In early September, LyonIX moved into Jaguar Network's new ROCK datacenter. Then, on September 16th, LyonIX also moved into the Carrier Hotel in hosTELyon.
These new PoPs are both connected to the rest of the infrastructure of the exchange node via 10G links.
You can now connect to these points of presence and have access to all the services offered by Rezopole.
Rezopole is pleased to invite you on Thursday, September 26th to the next IXPloration organized in its offices at 16 rue de la Thibaudière, 69007 Lyon.
This completely free event will be an opportunity for you to discover LyonIX, the IXP / NAP of Lyon.
Thus will be detailed during this morning:
- the IXP part, which improves Internet exchanges between users in a territory, reduces telecom costs, and secures and optimizes the network thanks to the multiple routes offered.
- the NAP part, which provides connected members with direct access to the operators present and their offers. We buy or sell any type of Telecom service with great flexibility.

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.

LyonIX's InterIXP peering has been strengthened in Switzerland, where a new link has been established with the SwissIX exchange point. All members of this exchange node, spread over the cities of Zurich, Basel and Bern, can exchange traffic with LyonIX members through the announcements available on the route servers.
After the CIXP, SwissIX is the second IXP to which LyonIX is connected in Switzerland. This new interconnection makes it possible to increase the number of Swiss players that can be reached via LyonIX, as confirmed by the establishment of stable traffic since the link was set up.
The Rezopole team is at your disposal for any information regarding this new interconnection. Also check the Rezopole weather-map to discover the other regional and national inter-IXP links!

In this document, you will find a retrospective of our actions and events in Rezopole over the past year. Among the information to remember: the opening of a new IXP in Annecy, named AnnecIX, with two members already in place; the arrival of new members such as the major content provider Akamai; the achievement of Datadock certification allowing support for the training courses offered by Rezopole; and of course the must-see Aperezo events held in Grenoble last June and November. Much more information is detailed in this new annual report.

The Compagnie de Chauffage Intercommunale de l'Agglomération Grenobloise (CCIAG) is a local energy operator for the production and distribution of heat and related services in the metropolitan area. For nearly 60 years, the company has been facilitating and supporting urban development and renewal for an attractive, socially responsible and sustainable metropolis. Thanks to its innovative approach, it offers an ever greener energy mix to supply its heating network, the 2nd largest in France, currently 65% renewable and recovery energy, with a target of 100% by 2033.
Since February 1st, the CCIAG has been connected to the infrastructures of GrenoblIX, IXP / NAP of Grenoble.
"The opportunity to integrate GrenoblIX presented itself to us as we began to explore the Grenoble basin in search of operators that would allow us to increase our current external bandwidth to meet the company's growing needs as part of its digital transformation. At the same time, we were put in contact with the department in charge of Metronet (the dark fibre network of the Metro), which allows us to interconnect all our sites and connect to the IXPs in Grenoble at a lower cost.
The rental of a local loop, as well as the Internet access attached to it, has therefore been made obsolete by the use of Métronet for our MAN (Metropolitan Aera Network) on the one hand, and for the "last mile" to the transit operators present in the IXP DCs on the other hand.
In addition, our presence in the IXP will allow us to interconnect directly with local actors, and other LyonIX members, allowing us first of all to save even more on our future transit purchases, but also to reduce our latency times towards them.
In the end, we will have a better understanding of all aspects of the company's connectivity to the outside world, by becoming a LIR operator, and will no longer be dependent on the risks associated with a single operator."

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.
