 Hello. Thank you so much for coming to this presentation. We are very happy to see so many people here. So Ivan, we are both from EXO, which is an association related to GiffyNet. And well, we'll give an overview of what Giffy is, its relationship to free software. That's an overview. So, this presentation is mainly based on this document, which is what is GiffyNet's introduction to GiffyNet wrote by Roger Puello. You can easily, very easily find it on the main GiffyNet page. So, it's to be acknowledged for that. So, there are many misunderstandings on what Giffy is, so I will start by telling what GiffyNet is not. GiffyNet is not an internet provider. It's not an ISP. But we use the access to the internet. We can use this kind of access. It's not a subscription service, but there are many companies and organizations that provide this service on top of GiffyNet. It is not a second-class network, some hobbies network. It is connected to the core infrastructure of the internet. It is not just a Wi-Fi network. We are using more advanced technologies like optical fiber right now. And for many years we've been doing this. It is not a single corporation of any kind. It's not a public or private corporation. There are many corporations, many organizations that are part of GiffyNet or participate in it. It is not something held by a single organization as well. GiffyNet itself, as a network in this aspect, has many, many owners. And it is not some kind of very radical movement trying to change the world and make it burn. We are transformative with, let's say, political, may say in the broad sense, political movement. But we are not very radical in the sense. And we are not a geek-only or hobbyist-only project. There are many kinds of roles. Everyone can participate. Everyone can play their role. We are not some wild west place at all. We have very clear rules that we will introduce to you later. And it is not actually a new idea. This is an application of the common pool resource handling to something that is new, like computer networks. This also happens with free software. So it's just a new version of something very old. I will explain a little bit of the technological project of GiffyNet. Before I talk about techy stuff, let's see a little bit of context. GiffyNet started in a little area in the countryside of Spain and Catalonia, named Ozone. There are almost no broadband internet access. So nature started to collaborate and self-provision their internet access. They were not geeky people. They are farmers, normal people that wanted to access that public resource. As Ivan said, it's a common pool resource like some other resources like free software. It has some fundamental conditions that it's free. Anyone can do anything like hosting hp.net web pages. You are free to do anything. It's open to anyone. So you can join and study the network, see how it works and improve it. And it's neutral. So there is no discrimination on the content or who you are to access the network. It started from using community Wi-Fi hardware, like the Lensys BWLRT. In 2008, it became an autonomous system and joined the Katniks Internet Exchange in Barcelona, where we exchanged traffic with other ISPs and connected to some top-level providers. In 2010, there were more than 10,000 mothers and we started to deploy optical links. Nowadays, there are more than 33,000 nodes and almost 50,000 projects. During the questions, we will show you a little video of the growth of the network. Here you can see a map of the nodes that are actually on the network. About the infrastructure that we run on, we have a Drupal website where anyone can register and post their node configuration. We use OpenLDAP for authentication, both on the website and the network resources, like Internet Proxies. We use some tools like Smokeping, Weathermap or GSTOIP for managing resources related to the network operation center in the Katniks. For config management of the network protocols, we use Beard, Quagga and BMIX6. It's a mesh routing algorithm. We use SNMP as protocol, both by CACTI and some Drupal modules that we have developed to publish the usage information. Almost all routers on Gifinette run on Genealynx firmware, although there are a lot of closed source systems that we are trying to change. It's what users mainly use from MikroTik and other platforms. We have some supporting services for the users to collaborate like Simpa for the Miling List, Rocket Chat that is widely used to communicate among users and EtherPAT and MediaDrop for video publication. There are a lot of self-developed projects that started with the needs of Gifinette. As I said before, there are some primordial Drupal modules that let users create domain names and associate to resources. This information is replied to all the DNS servers of the network that are geographically distributed among the different geographical areas. Also, there is a package that is named an SNP service that those of the SNP collecting and services as a RD tool images to the web page. Also, we have developed a main routing firmware that is used a lot in the network and it started like 2009 and it's actively developed right now. We also have some tools for managing the proxy access that is the principal way of accessing internet in the beginning of the project. Also, Gifinette has collaborated in several European projects that involves research. For example, a confined project that lets developers try application and services and we bet that is a framework for testing on commodity with the hardware. Also, some projects like R&P modules and a distro for installing services. Now, Ivan will continue with the social project. Thanks. Before, at the end, I already introduced many of the tools and the concepts. Thank you very much, I cannot take where he is now. We have a big issue with the projects we developed and it's dissemination. Many people in the network don't even know that it exists. The long-term funding and maintenance, for instance, we had these European projects but now they are done, it's a little bit difficult to pay someone to actively develop such complex tools. Any idea or suggestion on this will be very, very welcome. Regarding the social project, very similar to what Adriano already mentioned, we consider the access to telecommunications and the internet to be a human right so we work towards that. We want to facilitate access to telecommunications and the internet and access that is affordable so it doesn't discriminate on how rich people or poor people, it's for everyone. We put special importance on the fact that some people, typically left behind, can access the internet like people in the rural areas where it all began. We call Gifineta Community Network because we feel a community, we know each other, at least locally, in the different areas. We are a pretty diverse community, of course we would like to be more diverse but I think it's okay right now. There are volunteers that participate in its expansion. We have all kinds of associations like EXO that I introduced you before. Gifibages, yeah, pretty big associations. We have companies that work on top of Gifineta and provide their services on their maintenance or installation of nodes and infrastructure. We have of course the users. We consider users to be also part of the community and we share their interests. We have the public administrations that help the network deploy by