Abstract
Ethernet wide area networks and methods are disclosed. A disclosed example Ethernet wide area network includes a first network Ethernet switch having a first network interface and a first service interface. The first service interface is to communicate with a first local area Ethernet switch. The network also includes a second network Ethernet switch having a second network interface and a second service interface. The second service interface is to communicate with the second local area Ethernet switch. The network also includes a root node network Ethernet switch having a third network interface to communicate with the first network interface with the first network Ethernet switch and a fourth network interface to communicate with the second network interface of the second network Ethernet switch. The first, second, third and fourth network interfaces are to route packets from the first local area Ethernet switch to the second local area Ethernet switch without recognizing subscriber LAN MAC addresses associated with either the first or second local area Ethernet switches.
