Can we map the Internet?

on Monday, 22 July 2019 Posted in News GrenoblIX, News Rezopole, News LyonIX

Can we map the Internet?

Since the Internet is considered as a space, is it possible to provide a complete graphic representation, to draw one or more maps? Artists and experts have been trying for a long time.

 

To find an answer, the first tool was Google. The results in French mainly show Internet maps seen from the outside. For those in English, we get some visualizations of the weight of sites in number of connections.

 

Boris Beaude, a geographer and researcher at the University of Lausanne, explains that mapping the Internet "makes it possible to better understand the architecture[of the Internet and its sub-areas, such as websites], the actors who produce them, the reality of what is happening there and the underlying power issues".

This is not a fundamentally recent idea, since he himself studied the subject at the end of the 1990s. He noted that "the continuation of TCP/IP protocols, or even packet switching alone, is based on essentially spatial considerations: how to make communication as efficient as possible on heterogeneous and vulnerable networks".

 

Beyond the researchers, some artists have also looked at the issue. An American designer, Chris Harrison, represented the journeys that data makes around the world. He explains his gesture quite simply: "Humans have always tended to represent graphically the spaces in which they evolve. Now the Internet, we walk around, it moves, there are millions, trillions of tools connected to each other".

 

Louise Drulhe was looking to represent the Internet for her diploma from the Ecole des Arts-Déco. She then faced two difficulties. The first is that the space in which we operate online is constantly changing. She explained to Numerama "it's terrible to want to represent cyberspace, because the speed at which it changes has nothing to do with geography. When I started working on my first maps in 2013, we were barely talking about the Chinese Internet, for example".

The second is the very low number of representations of the online space. "In 2013, I was working on a thesis on Internet space, but I quickly realized the lack of information on online space as I understood it. There were some old maps from the 90s. But it had nothing to do with the current cyberspace," says the young woman.

 

According to Boris Beaude, the lack of representations is explained by the fact that it is the "powerful imaginaries, which suggest that all the spatial vocabulary associated with the Internet is metaphorical". He attributes this mixture to "a materialistic conception of space". The territory and "the materiality of the ground on which our feet rest" would too often be confused with the idea of spatiality.

 

So what measures for an online space? For Boris Beaude, "distance is thought in terms of gaps, contact or interaction. This allows us to think about the relationship and how beings (and more and more objects) are connected and interact". And to show the architectures that facilitate these contacts.

 

Louise Drulhe has opted for a multiplicity of hypotheses that suggest a different aspect of the Internet. But all of them meet the same need: "representing the Internet helps us to understand the (geo-)political issues at stake".
The artist does not stop there since his last hypothesis is that of an Internet architecture that would be specific to everyone. It may not be possible to map the Internet for the simple reason that no road is used exactly twice in the same way.

 

Boris Beaude responds to this by opposing personal navigation and the power of the world's largest networks: "Google and Facebook are the two players with the greatest visibility on contemporary digital spatialities". Paradoxically, therefore, "while it is difficult to map the Internet because the relationships that constitute its space are so disproportionate and reticular, it has never been so simple for those who have mastered it to map the spatiality of individuals".

And to conclude that "politicians will have to ask themselves what they are trying to control: things[in this case, data, editor's note] or the movement of things and the architecture that makes this movement possible". A cross-border and disproportionate space par excellence.

Arcep: Open Internet

on Thursday, 11 July 2019 Posted in News GrenoblIX, News Rezopole, News LyonIX

Arcep: Open Internet

The Autorité de Régulation des Communications Électroniques et des Postes is publishing the 2019 edition of its Internet Health Check in France. Submitted to Parliament, this report highlights the actions taken to ensure the openness of the Internet, looks at potential threats and presents the regulator's action to contain them.

 

The balance sheet in brief!

