IPv6 mandatory for Belarusian ISPs

on Friday, 27 September 2019 Posted in Archives Rezopole, Archives GrenoblIX, Archives LyonIX

IPv6 mandatory for Belarusian ISPs

Belarus becomes the first country in the world to legally require the adoption of IPv6. As of January 1, 2020, all Internet Service Providers will be required to support IPv6 on their network and provide an IPv6 address to all their customers.

 

The new law was promulgated by presidential decree on 18 September. This decree updates the previous one setting out the rules for using the country's "national Internet segment". Belarus has one of the newest and most modern Internet backbones on the European continent and local ISPs have already tested IPv6 support well before last week's announcement.

 

Currently, IPv6 adoption in Belarus is about 15% on average, below the global average (29%). But this is expected to increase from 2020 onwards, as local ISPs will have to support all connections.

Once enabled, clients will be assigned both an IPv4 Internet address and an IPv6 address, and connections will run fully on IPv6 if possible.

 

Officially approved as the Internet standard in 2017, IPv6 was designed to replace IPv4, which has almost exhausted its available address space of 4.3 billion addresses. Since its adoption, ISPs around the world have begun to deploy support, in collaboration with consumer and professional device manufacturers. A rather slow deployment, mainly because it was left to the discretion of the operators.

Kosc counter-attacks before the Council of State

on Friday, 13 September 2019 Posted in Archives Rezopole, Archives GrenoblIX, Archives LyonIX

Kosc counter-attacks before the Council of State

Kosc was unsuccessful against Altice and contested the decision taken by the Competition Authority. Indeed, seized on the occasion of the sale of Completel's copper network, the competition police last week issued its verdict: "there is nothing to define that Altice has committed a fault with regard to its obligations".

 

This is a major blow for the wholesale provider of telecom services to operators in the enterprise market, which has been denouncing SFR's parent company's late deliveries for months. This decision is all the more difficult to accept as its financial equation has become significantly more complicated.

 

But the operator does not intend to stop there since he "rejects", in a press release, the verdict of the Competition Authority and announces that he will bring the case before the Conseil d'État. A referral "motivated by the numerous irregularities that have marked the follow-up of the case by the Competition Authority, including the unexplained duration of its investigation in a context of urgency and the probable violation of its secrecy".

In addition, the company believes that the abandonment of Banque des Territoires (Caisse des Dépôts group), one of its main supporters, can only be explained by an understanding of the result favourable to Altice - SFR upstream.

 

Kosc warns against a prospect of consolidation that it now considers itself the "privileged target of a hostile acquisition" in view of its financial fragility. An operation that would "de facto close the business telecommunications market to the detriment not only of the ecosystem of hundreds of digital business service operators but also of the beginning of catching up on the digitalisation backlog of French SMEs and VSEs", warns the operator.

Arcep : Orange "attacks the French regulatory model".

on Friday, 13 September 2019 Posted in Archives Rezopole, Archives GrenoblIX, Archives LyonIX

Arcep : Orange

In its newsletter on Monday, the Arcep college published an editorial to review the implications of a recent picket by the incumbent operator. Indeed, at the end of the summer, Orange submitted a Priority Question of Constitutionality (QPC) to the Conseil d'Etat in order to challenge the telecoms regulator's power to impose sanctions. But according to the college, Orange "[challenges] the pragmatic spirit of French-style regulation". With this initiative, the incumbent operator "does not attack the Arcep so much but attacks the French regulatory model more broadly", says Sébastien Soriano, President of the Arcep.

 

The sanctioning power of the Arcep is vital for the proper functioning of the current regulation, the college stresses in its editorial. In particular, it would not be possible to benefit from "the commitments that operators can make on competitive or territorial coverage issues", argues the telecoms police officer. "Without control and sanctions, these commitments would only be paper," he insists.

 

Very upset by the initiative of the incumbent operator, Sébastien Soriano said "I am not sure that Orange has measured all the consequences". The President of Arcep says that if his power of sanction were to disappear, then France would have to choose another regulatory model. Wishing to take advantage of the "synergy between infrastructures and services", it decided to leave the incumbent operator in charge of its network for its deployments.

