LAN-Aware QoS Orchestration for Heterogeneous Network Interoperability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Legacy network technologies provide coarse-grained quality of service (QoS) assurances, which are often vendor-specific and fail to maintain QoS when network links pass through multiple regimes, leading to inconsistencies and potential breakdowns in service quality, especially when integrating with modern networks like 5G local area networks (5GLAN).
Innovation Solution
A method and system for determining and configuring quality of service (QoS) parameters across heterogeneous networks by identifying paths through legacy local area networks (LAN) and reconfiguring devices to ensure consistent QoS, using DSCP values and rewrite rules to maintain QoS assurances for network flows from 5G radio access networks (RAN) to destination devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If legacy network technologies are used for QoS assurance, then vendor-specific QoS mechanisms can be implemented, but QoS assurances fail when network links pass through multiple different regimes
Solution Approach 1:
The patent introduces a QoS translation mechanism that acts as an intermediary between modern network slice QoS parameters and legacy network QoS parameters. This translation layer maps fine-grained modern QoS requirements into coarse-grained legacy QoS classifications, enabling seamless interoperability across heterogeneous network regimes while maintaining end-to-end QoS assurances.
Solution Approach 2:
The patent transforms QoS parameters from one domain to another by converting fine-grained modern network QoS parameters into coarse-grained legacy network QoS parameters. This parameter transformation allows the same QoS intent to be preserved across different network technologies with different QoS granularities and vendor-specific implementations.
2Measurement precision
If modern network slicing is used for fine-grained QoS, then specific QoS can be provided for different links, but legacy networks cannot maintain these fine-grained QoS levels
Solution Approach 1:
The QoS translation mechanism serves as an intermediary that receives fine-grained QoS parameters from modern network slices and converts them into appropriate coarse-grained parameters for legacy networks. This mediation preserves the precision of modern QoS specifications while adapting them to the capabilities of legacy infrastructure.
Solution Approach 2:
The patent creates a universal QoS translation framework that can handle multiple modern network QoS schemes and map them to various legacy QoS mechanisms. This multi-functional approach enables a single translation layer to support diverse QoS requirements across different network technologies and vendor implementations.
3Ease of manufacture
If vendor-specific QoS mechanisms are implemented, then QoS can be configured for specific networks, but inconsistencies arise when passing through multiple regimes
Solution Approach 1:
The patent applies parameter transformation to convert vendor-specific QoS parameters into a standardized intermediate representation, then maps this to the appropriate legacy QoS parameters at each network regime. This systematic parameter conversion maintains consistency across multiple vendor-specific implementations while preserving the intended QoS characteristics.
Solution Approach 2:
The translation mechanism acts as a mediator that normalizes vendor-specific QoS parameters into a common format, ensuring consistent interpretation and application across different network regimes. This intermediary layer prevents QoS parameter inconsistencies by providing a standardized translation path through heterogeneous network infrastructure.

AI summary
Methods and systems for transmission over a heterogeneous network include determining a path through a first network, including collecting quality of service (QoS) parameters for network devices in the path. The QoS parameters of the network devices are configured to provide a predetermined QoS assurance across the path. A network flow is transmitted from a network slice of a second network through the first network, along the path.
