TSN Translator Port Pairing for Accurate Bridge Delay Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing time-sensitive networks face challenges in managing and controlling bridge-related information due to shared network resources, data transmission delays, and the inability to distinguish between device-side and network-side Time-Sensitive Network Translators (TSN Translators), leading to inaccurate delay calculations and port pair management.
Innovation Solution
The method and device provide mechanisms for obtaining and sending port-related information, including determining the type and delay information of Time-Sensitive Network Translators (TSN Translators), enabling the formation of port pairs and accurate delay calculations, thereby supporting the management and control of bridge-related information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network transmission resources are shared, then resource utilization is improved, but data transmission delay and jitter increase
Solution Approach 1:
The patent segments network resources by introducing time-sensitive network resources separate from general network resources. Time-sensitive data streams are transmitted through dedicated resources that are segmented from shared resources, ensuring deterministic delay bounds while maintaining high utilization of both resource types.
Solution Approach 2:
The patent introduces bridge-related information as an intermediary mechanism that manages the interaction between time-sensitive and general network resources. This intermediary enables coordinated resource allocation and delay calculation across different network domains.
2Device complexity
If bridge-related information is not accurately managed, then device complexity is reduced, but delay calculation accuracy deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-establishing bridge-related information including port pairs, delay values, and translator types before time-sensitive data transmission. This pre-configuration enables accurate delay calculations without requiring complex real-time computations, thus maintaining low device complexity while ensuring high measurement precision.
3Device complexity
If device-side and network-side TSN Translators are not distinguished, then device complexity is reduced, but port pair management accuracy deteriorates
Solution Approach 1:
The patent applies local quality by introducing distinct identification characteristics for device-side and network-side TSN Translators. Each translator type has specific attributes (such as location-relative identifiers) that enable precise differentiation. This localized quality enhancement allows accurate port pair management without significantly increasing overall device complexity.