 

1- Quality of services
The service comparators are so inhomogeneous today that the Arcep wanted to improve them by setting up an API in the boxes containing the "access identity card" of each terminal. This will allow a much better diagnosis with reliable information on the parameters of each measurement. This API is complemented by a code of conduct. Gradually adopted by the measurement stakeholders, it makes it possible to improve the reliability, transparency and readability of the results.

 

2- Data interconnection
In constant evolution, this ecosystem can be the site of occasional tensions. The Arcep is vigilant in monitoring the market. It publishes data from its information collection in its annual barometer of interconnection in France. When the situation requires it, the Arcep can also become a "gendarme" and settle disputes between the actors.

 

3- Transition to IPV6
The end of IPV4 is now scheduled for June 2020. Operators' planned deployments of IPV6 may not be able to address the shortage of IPV4 addresses. Therefore, Arcep will organise the first working meeting of the "IPV6 Task Force" in the second half of 2019. These meetings will aim to accelerate the transition to IPV6 in France by sharing the experiences of the different actors and defining actions to be implemented

 

4- Net neutrality
The guidelines for the implementation of the principle of net neutrality by national regulators have generally proved their worth. The country has a positive balance sheet. However, Arcep ensures that access providers continue to adjust their practices in line with the European regulatory framework.

 

5- Opening of terminals
If in terms of net neutrality, the Arcep can exercise its protection on networks there is a weak link: terminals. Adopted at the beginning of this year, the European "Platform-to-business" regulation brings more transparency on the practices of online platforms towards their corporate clients. However, this regulation does not yet ensure the neutrality of terminals. Arcep made 11 concrete proposals to ensure an "end-to-end" open Internet in a report on the issue in February 2018.

3.8 billion people now have access to the Internet

on Thursday, 11 July 2019 Posted in News GrenoblIX, News Rezopole, News LyonIX

3.8 billion people now have access to the Internet

Since 1995, Mary Meeker, an investor in the powerful venture capital firm Kleiner Perkins Caufield & Byers, has been reporting on major Internet trends. An analysis of the global use of the Web and its services: e-commerce, social networks, video games, podcasts, various connected objects, etc.

 

The 2019 edition has reached a new milestone! According to the document, more than half (51%) of the world's population now has access to the Internet, or more than 3.8 billion people worldwide. Whereas in 2009, just ten years ago, this rate was only 24%. China, India and the United States are the three countries with the most Internet users in the world.

 

Nevertheless, global growth is slowing every year. Between 2018 and 2019, it was 6%. Indeed, for Mary Meeker, it is more difficult to connect new people as the number of Internet users increases.

 

The report details, for example, that Americans spend 6.3 hours online per day. An average increase of 7% compared to last year. They now spend more time in front of their mobile phone (almost 4 hours a day on average) than in front of their television (about 3h30).

 

The document also includes the 30 most highly valued new technology companies in the world. Of these, 18 are American, 7 are Chinese and only 1 European (Spotify, the Swedish music application, is ranked 30th in this ranking).

The Internet network is drowning

on Tuesday, 02 July 2019 Posted in News GrenoblIX, News Rezopole, News LyonIX

The Internet network is drowning

Fibre optic cables, data transfer and storage stations and power plants form a vast network of physical infrastructure that underpins Internet connections.

 

Recent research shows that a large part of this infrastructure will be affected by rising water levels in the coming years. After mapping the Internet infrastructure in the United States, scientists overlayed it with maps showing sea level rise. Their results: in 15 years, thousands of kilometres of fibre optic cables and hundreds of other critical infrastructures are at risk of being overwhelmed by the waves. Still according to the researchers, the extra few centimetres of water could plunge nearly 20% of the U.S. Internet infrastructure underwater.

 

"Much of the existing infrastructure is located just off the coast, so it doesn't take much more than a few centimetres of water to get it underwater", says Paul Barford, a scientist at the University of Wisconsin, Madison, and co-author of the study: The network was deployed 20 years ago, when no one thought that sea levels could rise.