Sébastien Soriano explains "We felt that Orange, because of its need to win back customers in the fixed Internet, had an incentive to invest in fibre", seeing it as a "positive market dynamic. But the counterpart of this choice is that the regulator must check on a daily basis that Orange is not taking advantage of this situation by giving itself an advantage on the retail market. This is called non-discrimination. To ensure this, regular monitoring and sanction procedures are required. Without them, we would potentially be forced to choose much more radical regulatory approaches..."

And ends by correcting: "It's not a threat, it's factual".

Global bandwidth : total throughput of 446 Tb/s

on Thursday, 05 September 2019 Posted in Archives Rezopole, Archives GrenoblIX, Archives LyonIX

Global bandwidth : total throughput of 446 Tb/s

Of course, the international bandwidth is increasing, but this masks a rollercoaster evolution in recent years. This is at least what a study published on Wednesday by the Telegeography Research Institute found.
Indeed, according to this analysis, global Internet bandwidth increased last year by only 26%, the lowest annual growth rate in at least 15 years. Although the pace is slowing, international bandwidth has almost tripled compared to 2015.

 

A dynamism attributed, by Telegeography, largely to the African continent. With a compound annual growth rate of 45% between 2015 and 2019, it is the continent that has experienced the fastest growth. The Asian continent is not to be outdone, with its bandwidth volume reaching a compound annual rate of 42% over the same period.

 

"Since we started tracking international Internet capacity in 1999, the most efficient channel has always been between Europe, the United States and Canada. This route was overshadowed by the Latin American-US and Canadian route, which experienced an explosion in bandwidth," according to the research institute.

 

A paradigm shift due in particular to a better integration of the countries of the American bloc, "while Asia and Europe have a greater diversity of connectivity". The researchers also note that content providers have an increasingly important role to play as they now dominate the creation of the backbones of the global Internet through submarine cables. The latter connect the different Atlantic or Pacific coastal countries. In view of the latest transcontinental submarine cable projects, the evolution described by Telegeography does not seem likely to slow down.

Orange wants to cut the whistle of the Arcep

on Thursday, 05 September 2019 Posted in Archives Rezopole, Archives GrenoblIX, Archives LyonIX

Orange wants to cut the whistle of the Arcep

The incumbent operator has submitted a Priority Question of Constitutionality to the Council of State, which can thus deprive the telecom police of its sanctioning powers and render the operators' commitments ineffective.

 

Unveiled on Tuesday by Le Monde, this request challenges the legal validity of a formal notice sent to it by Arcep last January. Indeed, the regulator criticized Orange for not respecting its obligations towards other telecom operators when it makes its fixed networks available to them. For the time being, this request is only at the preliminary stage. It will only be examined by the "Wise Men" of the Constitutional Council if the Council of State decides to transfer the file to it.

 

But in reality, it is a much broader problem. The incumbent operator argues that Arcep is both judge and party at the same time and that there is too much permeability between its three missions: to enact rules for the market, to control telecom operators and also to sanction them in the event of non-compliance with their obligations.
The regulator would de facto be deprived of its power to impose sanctions if the Conseil d'État were to rule in favour of the operator. In short, if the Arcep can no longer sanction abuses, the shipyards will fall behind and the objectives to boost French access to very high speed will not be met.

 

Orange assures that the procedure is a legal issue and will not affect the commitments made. The operator points out that in 2013 the Arcep has already been deprived of its power to impose sanctions in a similar procedure.

4A page is turning for the French sovereign cloud

on Wednesday, 07 August 2019 Posted in Archives Rezopole, Archives GrenoblIX, Archives LyonIX

4A page is turning for the French sovereign cloud

The Cloudwatt, Orange's online data hosting service, will be disconnected on February 1st. Launched in 2012, it was one of the two heads of the French-style sovereign cloud co-financed at a loss by public money. With Bercy calling again for the creation of secure data centers to host sensitive government and corporate data, this failure could serve as a lesson.

 

At the origin of this project, called Andromeda, France wanted to invest 150 million euros in a shared server service that could reduce the costs of ministries and companies. But here we are, the French technology groups called upon to help did not succeed in reaching an agreement and therefore shared the envelope.

