Abstract
A method of routing traffic to customer premises devices (CPDs), each CPD being reachable via a dedicated customer interface (DCI) from among a plurality of DCIs grouped into clusters included in respective outside plant units (OPUs). Packets destined for the CPDs are received. A destination DCI and a destination OPU for each packet is determined. The destination DCI for a particular packet destined for a particular CPD is determined by identifying the DCI via which the particular CPD is reachable. The destination OPU for the particular packet is determined by identifying the OPU that includes the destination DCI. For each particular OPU that is the destination OPU for one or more packets, the packets are buffered and transmitted via an interface for the particular OPU. For each particular DCI that is the destination DCI for one or more packets, tagging each packet with an indication of the particular DCI.
