Hi Siva –
We have a programme – a pretty major one where we are supporting CNs.
In fact, we work closely with APC, Guifi, governments and many more actors.
I really think you should ping Naveed about the training in Delhi in October.
Naveed is cc’d.
Best,
Jane

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:
http://www.cs.stir.ac.uk/~mmf/res/pubs/gaia16_remix.pdf
The above link is broken, and also the link to remix architecture from the page
https://ec.europa.eu/digital-single-market/en/news/good-practice-remix-dist…
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
https://dl.ubnt.com/datasheets/airfiber/airFiber_5XHD_DS.pdf If you have a copy of the
remix architecture pdf, please share the file.
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 everywhere offer
supernodes to Community Networks?
CNs can participate in IXPs just like any other member org. The price of ports in IXP I
understand depend on the size and specific infra costs of that IXP (size is really
diverse). Many IXPs are also distributed (PoP in multiple locations). These are from our
local IXP:
http://www.catnix.net/en/taxes/
In addition, the transport/peering costs in the IXP vary depending on the symmetry of
traffic. For instance, I remember talking to Freifunk in Berlin 1-2 years ago, and they
were paying net 0 for traffic (without entering into details) as they have a very
symmetric traffic (a good balance between content they deliver and they request, the so
called "eyeballs").
Would be helpful if any of the submarine networks or its partners and IXPs share their
pricing roughly.
Many of these prices can be collected or guessed from diverse sources. If you investigate
that it would be useful to share the results.
Kind regards, Leandro.

They're not the only ones. In
https://www.measurementlab.net/publications/2015-Braem-et-al.pdf with independent data
from M-Lab, you can see that 3 CNs are among the best operators in their countries in
quality (e.g. section 4.2 pg 5, Figure 10 pg 6). We say: "The three networks are
among the top eight ISPs in download speed.
guifi.net is ranked first in Spain both in
median upload speed and best median latency; Ninux (FusoLab) is ranked second in upload,
and fourth in best latency; AWMN (part of LANCOM) is first in upload speed, 8th in best
latency. In the area of Barcelona, where
guifi.net has its connections to Internet
carriers, the results are excellent: first in upload speed (
guifi.net 7.82 Mbps, the
Academic network 4.23 and Cableuropa ONO 3.31), third in download speed (Cableuropa-ONO
18.1 Mbps, the Academic network 9.8,
guifi.net 9.79) and first in best latency (
guifi.net
14 ms, Vodafone 25, Cableuropa-ONO 35)".
That is something known in the world of free software. There are free implementations that
are superior to commercial ones (Android is based on GNU/Linux, let's see when
Movistar is based on the infrastructure of
guifi.net...). All commercial software products
are built from free software, built openly and cooperatively (as commons), because that
seems to be the only way to have robust enough software infrastructures/libraries at a
reasonable cost/quality to build stable products on top.
Cheers, Leandro.

Hi Sivasubramanian,
Community networks does exist in India and it is a sustainable initiative.
Gram Marg at IIT Bombay has set up one spanning 10 villages in Palghar,
Maharashtra, Digital Empowerment Foundation has set up some as well. There
are more going to be set up in this year and the next. These CNs are set
up in locations that have no mobile connectivity and are usually in
remote, rural villages of India.
Local ISPs have come to the rescue and provide bandwidth in such locations.
With regards,
Sarbani
In Chennai, India, I spoke to someone in an educational institution about
starting a Community Network. He argued that access is no longer a problem
as Telecom companies offer 3G and 4G services everywhere. He wouldn't
listen to arguments concerning the cost and clever pricing models of
access
that indiscernably amass huge sums by microscopic extraction, wouldn't
listen to arguments about nominal and actual bandwidth. He and some
others
take the position that a case does not exist for Community Networks here.
Happens to be an iconic opinion. It is a challenge to present arguments,
articles such as this are of ample help.