giving us access to some key places, key locations or is in the legislation as well. We have these very clear rules that I mentioned you before. We have this free open neutral network commons which is like the GPL license of Gifineta. Everyone that participates in the physical network itself must accept it explicitly by signing it. This is the base for everything else in the network. Like some of these governance tools like a complete resolution system that we apply when there are not so agreeable situations but there are and it has proved to work pretty well. And there is the foundation. The foundation is like a legal personality for the network whenever it is needed but it is not the owner of Gifineta. It is not Gifineta itself. It's a tool for Gifineta. And someone to guard for the network to develop according to the rules that I mentioned before. Legally it's a private not-for-profit foundation. It has many other roles that you can see here. And it is a telecommunications operator in Spain. It's a research resistor as such and it can provide access to other ISPs that want to share this connection in the catnics, in the neural exchange point in Barcelona that David mentioned before. And it's a common resource pool. This is a concept that was described by Eleanor Ostrom. It's a Nobel Prize winner. She introduced this concept and this has existed for millennia, for people running resources that must be shared between several people like the Earth. Fields or things like that. It's a very, very old concept. And when using such a resource concurrently, one must make an economic administration of it. So by the fact that everyone uses the same resource pool and develops it together, we can manage to make a more efficient use of it and to avoid some kind of duplicity that other ISPs and telcos produce just because everyone has to have their line and pay for it. And I think it's very efficient. We do not have that. So all participants cooperating in the development and service providers can offer their services at a price or there are services that offer them for members, many, many kinds of models running on top of it. Well, these are some of the professional services offered in the network. You will see internet access in the bottom because it's like a big local network but it does not provide access to the internet by default. So one of the ways or the many ways to access the internet besides web proxies and things like that are these ISPs that operate on top of Gifinnet, which are pretty competitive and much cheaper than other ISPs in Spain by grace of using this shared common pool resource. Okay, so to avoid another topic in common pool resource handling, which is the tragedy of the commons that is that someone uses the resource but doesn't provide anything to make it grow, we have this compensation system that applies to, let's say, big players in the network like big ISPs, big associations, volunteers that put a lot of effort. So we run this system where you can compensate collectively the resources that you put and the benefit that you get from the network. Okay, so to summarize, we have proof in these years that this kind of model can work. We have this sophisticated compensation system that has been awarded by the European Union in 2015, I think. So, 16 there was another network, a Scottish network, I think it was a community network that also got a similar price. Yes, we have the recognition of the European Union. I think we can, it has proved sufficiently that this can be a model for future access to the, for providing access to the internet to everyone and affordable and... More efficient than the resources. Yeah, in an efficient and socially good way. So, thank you very much for listening. If I have any questions. Thank you. We'll play this video in the background while you... Ask questions. If you have any questions. Six minutes for questions. Don't forget to repeat the question. Okay. Let's put it five first times. Faster. It usually... So the first question is how do we provide the internet access with tablets or whatever? For example, I can explain the XO use case. We use IP IP tunnels, but there are some... There are ISPs that use IPv6 mainly and do... NAT operator for the IPv4. For example, there are many techniques use it. It depends on the operator itself. Can you repeat it? Can you repeat it? Well, yeah. You ask about the routing and... Yeah, you are asking that how we manage the routing in all the network. Well, we use mainly BGP and... OSPF. And well, there are some partitions on the network. They start as islands and the users decide which protocol use and then when they join the network, there are some problems that we must solve using filters or any technique. The political situation in Barcelona and Catalonia in general influenced the development of the internet in the last couple of years. So the question is, how did the political situation in Barcelona or Catalonia influence the... How it influenced the growth of the internet? We changed something. So I wouldn't be sure to say that this QMP project was born in some way to support the very quick deployment of a mesh network. QMP is a quick mesh project. So I don't know if you can consider this to be supporting some kind of political movement. The city of Barcelona became kind of the turf of the social movements. So maybe you have more support now from what you have before. Did it change anything? So regarding what he said about the political movement in Barcelona, that changed very alive in the last years. We got support from them but we are very informal ways of getting support. I wouldn't be able to answer. It seems that there is some interest as we can see in the social meetings that the major is interested in. Yeah, the major house. The major house is interested and we got support. It seems that interest has grown. The conduct for end users, how do you make them sign them? Is it only for end point users or for end devices users? Like the family of three. Everyone has to sign it? So regarding how does people sign this agreement, the commons? How do we do it? How is that? They have to register on the website so they can place the note of the network and configure it and for registering you have to accept the contract. It's one per note. One per user and with a user you need a user to create a note. We assume that they read it and use it. As all the services do. But when introducing the concept of the network, we are told by signing it also. So the question is if EXO is an ISP and how do we get and if we need to connect directly to the EXO in the catnics or we must go over other notes. The infrastructure of GIFINET is the free path and EXO is available through GIFINET. So in particular we have a machine at the catnics hosted with other machines of GIFINET of the foundation. And through GIFINET we reach the servers and then we establish tunnels, except technology, but it's done like this. I think it's done like this for other ISPs. You reach their servers and directly. There are some optical fiber links from the catnics and there are some GIFINET connected directly by these optical fiber links. Directly. I'm an example. He's asking that if you can connect directly to the catnics, yes you can. Yeah, yeah, yeah. It's time's up. He's a fortunate owner of another that connects directly to the Teldon building where? I can explain it like a catnics. Okay, thank you very much.
