Another thorn in the side of the digital infrastructure sector is customers' end connections to fibre optic cable. Indeed, there is growing discontent with the disruptions observed in the sharing points and the threat they pose to the sustainability of networks. Called upon to intervene more frankly, the Arcep is finally taking matters into its own hands to do something about the "noodle dishes".

At the Telconomics conference on 16th June, the Regulatory Authority said it was "extremely concerned" by the multiplication of these aberrations. To remedy this, the telecoms regulator has therefore published a "first roadmap" drawn up in consultation with the players in the sector. The objective is to give infrastructure operators the possibility to better control interventions on their networks. They will thus be able to report, or even deregister, unscrupulous subcontractors mandated by commercial operators.

Sébastien Soriano, President of the Authority, explains that the aim is to "prevent a few black sheep from destroying the highly professional work of most of the other subcontractors". A first step that will not settle all the questions, such as those of recruitment, the pricing of these interventions, or the differences in connection technologies between infrastructure operators and access providers.

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".

Published by Axians, the DataCenter 2018-2021 study, Which evolutions for your IT infrastructures, indicates that data centres will be managed mainly in a private cloud mode by 2021. More than half will need to integrate a data management model based on a hybrid cloud model.

When asked in 2018, nearly 80% of CIOs say they mainly manage On Premise infrastructures and nearly one-third manage private cloud infrastructures. By 2021, this trend will intensify as, contrary to popular belief, internal data centres will not disappear. Indeed, it is the technologies implemented that will evolve and allow these data centers to operate in Cloud mode.

Although more than half of companies are aware of the need to manage data in a public-private cloud mode, only 12% of respondents have a project to implement a hybrid cloud solution.

According to this study, the 4 main current challenges for IT Departments are security (73%), cost control (66%), regulatory compliance (60%) and the digitalization of business lines (52%). The technology that will have the greatest impact on data centers within three years will be cybersecurity in the face of business service automation. On the software side, VMware leads ahead of Microsoft and Red Hat. While on the cloud operators side, Microsoft is cited first ahead of OVH and AWS.

For the majority of the CIOs interviewed, they remain the technical and operational guarantors of the infrastructure or strategy and innovation. However, new roles are emerging such as private cloud resource providers driven by SLA or hybrid cloud operators.

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.

According to International Data Corporation, the consumption of suppliers of servers, storage solutions and network equipment and software accounted for 44% of sales in 2018. These investments are expected to increase by an average of 6% per year and represent $426 billion over the next three years. Investments by cloud and digital service providers are expected to grow the most to reach $105 billion (+9% per year on average). Purchases by providers of hosting and colocation services amounted to $67 billion, representing an average annual growth rate of 7%.

However, there is a wide disparity between regions of the world. Indeed, if the share of these investments in the United States should increase to 47% in 2022 (compared to 44% today), Western Europe's share will not change and will remain at 12%.

Interviewed by Pierre Col, the team of independent developers behind the "Damage to Networks" initiative explains why and how this solution came about.

 
The objective of this project is to enable everyone to report damaged network infrastructure (Internet, Telecommunications, electricity or gas) on the public highway. Indeed, once information on vulnerability points is collected, it is shared on the website dplr.fr and then relayed to the Twitter @ProjetDPLR account.

 
The idea of HPRD comes mainly from two facts. The first, the proposal of one of the contributors to create a collaborative map of the damaged sub-distribution cabinets. And the second, the observation - of these degradations by many people working in the networks - was of particular interest to operators. The development of "Damage to networks" thus makes it possible to identify damage in a transparent manner and thus initiate a follow-up of repairs.

 
If for the moment it is an Alpha version, DPLR will eventually allow operators to have additional eyes in the field. Indeed, the philosophy of the collective is that the tool should be accessible to as many people as possible: residents, citizens, administrations and operators. The approach is clearly a crowdsourcing approach.

Internet exchange points play a key role in the Internet ecosystem. Today, there are more than 400 of them in more than 100 countries around the world. IXPs offer a neutral and shared switch fabric where customers can exchange traffic with each other.
Simply put, an Internet exchange point can be considered a large level 2 (L2) switch. Each client network connected to the IXP connects one or more of its routers to this switch via Ethernet interfaces. Routers on different networks can establish peering sessions by exchanging routing information via BGP and then sending traffic via the Ethernet switch.
IXPs allow operators to locally interconnect one or more customer networks through their level 2 networks. This leads to a more resilient Internet, improves bandwidth usage and reduces the cost and latency of interconnections. To avoid the tedious implementation of bilateral peering sessions, most IXPs nowadays use route servers. This simplifies peering by allowing IXP clients to peer with other networks via a single BGP session to a route server.

Whereas in the early 1990s, IXPs were based on FDDI or ATM, today the standard interconnectivity service is based on Ethernet. However, the level 2 switch fabric of an IXP is also evolving, moving from simple Ethernet switches on a single site connected via a standard local area network to IP/MPLS protocol switches distributed over several sites requiring WAN connectivity over optical fibre.
As a result, with more locations and increasing bandwidth, the connectivity network becomes more efficient, flexible and scalable. It is therefore an important strategic asset for IXP operators.
It should be noted that although switch fabrics based on IP/MPLS are mainly used today, there are other approaches such as VXLAN. These methods, which do not change the basic topology of the architecture, may be deployed more often in the future.
It should also be mentioned that to improve the resilience of the IXP infrastructure, PXCs are increasingly being used between the client and PE routers. In the event of a failure or scheduled maintenance, the PXC can switch from the client router to a backup PE router.

Innovation is accelerated with disintegration, SDN, NFV and network automation. Indeed, these new technologies are increasingly being used in telecommunications networks and IXPs. However, as IXP networks are generally more localized with older infrastructure and services than telecommunications networks, they may be the ideal place to introduce new network concepts.
Optical media is making progress inspired by the automation and openness of network technologies and offers innovative, ultra-dense and efficient systems. Many IXPs deploy these technologies to increase capacity while reducing costs, ground space and power consumption.
The disintegration of routers is also widespread in DC. Instead of using routers based on bulky chassis, SDN-controlled, white label L2/L3 switches using more scalable leaf-spine technologies are preferred. The use of white labels with a configurable and hardware-independent NOS provides greater flexibility and allows IXP operators to select only the features they really need.
