Abstract
An Ethernet Tree (E-Tree) service is described instantiated on an Ethernet switch and in an Ethernet network. The E-Tree service is implemented using Private Forwarding Groups (PFGs), asymmetric Virtual Local Area Networks (VLANs), virtual switches, and port configurations. The use of PFGs in addition to asymmetric VLANs provides higher levels of security in the described E-Tree systems and methods. The E-Tree systems and methods also can utilize Access Control Lists (ACLs) at Network-Network Interfaces (NNIs) for controlling unknown unicasts from reaching wrong ports. The E-Tree systems and methods can also seamlessly interoperate with packet switches using an IEEE 802.1Q-2011 approach.
