Virtual Leased Line

Low-latency virtual MPLS-based point-to-(multi)point

MPLS VLL (Virtual Leased Line) is a great technology to connect multiple LANs over a WAN network. Organizations often use the MPLS Transport technology to create a Transport network in order to connect multiple offices and/or datacenters.

One of the great use cases for MPLS Transport however is that is allows not to only connect your own networks together, but also allows to connect you with external parties, for instance a supplier, in order to exchange traffic over a shared VLAN. As NL-ix is datacenter neutral, the VLAN can be shared in between datacenters operated by different operators.

The NL-ix service provides cost-effective managed capacity with a dedicated Ethernet connection between two datacentres with NL-ix PoPs with the resilience of MPLS technology (automatic rerouting). As well as low latency, this highly flexible service offers extremely high availability due to the multiple backbone paths and fast re-routes built into the NL-ix interconnection fabric.

Virtual Leased Lines can be delivered over tagged as well as untagged ports. In case of a point-to-point topology using untagged ports, the services offers max transparency with unlimited MAC addresses, dot.1 Q-in-Q, mac-in-mac, MPLS and jumbo frames.

Technical features

  • Transparant: allows unlimited MAC addresses, dot.1q, Q-in-Q, mac-in-mac, MPLS and jumbo frames;
  • Secure: delivers a completely private circuit where traffic cannot be seen by other customers or even NL-ix;
  • Any distance: NL-ix hides the distance between endpoints and repeats the signal along the way if needed.

Transport Topologies

Point-to-Point (VLL - tagged or untagged) is a direct connection between two ports in the network

Point-to-Multipoint (multiple VLL - tagged) connects a single location to multiple end-points. Every end-point is connected with it's own VLAN. A single port can be used for the central connection

Any-to-Any (VPLS - Virtual network) topology connects multiple ports on a single VLAN. This allows easy communication between all ports on the VLAN

Key Features

  • Pan-European PoPs
    NL-ix operates a purpose-built, resilient, pan-European Layer 2 Ethernet fabric, which interconnects around 100 datacenters in the most important European metropolitan markets. VLLs can be connected to ports at any point on the NL-ix fabric

  • Unlimited VLANs
    The NL-ix MPLS Transport bundles allow for as many VLANs as desired. This means that you simply pay for the bandwidth capacity without an incremental charge per VLAN.

  • End-to-End management
    NL-ix builds, manages and monitors the end-to-end connection for you, offering availability guarantees, and 24/7/365 NOC monitoring and support

  • Flexible capacity
    You can burst up to your maximum port speed without overbooking on pre-reserved capacity

Use Case:

One Port – Multiple services

NL-ix combines peering, transit and layer 2 transport services over 1 port... enabling you to save money on patch cables and ports and simplifying manageability.

By combining peering, transit and layer 2 transport services over 1 port we enable you to save on the monthly cost of patch cables and ports in use. Multiple services over 1 port also means a single invoice and easer manageability. We also give you more and easier insight into the usage of your port(s) through our improved myNL-ix portal. Through this customer portal you can easily view the usage per service on your ports.

Using NL-ix means lowering your costs, simplified administration and improved insight.
