Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of a fault information transmission scheme for joint networking that combines standard Ethernet and flexible Ethernet protocols, which is essential for efficient communication in modern networks where standard Ethernet protocols deviate from actual application requirements, leading to resource waste and inefficient bandwidth utilization.
Innovation Solution
A communication method and device that include a fault information processing module to generate and transmit second-type fault information based on first-type fault information, using a flexible Ethernet protocol to indicate link faults in standard Ethernet protocols, thereby enabling fault reporting and determining the faulty protocol in joint networking environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard Ethernet protocol is used for fault information transmission in joint networking, then compatibility with existing protocols is maintained, but fault information cannot be accurately transmitted across protocol boundaries leading to mistaken protection switching triggers
Solution Approach 1:
The patent introduces a dedicated fault information transmission mechanism that acts as an intermediary between standard Ethernet and flexible Ethernet protocols. This intermediary layer translates and forwards fault information accurately across protocol boundaries, preventing mistaken protection switching triggers while maintaining compatibility with existing protocols.
2Productivity
If flexible Ethernet protocol is used to enable fine-grained bandwidth allocation, then bandwidth utilization efficiency is improved, but device complexity increases due to protocol integration requirements
Solution Approach 1:
The patent segments the protocol handling into distinct modules: standard Ethernet protocol processing, flexible Ethernet protocol processing, and fault information transmission. This segmentation allows each module to be independently optimized and managed, reducing overall device complexity while enabling fine-grained bandwidth allocation through flexible Ethernet.
3Reliability
If fault information transmission is implemented in joint networking, then fault detection capability is improved, but bandwidth occupation increases due to additional information transmission
Solution Approach 1:
The patent extracts fault information transmission as a separate, dedicated function from the main data transmission channel. By using specific overhead fields and control blocks exclusively for fault information, the solution improves fault detection capability without significantly occupying bandwidth used for data transmission.

AI summary
A communication method, a communications device, and a storage medium are provided, to transmit fault information in joint networking in which a standard Ethernet protocol and a flexible Ethernet protocol are used. In embodiments of this application, first fault information is obtained by using a first port, and second fault information is sent based on the first fault information by using a second port. The first port is a first-type port, the first-type port transmits information according to a standard Ethernet protocol, the first fault information is first-type fault information, the second port is a second-type port, the second-type port transmits information according to a flexible Ethernet protocol, the first-type fault information includes at least one of local fault information and remote fault information, the second fault information is second-type fault information, and the second-type fault information is used to indicate that a link corresponding to the standard Ethernet protocol is faulty. In this way, a fault can be reported in joint networking in which the standard Ethernet protocol and the flexible Ethernet protocol are used.
