"/Leaf-spine and Clos network topologies have become ubiquitous in
modern data centers to achieve high throughput for data-intensive
applications. In fact, such designs are not optimal: recent research
has developed other topologies, specifically expander graphs, that
achieve higher throughput or lower cost, along with potentially easier
incremental expansion. In this talk we’ll explore whether this
theoretical performance efficiency can be realized in a practical way to
improve enterprise leaf-spine data centers. This leads to a “spineless”
data center, with a single type of switch rather than having separate
roles for leafs and spines. We find that such designs can indeed be
more efficient even at small to moderate scale, and we introduce an
efficient routing scheme for such networks that uses standard hardware
and protocols. This line of work opens new research directions in
topology and routing design that can have significant impact for the
most common data centers/."

We used the webex provided by IETF during the side meeting, and the
Webex on Jeff's laptop crashed at the end of the meeting. We were told
that the recording might be on the IETF chromebook, but haven't heard
anything yet.
Meanwhile you can have access to all the slides including the ones
that didn't get time to present at: Yingzhen-ietf/AIDC-IETF117: This
repository is for all the meeting materials. (github.com)

Hi Yingzhen,
Do we have any recording for this meeting?
Thanks,
