Decoupled Message Processor for Passive Optical Network Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of processing OMCI/OAM messages in passive optical networks (PONs) leads to high maintenance costs due to the intricate processing functions and interactions within the optical line terminal (OLT), which complicates the management and control of optical network units (ONUs).
Innovation Solution
A message transmission method where a message processor, decoupled from the OLT, obtains and encapsulates message content with ONU addresses into Ethernet or IP packets, and sends them to a relay device using OpenFlow messages or tunnels like VXLAN or MPLS, allowing the relay device to forward messages to the ONU, thereby simplifying the processing and maintenance of the OLT and ONU interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the message processor is integrated within the OLT to process OMCI/OAM messages, then the message processing function is achieved, but the device complexity and maintenance costs increase
Solution Approach 1:
The patent segments the OLT into two independent components: a relay device that handles message forwarding and a separate message processor that handles message processing. This segmentation allows the message processor to be maintained independently, reducing the complexity and maintenance costs of the OLT while preserving complete message processing functionality.
Solution Approach 2:
The message processor is extracted from the OLT and placed outside it. The OLT retains only the relay device function for forwarding messages, while the message processor is deployed as an independent entity that can be maintained separately, thus reducing the complexity of the OLT system.
2Reliability
If the message processor is integrated within the OLT, then message processing is performed, but maintenance costs increase due to complex processing functions
Solution Approach 1:
By segmenting the message processing function from the OLT and placing it in a separate message processor, the system allows independent maintenance of each component. This reduces maintenance costs as the complex processing functions can be maintained separately from the OLT hardware.
Solution Approach 2:
The relay device acts as an intermediary between the OLT and the separate message processor, enabling communication and message forwarding while allowing the message processor to be maintained independently, thus reducing overall maintenance costs.
3Ease of repair
If the message processor is decoupled from the OLT and placed outside, then maintenance costs are reduced, but the message transmission path becomes more complex
Solution Approach 1:
The relay device serves as an intermediary that simplifies the message transmission path between the separate message processor and the OLT. It handles message forwarding using standard protocols, making the transmission path manageable despite the physical separation of components.

AI summary
Embodiments of the present invention provide a message transmission method, a relay device, and a message processor, so as to reduce maintenance costs. The method includes: receiving, by a relay device, a downlink message sent by a message processor, where the downlink message includes message content and an address of an ONU; obtaining, by the relay device according to the downlink message, an identifier, of the ONU, corresponding to the address of the ONU; and sending, by the relay device, the message content to the ONU according to the identifier of the ONU.
