Solution Overview
Problem
Existing OAM standards often lag behind link standards, and devices struggle to support OAM functions due to different processing methods, necessitating a flexible method for processing OAM packets to adapt to varying standards without hardware changes.
Innovation Solution
A method and system where a network device receives OAM instructions from an OAM server, generates OAM packets according to provided format information, and sends them to designated targets, allowing for flexible OAM processing by adapting to different standards through reserved OAM processing capabilities, including flow table construction and recording results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If OAM function is supported by link processing hardware, then OAM processing capability is improved, but device complexity increases and adaptability to different OAM standards deteriorates
Solution Approach 1:
The patent introduces a centralized OAM server as an intermediary that generates and manages OAM instructions for multiple network devices. The server maintains a unified OAM standard and translates it into device-specific instructions, allowing hardware to maintain stable processing capabilities while adapting to different OAM standards through software-based instruction translation rather than hardware modification.
Solution Approach 2:
The OAM server is designed to support multiple OAM standards and protocols simultaneously, providing universal OAM processing capability. It can generate OAM instructions for different device types and standards (Ethernet OAM, MPLS OAM, etc.) through a single platform, eliminating the need for separate hardware implementations for each standard.
2Adaptability or versatility
If OAM standard is introduced later, then device compatibility is improved, but processing flexibility deteriorates due to different processing methods
Solution Approach 1:
The patent implements automatic flow table construction and configuration management through the OAM server. When new OAM standards or protocols are introduced, the server automatically generates corresponding flow table construction instructions and configures network devices without manual intervention. This self-service mechanism maintains processing flexibility while ensuring compatibility with new standards.
Solution Approach 2:
The OAM system employs dynamic flow tables that can be automatically constructed and updated based on received OAM packets and standards. The flow table construction instructions enable the system to adapt its processing methods dynamically rather than relying on static, pre-configured processing logic, thereby maintaining flexibility when new OAM standards are introduced.
3Productivity
If different devices use different processing methods, then device-specific optimization is improved, but system consistency deteriorates
Solution Approach 1:
The patent applies local quality by allowing each network device to have optimized processing capabilities tailored to its specific hardware characteristics and capabilities. The OAM server generates device-specific OAM instructions that leverage each device's unique strengths while maintaining overall system consistency through centralized coordination and unified OAM standard enforcement at the server level.