On the one hand, Cloudwatt was created by Orange and Thales by adding 150 million euros to the amount provided by the State. On the other hand, Numergy was launched by SFR and Bull with the same investment. However, none of them were able to find customers. And two years after their launch, Cloudwatt claimed only 2 million dollars in revenue. Even if Numergy was doing better with 6 million billed, these are crumbs compared to Amazon, Microsoft and IBM.

Bercy stops the expenses, a few months later, by assuring that she has spent only half of the promised sums. Orange and SFR then bought back the shares of the State, one from Thales and the other from Bull. Numergy and Cloudwatt, which had then become simple brands, had since been part of the offers designed for large companies by the two telecoms operators.

 

Today, the dominance of American players in the online IT market continues to raise concerns about the integrity of critical data. A recent report by MP Raphaël Gauvain criticizes the Cloud Act, an American extraterritorial law recalling the Patriot Act and spy programs.

The Government should therefore sign a strategic supply chain contract to develop a "Cloud of Trust" ecosystem in the fall. Being French will not be enough to be French and some American or Chinese technologies used in French data centers will be difficult to support.

"This time, we will not assume the nationality of the actors but their ability to guarantee data integrity with regard to our laws and strategic autonomy over our essential infrastructures and data," notes Jean-Noël de Galzain, Hexatrust's president on the sector's strategic committee. In addition, the State should commit itself to playing its role as a buyer.

4G: the Arcep hits the table with its fist

on Wednesday, 07 August 2019 Posted in Archives Rezopole, Archives GrenoblIX, Archives LyonIX

4G: the Arcep hits the table with its fist

The telecoms police officer has just sent an early formal notice to Orange, SFR, Bouygues Telecom and Iliad-Free regarding the "New Mobile Deal". Indeed, Arcep considers that the commitments made by operators under this agreement, dating from January 2018, are not progressing fast enough.

 

At the time, the State agreed to renew part of the frequencies granted to operators for ten years and free of charge. A "gift" with a counterpart, however: the operators had undertaken to cover the territory more, particularly in the famous "white areas".

By the end of 2020, they must have converted all their existing 2G and 3G sites to 4G and improve mobile coverage on transport routes (from 2018) and inside buildings (from 2019).

 

But a year and a half after the signing, the regulator would find that progress was insufficient. "The regulator has no confidence in the operators, he believes that this case is dragging on," explains a source familiar with the case.

If the targets were not met by the 2020 deadline, early warning would make it possible to initiate sanctions more quickly without wasting time.

 

Aware that operators have always had difficulty meeting their commitments, the government has organised progress reports on the progress of the work. This was obviously not enough.

However, in June 2018, the government published the first 485 sites on which operators had to install their 4G antennas. For its part, the Arcep had launched its quarterly dashboard. But several observers had already warned of the magnitude of the task. "The deadlines were super-short. We could legitimately be concerned," recalls one participant today.

 

Operators, on the other hand, deny any delay. "Operators are deploying on schedule. ...] We are on the ground every day to solve administrative and technical challenges with the support of communities and government services. Arcep is welcome in the territories and will thus become even more aware of the collective success underway to finally solve the problem of white areas," said Arthur Dreyfuss, President of the French Telecommunications Federation. Summer is therefore likely to be turbulent.

Tracking the exhaustion of IPv4 addresses

on Thursday, 01 August 2019 Posted in Archives Rezopole, Archives GrenoblIX, Archives LyonIX

Tracking the exhaustion of IPv4 addresses

Used since 1983, Internet Protocol version 4 (IPv4) allows the Internet to work: each terminal on the network (computer, telephone, server, etc.) is addressable by an IPv4 address. This protocol offers an addressing space of nearly 4.3 billion IPv4 addresses. But the success of the Internet, the diversity of uses and the multiplication of connected objects have as a direct consequence the progressive exhaustion of these addresses. By the end of June 2018, the four major French operators (Bouygues Telecom, Free, Orange, SFR) had already assigned between 88% and 99% of the IPv4 addresses they own.

