Virtual PON MAC Buffering for Fiber-to-the-Home Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing fiber-to-the-home implementation methods require physical installation and maintenance of Optical Network Units (ONUs) in each user's home, leading to complex operations, high labor costs, and resource wastage due to hardware and software upgrades, as well as inefficient troubleshooting and recycling processes.
Innovation Solution
A method and device that utilize virtual PON MACs and User Network Interfaces (UNIs) to preset corresponding relationships among buffer areas, allowing multiple virtual PON MACs to share resources and provide a service similar to fiber-to-the-home through copper wires, reducing the need for physical ONU installations and simplifying maintenance by centralizing functions within a single ONU device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If physical ONUs are installed in each user's home, then fiber-to-the-home service can be provided, but operation and maintenance complexity increases significantly
Solution Approach 1:
The patent merges multiple physical ONUs into a single ONU device by virtualizing the PON MAC layer. Multiple virtual PON MAC addresses are created within one physical ONU, allowing it to serve multiple users simultaneously. This consolidation eliminates the need for separate physical ONUs in each user's home, thereby reducing operation and maintenance complexity while maintaining fiber-to-the-home service coverage.
Solution Approach 2:
The patent creates virtual copies of PON MAC functionality within a single physical ONU. By implementing multiple virtual PON MAC addresses that behave like separate physical ONUs, the system provides individualized service to each user without requiring separate physical devices. This virtual copying approach maintains service adaptability while simplifying the physical infrastructure.
2Adaptability or versatility
If physical ONUs are deployed in each user's home, then individual user service is enabled, but labor costs for installation and maintenance increase
Solution Approach 1:
The patent combines multiple user service capabilities into a single physical ONU through virtual PON MAC addresses. Each virtual PON MAC can be independently configured and managed for individual users, but all share the same physical hardware. This approach maintains individual user service capability while eliminating the need for technicians to physically install, maintain, and recycle separate ONUs at each user location, significantly reducing labor time and costs.
3Adaptability or versatility
If traditional ONUs are used in each user's home, then hardware resources are allocated per user, but resource wastage occurs during upgrades and recycling
Solution Approach 1:
The patent merges the hardware resources of multiple potential ONUs into a single shared physical ONU. The virtual PON MAC addresses allow the system to allocate and manage hardware resources dynamically among multiple users without requiring dedicated physical hardware for each. This eliminates resource wastage during hardware upgrades and recycling, as there is only one physical device to maintain and update regardless of the number of users served.
Solution Approach 2:
The patent makes the single physical ONU universal by enabling it to perform the functions of multiple ONUs through virtual PON MAC addresses. The same hardware resources can be allocated to different users as needed, providing per-user resource allocation without requiring separate physical hardware for each user. This multi-functionality approach prevents hardware resource wastage while maintaining adaptability.

AI summary
Provided are a fiber-to-the-home implementing method and device. The method includes: receiving, by a virtual Passive Optical Network Medium Access Control (PON MAC) of an Optical Network Unit (ONU), a first packet from an Optical Line Terminal (OLT), determining that the first packet matches the virtual PON MAC, and searching a preset corresponding relationship for a first buffer area corresponding to the virtual PON MAC receiving the first packet; buffering, by the ONU, the received first packet in the searched first buffer area; and sending, by the ONU, the first packet in the first buffer area to a user via a User Network Interface (UNI) corresponding to the first buffer area.
