Hi !
Yes, the commons model is superior. CNs need to learn how to make their
implementations work on a millions scale.
At B4RN they say they give the best connectivity
in the UK because they
dedicate all their resources to that, and they don't have to pay others.
That is what is needed to build an independant community network. Basing
a Community Network on a 100 Mbps or a GBPS or two from an ISP or a Telecom
company makes it a good start, but the Network is an effect a
sub-distribution operation for a Telecom / ISP in terms of its dependance.
I agree, there are communities that have started like that. Sharing a
transit connection is a good way to reduce the entry barrier. One good case
is RemIX in Scotland:

The above link is broken, and also the link to remix architecture from the
page

The ec website has a brief article on remix, featuring a link to the remix
architecture pdf, which also leads to a page that shows the link broken
(screenshot attached). However an earlier ec blog post on remix led me to
hubs net, and from its member pages -- > tegola net how to pages, I landed
on the specification for P2P and edge equipments, and found some
interesting information such as on

Thank you.
Several community networks, as they grow, aggregate
more traffic, buy more
capacity from different carriers, get connected
to IXPs (e.g. Ninux,
Freifunk, guifi, B4RN ... cases we have studied in Europe) which allow them
to exchange traffic with many other networks, which results in better
quality traffic for everyone involved.
In the case of
guifi.net they also rent optical regional circuits thanks
to its cost-sharing model to aggregate capacity (the
sub-distribute/aggregate traffic you mention) from multiple individual or
local participating retail ISPs that are part of
guifi.net. Therefore
they bridge the gap from retail capacity required by participants to
wholesale open-access fiber networks.
All these are good examples to follow. The goals of good community
networks such as guifi.net's goal of "promoting advanced research in the
filed of open networks and infrastructures, and that of generating
collaboration platforms between stakeholders" worth expanded attention.
There could be a concerted effort for advanced research, and there could be
a globally unified platform for collaboration on Community Networks. The
Internet Society could help build one, using voluteer effort and open
source technologies.
Just to understand, do submarine networks offer
commercial arrangements
for transport on a minimal scale ( 1GB / 10 GBPS )?
I'd say this is the role of global carriers and top tier ISPs that offer
these rates in many points-of-presence globally.
Submarine networks that are at a higher scale of
aggregation.
It would be helpful to understand what this 'higher scale' is (For
example, See-Me-We 4 has a design capacity of 4.6 TBPS / s . Would it be
too insignificant for this network to provide a strand of 100 GBPS/s ? for
we will eventually get there, and surpass this scale (one or two new
Community Networks with higher aspirations could even start at the beach
front)
What is the typical cost of a 1GB / 10 GBPS switch at an IXP? Do IXPs
