Multi-Chassis Port Domain Generation for Network Error Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As communication networks become increasingly complex, coordinating multiple ports in a multi-chassis system to accurately represent the time sequence of data transmitted across multiple channels or data links becomes a challenge, particularly in diagnosing network errors and optimizing network performance.
Innovation Solution
The method involves creating port domains by interconnecting multiple chassis through an interconnection means, such as a sync-cable, and using microprocessors to select and generate port domains based on the relative locations of ports, allowing for the generation of both global and local port domains, enabling coordinated data capture and analysis across the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple ports in a multi-chassis system are coordinated to accurately represent the time sequence of data transmitted across multiple channels, then network error diagnosis and performance optimization are improved, but the system complexity increases
Solution Approach 1:
The patent segments the multi-chassis system into independent chassis units, each capable of generating its own port domains. This segmentation allows accurate time sequence representation at each chassis level while reducing the coordination complexity across the entire system by processing data locally rather than requiring centralized coordination.
Solution Approach 2:
The patent introduces a new organizational dimension by creating port domains that group ports based on their physical location and operational context rather than simply listing all ports sequentially. This dimensional reorganization enables accurate time sequence representation while managing system complexity through structured port domain generation.
2Quantity of substance
If the number of port domains is increased to accommodate more ports, then the system can analyze more network traffic, but the processing overhead increases
Solution Approach 1:
The patent applies local quality by generating port domains based on the specific characteristics and locations of individual ports rather than uniformly processing all ports. This allows the system to efficiently analyze only the relevant ports for each network condition, reducing processing overhead while maintaining comprehensive analysis capability.
Solution Approach 2:
The patent implements dynamic port domain generation where the system can adaptively create and modify port domains based on real-time network conditions and traffic patterns. This dynamic approach enables the system to process only the necessary ports at any given time, reducing overall processing overhead while maintaining the ability to analyze extensive network traffic when needed.

AI summary
Creation of port domains in a multi-chassis system. The multi-chassis system includes two or more chassis that each includes one or more blades. In one embodiment, a sync group of at least two chassis is created, typically by connecting the two or more chassis with an interconnection means such as a sync-cable. Then, two or more ports of the sync group are selected for inclusion in a port domain. The locations of the ports relative to each other is then determined. Finally, a port domain is generated based on the relative locations of the ports and port domain generation rules. If the ports are on separate chassis, then a global domain is generated if a predetermined number of global domains do not already exist and if the ports are on the same chassis, a local domain is generated regardless of the number of global domains.
