Dual-Protocol Ethernet Port Adaptation via Peer Capability Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Ethernet standards lack flexibility to accommodate bandwidth requirements that fall between standard rates, leading to inefficiencies such as resource wastage or inability to support specific service speeds like 200 Gb/s, necessitating a communication solution for ports supporting both flexible and standard Ethernet protocols.
Innovation Solution
A communication method and device that determine and adapt to the protocol type supported by a peer port, enabling communication between ports supporting flexible Ethernet and standard Ethernet protocols by using physical coding sublayer (PCS) code blocks and control packets to ensure protocol compatibility and efficient information exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a port supports both flexible Ethernet protocol and standard Ethernet protocol to accommodate different bandwidth requirements, then adaptability is improved, but device complexity increases
Solution Approach 1:
The port dynamically switches between flexible Ethernet protocol and standard Ethernet protocol based on the detected protocol type of the peer port. The system transitions from a static protocol configuration to a dynamic adaptation mechanism, where the operating protocol is determined in real-time based on peer capabilities and requirements, thereby managing complexity through operational flexibility rather than structural complexity
Solution Approach 2:
The system changes the protocol parameter state based on peer port detection results. By monitoring and detecting the protocol type of the peer port, the system adjusts its own protocol configuration parameter to match the peer's capabilities, enabling seamless transition between different protocol modes without manual intervention and reducing the operational burden of managing multiple protocols
2Adaptability or versatility
If protocol detection and adaptation mechanisms are implemented to enable communication between different protocol types, then adaptability is improved, but time overhead increases
Solution Approach 1:
The system performs preliminary protocol type detection during the connection establishment phase before actual data transmission begins. By detecting and determining the peer port's protocol type in advance through capability exchange, the system pre-configures the appropriate protocol parameters and switching mechanisms, eliminating the need for time-consuming protocol negotiation during ongoing data transmission and minimizing operational time overhead

AI summary
Communication methods, apparatuses, systems, and storage media are provided, to implement communication between a port and another port supporting both a flexible Ethernet protocol and a standard Ethernet protocol. In an example, a port of a first device supports a flexible Ethernet protocol and a standard Ethernet protocol, and a protocol type supported by a port of a second device includes the flexible Ethernet protocol and/or the standard Ethernet protocol. The first device obtains the protocol type supported by the port of the second device, determines a target protocol type based on the protocol type supported by the port of the second device and a protocol type supported by the port of the first device, and communicates with the second device based on the target protocol type. The target protocol type includes the flexible Ethernet protocol or the standard Ethernet protocol.
