Private Network Interconnect

A Private Network Interconnect (PNI) enables direct traffic exchange between two networks over a dedicated connection on the CNX infrastructure. A Private Network Interconnection can be implemented either:

  • on a dedicated port or
  • on an existing port with (802.1) Q-tagging or
  • physical cross-connection via fiber optics.

A virtual PNI connection has two parties, both must be CNX connected networks. A port with 802.1Q tagging can participate in more than one PI. A physical PNI connection can be established by any two parties co-locating at CNX.

VLAN based PNI

  • CNX will assign a private VLAN
  • CNX will configure both port in the PI with the same VLAN

Physical PNI

  • CNX can cross connect from ODF to equipment hosted at CNX within the same location
  • CNX can cross connect between hosted equipment within the same location

Technical service

  • CNX does not assign IP addresses in the PI LANs. This is up to the participating parties
  • Customers may connect to a PNI 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, traffic from PNI LANs should be from the same MAC address
  • Both parties can contact CNX NOC in case of problems