The physical structure of the Internet network has been installed somewhat randomly and often opportunistically along power lines, roads or other major infrastructure in recent decades when demand has exploded.

 

While scientists, designers and companies have long been aware of the risks posed by rising water levels on roads, subways and power lines, no one has so far been interested in the consequences that this could have on the physical Internet network.

"When you consider how interconnected everything is today, protecting the Internet is crucial", says Mikhail Chester, director of the Resilient Infrastructure Laboratory at the University of Arizona. Even the smallest technical incidents can have disastrous consequences. He continues "this new study reinforces the idea that we must be aware of the state of these systems, because it will take a long time to update them".

Rich Sorkin, co-founder of Jupiter Intelligence, a company that models climate-induced risks, says, "We live in a world designed for an environment that no longer exists". And concludes by saying that "accepting the reality of our future is essential - and this type of study only underlines the speed with which we will have to adapt".

Operators want to avoid overheating

on Tuesday, 02 July 2019 Posted in News GrenoblIX, News Rezopole, News LyonIX

Operators want to avoid overheating

Telecommunications operators are concerned about the impact of this heat wave on their infrastructure networks. Just as heat waves can affect smartphones, tablets and other laptops, the infrastructure underlying telecommunications networks can also suffer in hot weather. Indeed, the electricity network, which is heavily solicited and subjected to high temperatures, can fail this equipment. They can then stop working in a punctual and localized way.

 

But the real "vulnerability" of these infrastructures is concentrated on two specific network points: relay antennas and data centres. Depending on the equipment considered, the temperature threshold not to be exceeded is around 50 degrees Celsius.

Relay antennas are particularly exposed to high temperatures since they are located at high altitudes, particularly on the roofs of buildings in urban areas. The risk of their electronic components going into standby mode in the event of overheating is therefore not negligible.

Depending on their air conditioning systems and exhaust air devices, data centres risk overheating if they fail to operate.

 

All the attention of the operators is focused on not exceeding 50 degrees Celsius. "We have set up a weather monitoring system to enable us to prevent in the event of a natural disaster and to analyse the good performance of each point of our network [...] Over the past few months, we have focused our preventive campaigns on monitoring the maintenance and air conditioning equipment in our infrastructures for greater safety", explains Hubert Bricout, Bouygues Telecom's Regional Director for Ile de France and the North-East.

In the event of a site failure, rapid response teams will be dispatched. To support the systems already in place, mobile air conditioning equipment has also been reserved in the event of overheating of a network point.

The Data Center Continuum

on Tuesday, 25 June 2019 Posted in News GrenoblIX, News Rezopole, News LyonIX

The Data Center Continuum

The visionary trend of the 2010's massively positioned data center surfaces in Hyperscale DCs, ideally located in areas close to the Arctic Circle. At the time, only the issue of systemic risks seemed to be able to slow down this development.

 

But today the reality is no longer the same. Indeed, a continuum model has replaced this vision of hyper-concentration of surfaces, which can be summarized in 6 levels.

  • Hyperscal Data Centers are still attractive for mass storage and non-transactional processing. Their objective is to bring the best production cost, by positioning a large area pooling where land and energy are cheap.
  • Hub Data Centers are mainly located in Frankfurt, London, Amsterdam and Paris in Europe. These areas concentrate large data centers and benefit from fast interconnection between them. These areas over-attract operators because interconnection takes precedence over the potential of the local market.
  • Regional Data Centers, located in all other major cities, address this time the local economic potential, with cloud players for companies or hosting providers acting as first level access to DC Hubs.
  • "5G" Data Centers will be located as close as possible to urban areas in order to meet the need for latency required by population uses.
  • Micro-Data Centers will bring low latency during a high concentration of use (a stadium, a factory).
  • Pico-Data Centers will address the use of the individual, thus bringing a minimum latency and especially a management of private data.

 

Despite different sizes, the first three levels of these data centers follow the same design principles. Except that Hyperscal Data Centers are often single users. It is therefore possible for them to position more restrictive design choices than in shared apartments.

