History and impact of IXP growth

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

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.

Arcep: Open Internet

on Thursday, 11 July 2019 Posted in Archives Rezopole, Archives GrenoblIX, Archives 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.

The Internet network is drowning

on Tuesday, 02 July 2019 Posted in Archives Rezopole, Archives GrenoblIX, Archives 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".

Sign up for yALPA 002 !

on Tuesday, 25 June 2019 Posted in Archives Rezopole, Archives GrenoblIX

Sign up for yALPA 002 !

After a first meeting on January 29th, the second is planned for July 2th at Challes-les-Eaux.

 
Theme: HSBB in the Alps

Departments concerned: 38; 73; 74 and 01 (South Jura) with a focus on tourist areas (ski resorts, hotels).

 
Observation:

Broadband needs are exploding with the advent of "Over The Top" (OTT) networks and the strong growth of services such as Amazon Prime Video, Netflix, OCS, MyCanal...
Initial observations between the 2017 and 2018 Christmas holidays show a +60% increase in the throughput consumed in hotels and hotel residences. For these establishments, connections in Mbs will soon no longer be enough and requests in 1, 2, 3 or even 4 Gbs are beginning to arrive.

 
Work in synergy:

From now on, it is essential for telecom and Internet operators to organise themselves in order to be able to respond effectively to this need, which was yesterday emerging and is now very present.
This is the objective of yALPA! We must encourage the actors of Very High Speed deployment to meet and get to know each other better in order to consider future collaborations rather than planning, each on its own, investments in the same places.
The local DSPs (38, 73 and 74) do part of the work, but simply changing departments is complicated. Let us bet that by exchanging informally, a collective intelligence will make it possible to accelerate the arrival of really Very High Speed offers in the Alps (resorts but also valleys and plains).
It is understood that the results of these initial yALPA discussions will not have immediate effect. However, in the more or less short term, the problems currently encountered in terms of HSBB in tourist areas can be solved.

 
Morning program (9:00 am - 12:00 pm):
  • welcome, coffee, pastries
  • round table discussion: presentation of each participant
  • Transalpinet presentation (study by Rezopole)
  • room for improvement:
    • common carto tool.... Should we start where we wait another 10 years?
    • new backbone offers from external operators
    • territories without POPs
 
Registrations:

from Samuel Triolet (director of Rezopole) : striolet (from) rezopole.net

 
Practical informations:

See you on July 2nd at 9:00 am at Hub des Alpes (salle Altitude 193) - 37 avenue des Massettes, 73190 Challes-les-Eaux.

Auvergne : HSBB acceleration

on Thursday, 02 May 2019 Posted in Archives Rezopole, Archives GrenoblIX, Archives LyonIX

Auvergne : HSBB acceleration

In 2013, the initial public-private partnership contract for the installation of Very High Speed Internet in Auvergne was recently renegotiated. The departments of Puy-de-Dôme, Cantal and Allier voted for this renegotiation. The President of the Auvergne-Rhône-Alpes Region, Laurent Wauquiez, has therefore signed a new agreement with Orange to ensure the development of the HSBB in the region.


Indeed, the digital coverage of the territory will gain 3 years. By 2022, 436,000 plugs will be deployed, 120,000 more than under the previous contract. Thus 84% of Auvergne will be eligible for fibre within two years.
This will allow the Region and the various local authorities to save 137 million euros on the deployment of optical fibre. Overall, the Auvergne-Rhône-Alpes Region has invested 180 million euros in this project, which represents 50% of the public-private partnership.

When Facebook wants to surround Africa

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

When Facebook wants to surround Africa

In the Wall Street Journal the company decided to talk about this disproportionate operation, called "Simba". Very few details have so far been revealed about the project. We only know that it would be connected to existing access points, particularly on some beaches on the east, north and west coasts.

Surrounding Africa with a gigantic submarine fibre optic cable would allow almost the entire population to enjoy the Internet. Facebook knows that to extend, it must absolutely attack this continent inhabited by more than 1.2 billion people and which is not yet very well connected to the rest of the world. This is due to infrastructure that is still under development and completely uncovered areas. So if several million Africans could connect to the Internet tomorrow and create a Facebook, WhatsApp or Instagram account, the social network would save a lot of users in a very short time.

