An Ethernet exchanger is coupled to two or more Ethernet networks to exchange information among the two or more Ethernet networks using virtual circuits. A first Ethernet network is associated with a first carrier and a first port of the Ethernet exchanger. A second Ethernet network is associated with a second carrier and a second port of the Ethernet exchanger. Network information of the first Ethernet network and network information of the second Ethernet network are provided by the respective first carrier and the second carrier and stored in a database. A virtual circuit is provisioned to interconnect the first Ethernet network and the second Ethernet network based on a partnership between the first carrier and the second carrier and based on the stored information about the first network and the second network. The virtual circuit is associated with the first port and the second port. The stored information about the first network or the second network is reusable for subsequent provisioning of other virtual circuits associated with the first carrier or the second carrier.
