Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple management platforms are used to capture packets on multiple ASON nodes, then the coverage of packet capture is improved, but the network structure becomes more complicated and network resources are wasted
Solution Approach 1:
The patent merges multiple packet capture functions into a single management platform by establishing a centralized signaling tracking system that collects signaling messages from multiple ASON nodes through a unified interface, eliminating the need for multiple independent management platforms and reducing network structural complexity
Solution Approach 2:
The management platform is designed with universal functionality to handle packet capture and signaling tracking across multiple ASON nodes simultaneously, allowing a single platform to perform what previously required multiple specialized platforms
2Measurement precision
If multiple management backgrounds are used to capture packets on multiple nodes, then the capture scope is expanded, but uniform resolution of network element data according to data sequence cannot be guaranteed
Solution Approach 1:
The patent combines multiple packet capture operations into a single centralized management platform that maintains unified control over all captured data, ensuring consistent resolution of network element data across all nodes through a single data sequence management mechanism
3Adaptability or versatility
If existing packet capturing tools are used in ASON, then the capture function is provided, but the filtering conditions are inflexible and inapplicable to ASON
Solution Approach 1:
The patent changes the filtering parameters from traditional IP-based filters to ASON-specific signaling message filters that can identify and track signaling messages based on ASON protocol characteristics, node identifiers, and service types, making the filtering conditions both flexible and applicable to ASON networks
4Quantity of substance
If a packet capturing tool captures all signaling of an ASON node, then complete signaling data is obtained, but it is impossible to find the message corresponding to a desired service from the captured packet
Solution Approach 1:
The patent extracts only the relevant signaling messages corresponding to desired services from the complete signaling data by implementing service-specific filtering mechanisms that identify and extract targeted messages based on service identifiers and signaling flow patterns, eliminating the need to manually search through all captured packets

AI summary
The present invention discloses a method and system for tracking signaling in an automatically switched optical network (ASON), wherein the method comprises a step of setting a signaling tracking filtering condition for a corresponding signaling tracking task, and the following steps that: an ASON node collects and reports a received or sent signaling message when there exists a task tracking request; and when the reported signaling message is determined meeting the signaling tracking filtering condition of the current signaling tracking task, the reported signaling message is resolved to obtain the signaling message of the signaling tracking task. The invention realizes a signaling tracking scheme in an ASON and can establish multiple signaling tracking tasks at the same time, as each signaling tracking task can set its own signaling tracking filtering condition; a flexible signaling tracking is achieved. The invention provides a means for resolving a signaling process and locating a fault in a field debugging and a subsequent operation and maintenance, thus improving the efficiency of fault location.
