Optical line terminal (OLT) system

A non-transitory machine-readable medium embodying instructions that, when executed by a machine, allow the machine to perform a method for providing an optical line terminal (OLT) system for a passive optical network (PON), the method comprising:

• mapping a plurality of logical identifiers of each of a plurality of PON ports to a plurality of tunnel identifiers, wherein each of the plurality of tunnel identifiers comprises a concatenation of a PON port identifier of the mapped PON port of the plurality of PON ports and a logical identifier index generated from the mapped logical identifier of the plurality of logical identifiers, and the OLT system is coupled to a plurality of optical network units via the plurality of PON ports, the OLT system being coupled to at least two of the plurality of optical network units via at least one of the plurality of PON ports;
• receiving, by a first device, a downstream data item from a network;
• determining, by the first device, one of the plurality of tunnel identifiers that corresponds to the downstream data item;
• appending, by the first device, the one of the plurality of tunnel identifiers to the downstream data item;
• and
• transmitting, by the first device over an Ethernet interface to a second device, the downstream data item including the appended one of the plurality of tunnel identifiers.

An optical line terminal (OLT) system for a passive optical network (PON), the system comprising:

• a processor that is communicatively coupled to an OLT Medium Access Control (MAC) device and a switch device, wherein the processor is operative to:
• map a plurality of logical identifiers of each of a plurality of PON ports to a plurality of tunnel identifiers, wherein each of the plurality of tunnel identifiers comprises a concatenation of a PON port identifier of the mapped PON port of the plurality of PON ports and a logical identifier index generated from the mapped logical identifier of the plurality of logical identifiers, and the OLT system is coupled to a plurality of optical network units via the plurality of PON ports, the OLT system being coupled to at least two of the plurality of optical network units via at least one of the plurality of PON ports;
• the switch device, wherein the switch device is communicatively coupled to the OLT MAC device via an Ethernet interface;
• and
• the OLT MAC device, wherein the OLT MAC device is communicatively coupled to the plurality of PON ports and the OLT MAC is operative to:
• receive a plurality of upstream data items over each of the plurality of PON ports, wherein each of the plurality of upstream data items comprises one of the plurality of logical identifiers;
• replace each of the plurality of logical identifiers of each of the plurality of upstream data items received over each of the plurality of PON ports with each of the plurality of tunnel identifiers mapped to each of the plurality of logical identifiers of each of the plurality of PON ports;
• and
• transmitting, over the Ethernet interface to the switch device, each of the plurality of upstream data items comprising each of the plurality of tunnel identifiers.
