Our network

The network is designed to provide a guaranteed 100% Internet service availability.

The services are delivered from the Autonomous Systems Number (AS) 57866 on a footprint of data centers in The Netherlands and the US. In both countries, we connect to tier-1 upstreams, strategic private peering partners and some Internet exchanges. Our network provides non-overbooked, high performance access to the Internet and directly to networks of cloud providers, such as AWS, Microsoft Azure and Google Cloud.

Fusix routing policy towards our customers is to provide the best routes that we have (not the cheapest). In addition, we go for stability: we prefer to set up a dedicated cross connect to a tier-1 provider and only use part of their routes, rather than connect to an Internet exchange where hundreds of members may or may not announce to us routes that they may or may not be allowed to announce. We have a selective peering policy and for stability reasons may choose to send traffic to other parties over a link that we need to pay for, instead of sending traffic to a peering link for free.

Full redundancy of backbone components

Our on-net locations are connected to the core routers in a form of a star, while all backbone components are deployed redundantly. This design provides 100% service availability and dramatically reduces the possibility of customer impact during network maintenance events or unplanned outages.

Each on-net data center is equipped with 2 physical Arista switches, each of which is connected to a core router. IP transit service is always delivered on two ports while VLL services are delivered to customers on 1 port per location. For VLL service, in order to achieve redundancy (or “protected VLL”), we can deliver two circuits that run totally independently of each other.

Within each pair of dark fibers, the two lines follow a different path regarding each other, which eliminates a risk of accidental damage of both lines at the same time.

The core routers are Juniper MX960 devices that are located – for service continuity reasons – in 2 separate data centers: Nikhef and euNetworks.

The result of the backbone design is the best service availability rate in the market.

IPv4 and IPv6

The Fusix backbone supports IPv6 and IPv4 natively and offers Internet services to both IPv4 and IPv6 networks using BGP (Border Gateway Protocol) or default routes.

Network Operation Center

Our network is managed by the Fusix Network Operation Center in The Netherlands, using a management platform that is deployed redundantly: one inside our own backbone and one independent from us. Most of the network configuration tasks – such as IP address prefix management – are automated, which allows the NOC staff to deliver and maintain customer-connections fast and without human errors.

Network supervision and monitoring are handled by consolidated open source diagnostic tools that produce fault reporting alarms and monitor physical connectivity and routing behavior for each customer connection.
