Private Interconnect

A Private Interconnect (PI) enables direct traffic exchange between two networks over a dedicated VLAN on the AMS-IX Chicago infrastructure. The Private Interconnect VLAN can be implemented either on a dedicated port or on an existing port with (802.1) Q-tagging.

PI service description & features

A PI connection has two parties:

  • Initiator - The Initiator is the AMS-IX Chicago contact point for the VLAN. The “ownership” of the VLAN lies with the Initiator.
  • Participant - The other party is termed the Participant.

Both Initiator and Participant must be AMS-IX Chicago connected networks.


  • See ISP Unicast service description.
  • AMS-IX will assign a private VLAN, in the form of a VPLS instance.
  • AMS-IX will configure a port in the PI VLAN and assign it to the Initiator.
  • AMS-IX will configure a port in the PI VLAN and assign it to the Participant.

Technical service:

  • AMS-IX Chicago does not assign IP addresses in the PI LANs. This is up to the participating parties.
  • Customers may connect to a PI using a dedicated port, or using an existing port with a chosen 802.1Q tag.
  • We do not allow multiple MAC address on the port. So traffic from PI LANs should be from the same MAC address.
  • Both parties can contact AMS-IX NOC in case of problems. 
  • In case of problems the following information should be supplied to the NOC:

- Names of both parties involved.

- PI VLAN identification.


  • See the ISP Unicast service description.
