An AMS-IX Story

Back in 2015, AMS-IX tested a series of DWDM Equipment under the name of Data Centre Interconnect (DCI) from different vendors in an effort to optimise the Core network.

On September 1st 2016, Henk Steenman (CTO at AMS-IX) published a blogpost about choosing the Huawei OSN range. As Henk states in his blog: "DCI solutions have two great benefits for us and our members and clients. First of all, this solution will bring down implementation time for additional bandwidth. Secondly, it will help us reduce costs in comparison to the use of our current solution: dark fibre."

14 PoP’s in 24 months

Less than 2 years after starting this implementation, on the 2nd of August 2018, the last PoP location in the Amsterdam Area has been equipped with the Huawei OSN Range, finalising this massive migration. A true moment of pride for the entire AMS-IX family!

To reflect what we did during these 22 months:

  1. Migrated a total of 12 PoP Locations
  2. Installed an additional 2 PoP Locations
  3. Performed 8 backbone upgrades
  4. Reduced dark fibre usage from 288 pairs to 30 pairs
  5. Partially migrated management network to DCI connections
  6. Partially migrated from LR4 to SR4 optics

In the end, a lot of costs have been saved by reducing our dark fibre usage by 90%, the ability to use SR4 optics and the reduction of time spent on expanding our core network.

To visualise it all, below is our Network Topology of 2015:
