Abstract:
A network node includes a first port and a second port, the second port being operable to carry a first type of data traffic over a main physical interface, the first type of data traffic including Layer 2 services. The second port is operable to simultaneously carry a second type of data traffic over a sub-interface of the main physical interface. The second type of data traffic consisting of Layer 3 services that include point-to-point (P2P), point-to-multipoint (P2MP), and multipoint services.
