Abstract

A system that utilizes data over cable service interface specification (DOCSIS) over passive optical networks is disclosed. An example system includes core system in a passive optical network (PON), comprising a memory; and one or more processors configured to generate a downlink (DL) data stream comprising optical signals, in compliance with a data over cable service interface specification (DOCSIS); and provide the optical signals containing DL data to a network component in the PON over an optical fiber coupled between the core system and the network component. In some embodiments, the core system is located at a head end equipment at the internet service provider's facility. However, in other embodiments, the core system can have a distributed architecture, with a part of the core system located at the internet service provider's facility and a different part of the core system located at a different location.

First claim

What is claimed is:

1. A core system in a passive optical network (PON), comprising:
one or more processors;
a memory including instructions comprising operations, for execution via the one or more processors, to:
generate a downlink (DL) data stream comprising optical signals, in compliance with a data over cable service interface specification (DOCSIS); and
provide the optical signals containing DL data to an output terminal associated therewith that is configured to couple to a network component in the PON over an optical fiber coupled between the core system and the network component;

a core component configured to perform network functions comprising media access control (MAC) and upper layer processing associated with the DL data, wherein the network functions includes generating DOCSIS data packets based on the DL data, via the one or more processors, utilizing the MAC and upper layer protocols in DOCSIS; and
a PON component coupled to the core component, and configured to perform network functions comprising physical layer processing associated with the DL data, wherein the network functions includes receiving the generated DOCSIS data packets from the core component over an interface between the core component and the PON component and converting, via the one or more processors, the received DOCSIS data packets into the DL data stream comprising the optical signals, utilizing PON standards.

2. The core system of claim 1 , wherein the PON component is further configured to receive an uplink (UL) data stream comprising optical signals comprising a UL data from an output terminal associated therewith that is configured to couple to the network component, and perform network functions comprising physical layer processing associated with the UL data, wherein the network functions include converting the optical signals comprising the UL data into DOCSIS data packets, utilizing the PON standards and providing the DOCSIS data packets to an input terminal associated therewith that is configured to couple to the core component over the interface between the core component and the PON component.

3. The core system of claim 2 , wherein the core component is further configured to receive the DOCSIS data packets comprising the UL data from an output terminal associated therewith that is configured to couple to the PON component, and perform network functions comprising the MAC and upper layer processing associated with the UL data, wherein the network functions includes processing the DOCSIS data packets, utilizing, via the one or more processors, the media access control (MAC) and upper layer protocols in DOCSIS.

4. The core system of claim 1 , wherein the interface between the core component and the PON component comprises an Ethernet interface.

5. The core system of claim 1 , wherein the network functions associated with the core component is virtualized.

6. The core system of claim 1 , wherein the core component is located at a headend equipment of the PON and the PON component is located at a street node of the PON.
