Abstract
Logical ports allow multiple customers to be connected to and to receive different services over a common physical port of a packet forwarding device. Such logical ports allow for customer separation and may be created based on VLAN ID and MPLS labels. In one embodiment, each service provided via a packet forwarding device is associated with a unique logical port. The logical port may span multiple physical ports.