The last three levels belong to the Edge universe and aim to position the DC space as close as possible to usage. However, these levels have different design principles.

The installation will be done in an industrial way for micro and pico-Data Centers. The main issues will be more related to physical protection or maintenance/operation of these infrastructures.

The "5G" Data Centers bring a new deal. Indeed, they have all the characteristics of a "small" DC but must be implemented in complex environments. They are subject to numerous safety and standards compliance constraints being located in urban areas. However, the greatest complexity lies in the lack of space to deploy the technical packages.

5G : clean slate on the 1.5 GHz band

on Tuesday, 25 June 2019 Posted in News GrenoblIX, News Rezopole, News LyonIX

5G : clean slate on the 1.5 GHz band

In the fight expected from operators for the acquisition of frequencies dedicated to 5G, the Regulatory Authority for Electronic Communications and Posts is preparing to open a new front. Indeed, last weekend Arcep reported that it had set 31 December 2022 as the maximum deadline for frequencies in the 1.5 GHz band, known as the L band.

 

"Today used for point-to-point links for the collection of mobile networks open to the public and professionals and by the Ministries of the Interior and Defence", its release by the end of 2022 should allow mobile operators to have more frequencies to deploy future 5G and Very High Speed networks.

"The 1.5 GHz band has been subject to European harmonisation since 2015. It has 90 MHz that can be used to meet downlink requirements. The propagation properties of these frequencies are particularly interesting for the coverage of the territory and the coverage inside buildings", said the Telecom Constable.

 

However, there could be many pitfalls.... Indeed, the current tenants of the band have already sent comments to the Authority during the consultation period: a disputed reallocation plan, potentially huge migration costs.

 

However, the decision is widely welcomed by operators who are pleased to be able to obtain new frequency blocks for the development of their future 5G networks. While the latter accept that this L-band will only be operated "for additional exclusively downlink links (in SDL mode)", it will still improve the throughput and capacity of downlinks below 1 GHz.

The spectrum available for the deployment of future 5G networks is relatively limited, so this release should be of significant interest to operators, particularly in the event of coupling with other frequency bands.

Operators are also unanimous that the entire band will not be able to operate effectively due to unfavourable neighbourhood conditions. On its adjacent bands, there are "space exploration satellite services, radio astronomy and space research services", which do not allow the use of both ends of the 1.5 GHz band. Orange has only one 85 MHz band that can be used, while Free goes further with only one 40 MHz band. For the operator, this block of frequencies constitutes "the only sub-band with a mature ecosystem today" and could even be the subject of an "immediate allocation scenario" via a reallocation of 10 MHz bands to each operator.

 

A scenario that will not be retained by Arcep but which illustrates the operators' appetite for this band, to the great displeasure of its current tenants. They should be required to be housed elsewhere, particularly in the 6 GHz band.

Most of these actors are industrialists and express doubts about the Arcep's decision and its implications for their own activities and finances. Questions about the economic viability of this migration on the part of EDF, for example, for whom "the estimated time required to replace 1.4 GHz links, without significantly impacting the company's performance, is around ten years".

Especially since the timetable imposed by the telecoms police officer is already causing the actors concerned to shudder. For Enedis, the deadlines proposed jointly by Brussels and Arcep "do not take into account this specific framework for the use of the 1.4 GHz band by Enedis, nor the current limits or the constraints imposed by the alternative solutions". And even one of the alternatives proposed by Arcep would involve the reconstruction of a large part of its network.

The public authorities also seem to be waiting, as does the Ministry of Transport, for whom the timetable mentioned cannot be kept. Hence the Ministry's request to maintain the current network "at least until 2027, knowing that if studies show that it is possible to have the future network available earlier, the network can be shut down before that date".

Current tenants propose other solutions such as the establishment of a "cohabitation context". This would allow L-band frequencies to be allocated to operators in dense urban areas and other actors to "continue to use Radio Beams in rural areas, which are less likely to be targeted by the need for SDL".

