Transport Services

Optical and logical transport services

Fine-grained datacenter footprint

Most companies today need transport capacity between colocation facilities, whether it is for connecting core equipment between markets or reaching and connecting with remote suppliers, customers or partners. Because the NL-ix fabric covers all of Europe’s most important datacenters we can offer a complete suite of Layer 2 transport services, and where we don’t have a Point of Presence we can quickly and easily extend these services even further afield. 

Transport Technologies

The key decision when selecting a Transport technology is whether you want a Dedicated (optical) or Ethernet (logical) solution.

  • Dedicated Transport uses optical equipment to create a connection between two or more locations with a fixed path and predictable latency.  Dense Wavelength-Division Multiplexing (DWDM) doesn’t use switches in the NL-ix network and is completely transparent, allowing you to add VLANs as required. For resilience, path redundancy is recommended.

  • Ethernet Transport uses switching equipment to create a logical connection between two or more locations based on Multiprotocol Label Switching (MPLS). Because a switching network is used, traffic can be rerouted across the underlying fiber infrastructure if any issues arise, providing automatic path redundancy.

Dedicated (Optical) Ethernet (Logical)
Static route Highly flexible
Less scalable Easy scalable
Predictable latency Fast provisioning
Predictable jitter Fast rerouting
Dedicated bandwidth High availability
Managed solution Managed solution

Transport Topologies

Point-to-Point is a direct connection between two ports in the network

Point-to-Multipoint (or Star) connects a single location to multiple end-points.  For example, this could be a central site connected to smaller satellites, or a reseller that uses the NL-ix network to reach multiple end-users.  A single port can be used for the central connection

Cloud topology connects multiple ports on a single VLAN. This allows easy communication between all ports on the VLAN

Use Case:

Linking the most important datacenters in Europe

Whether you need to connect equipment in two redundant datacenters or reach suppliers or partners in sites you don’t have a presence in, most companies have a need for transport capacity between datacenter facilities.

NL-ix offers transport capacity services between the close to 100 neutral datacenters where it has a presence, and can use partners to connect other non-datacenter locations to an NL-ix covered datacenter.

We offer different transport technologies (DWDM, MPLS, VLL and VPLS) in point-to-point and point to multi-point topologies, suitable for all different needs. No sure what you need or want to know more? Please don't hesitate to contact us!