 

Only 2.856 million public IPv4s remain available at RIPE NCC as of July 23th, 2019.

Two scenarios are now possible:

  • 1: allocation of 1024 IPv4 addresses by LIR until depletion.
  • 2: allocation of 1024 IPv4 addresses by LIR until the last million available IPv4 addresses, then 256 IPv4 addresses by LIR until depletion.

The most likely date for IPv4 depletion is May 6, 2020 (scenario 2).

If RIPE proposal 2019-02, allowing to limit to 256 IPv4 per LIR (scenario 1), is rejected, it will be on December 25, 2019.

 

On the day of the exhaustion of RIPE-NCC IPv4, the price of IPv4 on the secondary market for the purchase of already allocated addresses is expected to soar according to supply and demand. Indeed, players who have too many IPv4 addresses can sell them to those who do not have enough or none at all.

A high price that could erect an entry barrier against new market players and increase the risk of the development of an Internet split in two: IPv4 on the one hand and IPv6 on the other. As Jérémy Martin, Technical Director of Firstheberg.com explains: "With increasing demand for a fixed number of IPv4, the cost of renting an IPv4 will double in the next 2 years"

 

To address the shortage of IPv4 addresses, ISPs have implemented some alternative mechanisms. For example, Carrier-grade NAT (CGN) equipment allows an IPv4 address to be shared between several clients. However, they have several negative effects that make it difficult to maintain IPv4 and almost impossible to use it for a number of purposes (peer-to-peer, remote access to shared files on a NAS or connected home control systems, certain network games, etc.).

For Grégory Mounier of Europol, this can go further and "violates the privacy of many people who could be summoned in proceedings even though investigators are only interested in one suspect. In this context, only a near-total transition to IPv6 can be a sustainable response to this problem."

On the other hand, an operator buying IPv4 addresses from a foreign player takes the risk that its customers will be located outside France for many months and thus block many services.

 

Accelerating the transition to IPv6 is the only sustainable solution. Only a near-total mutation can allow content providers to do without IPv4.

Heat wave: why French DCs are holding up

on Thursday, 01 August 2019 Posted in Archives Rezopole, Archives GrenoblIX, Archives LyonIX

Heat wave: why French DCs are holding up

Heat episodes are not taken lightly by data center operators. In France, "we have gone from 40 degrees to 46 degrees in a few years. We have met the specifications of Spain," says Marie Chabanon, Technical Director of DATA4 Group.

 

In order to counter any heat stroke, the datacenters' resistance to temperatures has increased " The great fear is the domino effect [...] If all or part of the cold infrastructure has problems, it affects the rest of the equipment. And if the refrigeration unit stops, it's the worst thing that can happen to us with the complete power outage," added Fabrice Coquio, Interxion's Managing Director. A risk also linked to the quality of RTE or Enedis' electricity distribution. "We must anticipate a risk of electrical loss or incident," explains Marie Chabanon.

 

But data center operators have a secret boot to fight this domino effect. "Data center electrical systems are built to be 100% operational. However, this is never the case. The consequence is that in the event of a load, such as a higher cold demand, we have unallocated power that we can use," explains Fabien Gautier of Equinix. This is called capacity redundancy.

 

Especially since the densification of computing power per unit of space in recent years, with the democratization of virtualization, has led to more consumption and more heat. "With 14 or 15 kvA berries, we cause hot spots, which are more sensitive to heat waves," explains Fabien Gautier. The work of urbanizing the IT architecture deployed in the rooms is therefore essential. "Our work is therefore the urbanization of the rooms. If they were completed on the fly, that can be a problem," he adds.

This involves, among other things, load balancing. "Our data centers are designated with redundancies and a 50% load rate. The backup machines will be used to provide additional power" in the event of a heat wave, says Marie Chabanon. Nevertheless, it must be anticipated. "We must ensure that backup systems are ready to be operational, through maintenance and control actions on backup equipment."

 

The protection of data centers against heat also requires the installation of curative systems. "We installed water spray systems to water the roof equipment with water that is not too cold," says Fabrice Coquio.

And to be prepared for any eventuality in the early evening, the schedule of the technicians present on site has been modified. It is also necessary to warn customers so that they are careful.