Increase in expenses dedicated to DataCenters

on Wednesday, 17 April 2019 Posted in News GrenoblIX, News Rezopole, News LyonIX

Increase in expenses dedicated to DataCenters

Driven by a booming cloud infrastructure market, hardware and software spending in DataCenters increased by 17% in 2018. A global market dominated by Dell EMC followed by Cisco, Hewlett Packard Enterprise and Huawei. Investments driven by a "growing demand" for public cloud services and the need for "ever richer" configuration according to Synergy Research Group, which publishes these figures. As a result, the average selling price of enterprise servers has skyrocketed.


In more detail, spending on infrastructure purchases for the public cloud increased by 30% compared to 13% for those directed at equipping enterprise data centers. "Cloud services revenues continue to grow by nearly 50% per year," said John Dinsdale, analyst at Synregy Research Group. "SaaS and e-commerce revenues are each increasing by about 30%. All these factors contribute to a significant increase in spending on public cloud infrastructure," he adds.
The public cloud market is dominated by the MDGs, which account for the largest share of cumulative revenue. On the brand side, Dell EMC is ahead of Cisco, HPE and Huawei. Dell EMC is also a leader in the private cloud market, followed by Microsoft, HPE and Cisco. These four providers are the leaders in the non-Cloud Data Center market, but in a different order.


Total revenue from Data Center equipment, including both cloud and non-cloud hardware and software, is $150 billion in 2018, the analyst said. The Data Center infrastructure market is 96% composed of servers, operating systems, storage, networking and software. Network security and management software represent the rest.
By segment, Dell EMC leads in terms of server and storage revenue. Cisco, on the other hand, overlooks the network segment. Then there are Microsoft, HPE, VMware, Lenovo, Inspur, NetApp and Huawei, which recorded the strongest growth in one year.


"We are also seeing relatively strong growth in infrastructure spending in enterprise data centers, with more complex workloads, hybrid cloud requirements, increased server functionality and higher component costs being the main drivers," concludes Dinsdale.

Agreement between Kosc Telecom and Ielo-Liazo

on Wednesday, 03 April 2019 Posted in News GrenoblIX, News Rezopole, News LyonIX

Agreement between Kosc Telecom and Ielo-Liazo

Signed on 28 March, this strategic agreement between the two operators of French operators was concluded for a period of 20 years. It concerns access to their respective infrastructures.


Indeed, Kosc Telecom provides its FFTH collection infrastructure via its bitstream offer. This allows its new partner to enrich its catalogue of services and complete its offer of residential collection on existing copper support (xDSL).
Ielo-Liazo, for its part, is opening up access to its national fibre network via a new industrial NRO optical unbundling offer. This will enable Kosc Telecom to deliver high quality services and strengthen the national coverage of its Enterprise Fibre network.


This long-term partnership between these two operators, specialists in the wholesale of telecom products, represents for Ielo-Liazo a concrete application of its strategy aimed at offering the enterprise market a unified infrastructure offer for operators. While it is a complementary step for Kosc in its strategy to offer its customers operators 100% of the lines available in France.

Digital Industry Observatory

on Tuesday, 20 November 2018 Posted in News GrenoblIX, News Rezopole, News LyonIX

Digital Industry Observatory

Produced by EY in partnership with the Auvergne-Rhône-Alpes region, the 3rd edition of the Auvergne-Rhône-Alpes Digital Industry Observatory was unveiled by the Digital League on 5th November last.

Representing nearly 65,000 jobs, digital technology is now a central pillar of the regional economy. Indeed, this industry created more than 3,000 jobs between 2016 and 2017, as many as the region's 4 main flagship industrial sectors combined (chemistry-rubber-plastic / metallurgy-metalworking / machinery and equipment manufacturing / agri-food).


