Closed User Group

Closed User Group

A Closed User Group (CUG) is an interconnection environment for a specific group of parties that have a common interconnection requirement. Typically, one of these requirements is that interconnection is realised outside of the public Internet.

How it works

With the AMS-IX Closed User Group solution, you can exchange IP traffic with two or more other participants over a dedicated VLAN.

This way, you can create a private interconnection environment and directly connect with your suppliers or customers at different colocations.