 

Recent advances in hardware strength and data center design have made it possible to increase the temperatures in server storage rooms. "The idea is that the lower the PUE (Power Usage Effectiveness), the better it performs. Ten years ago, we used to make datacenters where it was difficult to achieve a PUE of 1.6. Today we are at 1.2 and we are getting closer to 1, which represents 20% savings by playing on the temperature and energy performance of the new equipment," says Marie Chabanon. As a result, the cooling system now focuses on machines with forced air. There is no longer any need to refrigerate entire rooms.

"We are seeing an evolution in the design of indoor temperature according to the recommendations of the Ashrae (American Society of Heating and Ventilating Engineers). The idea is to work well with much higher temperature ranges. We have gone from 20 to 22 degrees to 18 to 27 degrees," she adds. Since 2011, these standards have been raised: they recommend blowing at 26 degrees on the front panel on indoor equipment. "The humidity level was also modified [...] In 2008, it was between 40 and 60%. It is now 70%," says Fabrice Coquio.

 

This will limit cooling costs without affecting the resistance of the installations. A critical point in hot weather.

History and impact of IXP growth

on Friday, 26 July 2019 Posted in Archives Rezopole, Archives GrenoblIX, Archives LyonIX

History and impact of IXP growth

It is 1990: the Internet has a few million users and the first commercial companies have recently adopted this new distributed infrastructure.

 

The routing of network traffic from one region to another generally depends on the major transit providers (level 1). These levels 1 are at the top of the hierarchy, composed of a few thousand existing AS, forming what is called the network of networks.

 

A lot has changed since those early days, when small ASs paid the biggest for connectivity. This dependence on intermediaries has resulted in transit costs, indirect routes, long round trip times and a general lack of control over the quality of service. The bypassing of intermediaries by direct peering interconnections became the obvious answer, and Internet Exchange Points (IXPs) then appeared as the default solution for establishing connections.

 

Between 2008 and 2016, the number of IXPs and members almost tripled. At the same time, accessibility via these facilities has stagnated at around 80% of the announced address space (IPv4) while resilience has increased due to increasing redundancy.

 

In almost all regions, particularly in Europe and North America, IXP members have grown richer with an increasing number of members and greater accessibility. However, the regional ecosystems were distinct. For example, European IXPs had the largest number of members but the smallest AS (in terms of accessibility), Asia-Pacific was at the opposite extreme.

 

This growth raises the question of the observable impact of IXPs on the Internet. To answer this question, Queen Mary University in London, in collaboration with researchers from Roma Tre Univ, the GARR Consortium and the University of Tokyo, extracted a large collection of traceroutes covering the same period and identified IXPs crossed.

 

The IXPs have had a clear impact on reducing the average length of access paths at AS level, particularly for large (hypergiant) global networks. Given that these networks are traffic-intensive, it is likely that a large proportion of Internet traffic has benefited from a substantial reduction in the number of AS crossed.

 

They have also clearly helped to bypass level 1 transit providers. However, their impact on reducing the number of transit links (not necessarily level 1) visible on the route is more moderate.

 

Despite these changes, a clear hierarchy remains, with a small number of networks playing a central role. It is interesting to note that there is a small group of very central networks, regardless of whether the paths cross an IXP or not.

 

In addition, the Internet hierarchy has changed: large central networks have reduced their use of public peerings while IXPs have been adopted by smaller and less central ASs. This is probably due to the increasing popularity of private network interconnections (NIBPs), which are generally favoured by AS when large volumes of traffic are exchanged.

 

Overall, the increase in the number of IXPs since 2008 has had a clear impact on the evolution of the Internet, shortening paths (mainly) to hypergiants and reducing dependence on Tier 1 transit providers.

 

The results must be interpreted in the light of the constraints of existing data, and there are a number of areas where work is possible. For example, topological data are independent of traffic volumes and total visibility on the Internet is impossible to achieve.

 

In addition, content distribution network (CDN) redirection strategies are not included in the traceroutes; it is assumed that accounting for the increasing traffic volumes delivered by these networks would likely support these conclusions.
