Network Edge Routing Device Flow Mapping to Classes of Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network edge routing devices lack the capability to inform computing devices within their network how to optimally map data flows to classes of service, leading to non-optimal data flow disruption and throughput when class-based network frame flow control is initiated, especially in scenarios with multiple network ports or destinations.
Innovation Solution
The network edge routing device determines and communicates a mapping between network frame flows and classes of service to the computing device, allowing it to intelligently tag network frames with appropriate classes of service, minimizing disruption and maximizing throughput during class-based priority flow control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If network edge routing devices do not provide mapping information to computing devices, then the system is simpler to operate, but data flow disruption increases and throughput decreases during class-based priority flow control
Solution Approach 1:
The computing device autonomously determines and applies the mapping between network frame flows and classes of service based on information provided by the network edge routing device, enabling self-configuration without manual intervention and optimizing throughput during flow control events
Solution Approach 2:
The network edge routing device acts as an intermediary that communicates mapping information to computing devices, enabling them to make intelligent tagging decisions without direct human configuration while maintaining system-wide optimization
2Device complexity
If network edge routing devices do not provide mapping information to computing devices, then device complexity is reduced, but data flow disruption increases during class-based priority flow control
Solution Approach 1:
The mapping determination function is extracted from the network edge routing device and implemented at the computing device, reducing complexity at the routing device while maintaining reliability through distributed intelligence
Solution Approach 2:
The network edge routing device provides mapping information as an intermediary solution, enabling computing devices to independently make tagging decisions that maintain transmission reliability without centralizing complexity
3Ease of manufacture
If computing devices use non-optimal mapping of data flows to classes of service, then ease of configuration is improved, but data flow disruption increases during class-based priority flow control
Solution Approach 1:
The mapping between network frame flows and classes of service is determined in advance by the network edge routing device and communicated to computing devices, enabling them to pre-configure optimal tagging strategies before flow control events occur
Solution Approach 2:
The network edge routing device serves as an intermediary that provides pre-calculated mapping information, enabling computing devices to configure themselves optimally without manual intervention or complex algorithms

AI summary
A network edge routing device determines a mapping between network frame flows and classes of service that minimizes network frame flow disruption during class-based network frame flow control initiated outside a network of the network edge routing device. The network edge routing device transmits the mapping to a network interior device within the network that generates the network frame flows. The network edge routing device receives the network frame flows from the network interior device from inside the network, and routes the network frame flows to outside the network.