However, there would not yet be a signed agreement for the installation of this huge cable. And this is not the first time Facebook has talked about installing an underwater cable to connect the world. Facebook was pulling a transatlantic cable over 6,500 kilometers long, Marea, in 2017 with the help of Microsoft. The installation began in 2016 and provided a stable connection in 2018 by connecting Virginia Beach, United States to Bilbao, Spain.

Test your domain name!

Test your domain name!

Revolution for the Domain Name System! To maintain the stability of hosted domain names since the introduction of the EDNS standard in 1999, several DNS servers have simply implemented patches. However, since February 1, patches that do not comply with the EDNS update have been removed. This can therefore lead to malfunctions or even the deletion of domain names hosted on these servers.

A tool is available on the DNS Flag Day website to test your domain name. "This change will make most DNS operations slightly more efficient and will also allow operators to deploy new features, including mechanisms to protect against DDoS attacks," says the dedicated site.

Fibre: ADLC rejects any splitting of Orange

on Monday, 04 February 2019 Posted in Archives Rezopole, Archives GrenoblIX, Archives LyonIX

Fibre: ADLC rejects any splitting of Orange

Submitted last autumn by the Association of Alternative Telecommunications Operators, the request for an opinion to separate Orange's retail and infrastructure sectors into two separate entities was rejected on 30 January by the French Competition Authority. Indeed, the competition police do not consider it useful to give a favourable follow-up to the study of this referral for an advisory opinion.


The 45 operators that make up the AOTA protest against "repeated problems of access to the Civil Engineering of the Orange operator inherited from the national public domain of telecommunications, itself used by Orange to operate its copper network and constitute a passive shared fibre network currently unavailable in activated mode for competition."


However, the association does not intend to stop there, since it now plans to call on Brussels to defend its positions: "the association takes note of this decision by the independent administrative authority responsible for protecting consumers, whether residential or economic, from unfair practices on the part of private interests. It now also intends to refer the same matter to the European Union in order to obtain its opinion and, if necessary, to take the necessary corrective action to ensure that competition is conducted in a healthy and fair manner on the French telecommunications market."

The largest datacenter in Lyon

on Thursday, 24 January 2019 Posted in Archives Rezopole, Archives GrenoblIX, Archives LyonIX

The largest datacenter in Lyon

Inaugurated on January 15 by the national operator Jaguar Network, the last datacenter of the Lyon metropolitan area was built within the Biopark of the 8th arrondissement. Known as "Rock", this datacenter is also the largest in Lyon with more than 4,000 m² and 800 computer bays.
This project, supported by the Auvergne-Rhône-Alpes region, now hosts IT projects in the health and industry 4.0 sectors after only twelve months of construction.

However, the building has a particular feature for a datacenter: "The aesthetics of the building has been a constraint imposed by the French building architects: Rock is located within the perimeter of the Édouard Herriot Hospital, built a century ago by the architect Tony Garnier and listed as a historic monument. Thus, to comply with the specifications imposed by the French administration, it was mandatory to equip the building with windows, walled by breeze blocks since they were totally useless for computer rooms...!" notes Pierre Col in an article in ZDNet.

The operation of the infrastructures of this new datacenter has been maximized by using, for example, artificial intelligence. "An application developed by Jaguar Network teams proactively manages the installations in order to perform preventive maintenance to maximize availability. This is how technologies based on Big Data and Machine Learning are integrated into the spectrum boxes whose mission is to predictively detect any incident," says Jaguar Network.
In addition, a team is permanently present on the site "This guarantees local support to customers for the simplified operation of their IT equipment. A technician can work on any server hosted in the heart of the building in less than 10 minutes," explains the operator and cloud host.

To demonstrate its commitment to investing in digital transformation, the company has also created a network of more than 80 km of dark fibre network. This allows any company in Lyon's metropolitan area to be connected directly by dedicated and secure cables. "A dedicated 100 Gbps network will be available from February 2019 to provide the highest connection speeds available in France for businesses," says Jaguar Network.