This dynamic is confirmed at the national level as Auvergne-Rhône-Alpes consolidates its position as the second region in the digital sector with the creation of 8,150 jobs between 2013 and 2017. Internationally, despite a decline of two places compared to the period 2011-2015, Auvergne-Rhône-alpes ranks 20th among European regions that have attracted the most foreign investment in digital technology. It is one of only two French regions to be included in the TOP25.

Encouraging figures and resolutely confident players. Indeed, 81% of digital companies expect sales to increase by 2018, with the development of current services and products as the primary growth driver. However, the difficulty in recruiting the right profiles remains the first obstacle for regional actors, with an increase of 11 points compared to 2017.

In this 3rd edition of the Observatory, digital players also share their point of view on what they consider essential to make digital transformation a lever for growth and acceleration for all industries. For example, 75% of the companies surveyed believe that, long before the understanding of technological issues and the development of a digital culture, change management is the most important thing.

Data centers: a hot topic for our data

on Thursday, 06 September 2018 Posted in News GrenoblIX, News Rezopole, News LyonIX

Data centers: a hot topic for our data

Located south of Paris, the Data4 campus hosts the data of major CAC 40 companies. Among the nine data centres spread over 111 hectares, is DC05. This new-generation data center, in service since the end of 2017, has a single facade, clad with blocks capable of drawing in external oxygen. "Once filtered, this air at room temperature is used to cool the core of the building, or the temperature of some components can easily rise to 60°C. This free cooling system replaces the frozen water reserves and large mechanical cold cabinets used in older data centres," explains Jérôme Totel, site manager.

Free cooling is in vogue and is becoming increasingly popular, mainly for economic reasons. Indeed, data centers consume nearly 10% of the world's electricity. "And nearly half of this energy is used to operate cooling systems," explains Guilhem Cottet, General Delegate of France Datacenter. Today, the temperature range of air sent to server rooms is much higher than it was ten years ago. Indeed, international guidelines recommend between 20 and 27°C.

However, "cooling a data center is a real science," says Jean-Michel Rodriguez, Chief Technology Officer at IBM. The ambient temperatures and humidity in the northern European countries naturally ensure good cooling throughout the year, making it easier to use free cooling. However, this is not the case with a more Mediterranean climate since this system can only operate for part of the year. Hosting companies therefore often rely on more modest installations such as simple air conditioning coupled with "cold aisles". "Each year brings its share of new products. We are in a state of constant optimization," confirms François Salomon, Schneider's free cooling specialist.

 

This is the case, for example, of Facebook, which last June revealed a system combining free cooling and water, or Lenovo, which relies on liquid cooling. 2CRSI, a Strasbourg-based company, offers a shared cooling system. Many researchers are currently working on algorithms that can reduce server consumption. Although the energy efficiency indicator for data centres has improved significantly in recent years, some experts are sounding the alarm bell. "Calculation and energy needs will increase exponentially. To develop artificial intelligence, optimizing cooling will not be enough. So much so that we will have to rethink the design of our data centers," warns Pierre Perrot of CryoConcept.

 

This observation has led engineers to develop diametrically different technologies such as immersion. Asperitas now immerses its servers in oil. "It is a non-conductive and non-corrosive liquid that absorbs up to 1,500 times more heat than air," says Pierre Batsch, head of the company's development in France. Thus there is no need for air conditioning, false ceilings, cold aisles, etc. While Alibaba has already announced a similar project for some of its servers, other players such as "cryptomone mining" factories or the financial world are also interested in this solution.

Microsoft has decided to immerse part of its infrastructure in the ocean. "Water is 800 times denser than air. When you touch it, you are in contact with many molecules, which means you can transfer heat faster and more efficiently," explains Ben Cutler, project manager at Microsoft. But this initiative is met with some criticism: "Will the heat released have an impact on the marine ecosystem? Wouldn't it be better to reuse it?," persimmates an expert. These remarks will not discourage Microsoft, which has not finished making waves.
