Adaptive Transit combines the three platforms (Peering, Open Peering and Joint Transit) onto a single port using two VLANs: the NL-ix Peering VLAN and a Transit VLAN.

The NL-ix Peering VLAN provides the Peering service, the Transit VLAN is used to setup BGP between the customer router and the Transit routers and exchange traffic between them.

NL-ix offers us the opportunity to send traffic with different VLANs and with different BGP communities without the hassle of managing prefix lists.

Frequently asked Questions

What is the main difference between Adaptive Transit and NL-ix Transit?

Adaptive Transit empowers users with complete control to route and filter their traffic according to specific requirements by using the NL-ix Route Server Configurator (Peering) or BGP communities (Peering + Open Peering) , while NL-ix Transit is a fully managed service where NL-ix pre-configures the optimal routes, saving users the trouble of difficult BGP configuration.

How does Adaptive Transit offer build-in redundancy?

Peering and routing prefixes are redundantly covered within the Transit sessions. With multiple sessions to geographically divers routers and Route Servers, Adaptive Transit offers built-in redundancy.

In total, Adaptive Transit provides five BGP sessions:

  • Primary Joint Transit router
  • Secondary Joint Transit router
  • Open Peering router
  • Primary NL-ix Route Server
  • Secondary NL-ix Route Server

Why is Peering preferred over IP Transit?

When a network router receives a request, it consults its routing table to determine the shortest path to the requested information. Based on the available information, the router forwards the request to the next router in its path towards the end destination. Each router makes its routing decisions based on its own knowledge and information. If there is a direct Peering relationship with the destination network, it will be utilised. However, if such a direct link is absent, the data is sent through intermediary routers and networks until it reaches its final destination. This process is commonly referred to as IP Transit. It's important to note that each router along the way introduces processing time, leading to increased latency and uncertainty about the path the data will take. Regardless of how your business is connected to the Internet, you will inevitably rely on IP Transit to some extent. However, to achieve a more predictable and direct path, it is advantageous to leverage direct peering relationships whenever possible, minimizing the number of hops and reducing latency.

What are the available bandwidths for Adaptive Transit?

Adaptive Transit is available from 100 Mbps up till 100 Gbps in flat fee but there are also options for a metered variant. With link aggregation multiple physical connections can be bundled into a single logical connection.
