Solution Overview
Problem
Data center networks face challenges in optimizing network performance and resource utilization due to the lack of traffic prioritization, leading to delays and bottlenecks, especially when managing diverse applications and services.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If network traffic is treated equally without prioritization, then network simplicity is maintained, but network performance and resource utilization deteriorate due to delays and bottlenecks
Solution Approach 1:
The patent segments network traffic into different priority classes (e.g., high priority, medium priority, low priority) based on application type, user role, or task criticality. This segmentation allows differentiated QoS treatment for different traffic types, resolving the contradiction by introducing structured complexity that improves performance while maintaining manageable organization.
Solution Approach 2:
The patent implements dynamic traffic prioritization where QoS parameters such as bandwidth allocation, packet scheduling, and latency tolerance are adjusted in real-time based on current network conditions, user priorities, and task requirements. This dynamic adaptation enables the system to optimize performance automatically without requiring complex static configurations.
2Productivity
If bandwidth is allocated equally to all traffic, then network configuration simplicity is maintained, but throughput and resource utilization deteriorate
Solution Approach 1:
The patent applies local quality by assigning different bandwidth allocations and QoS parameters to different traffic classes based on their specific requirements. High-priority traffic receives guaranteed bandwidth and low latency treatment, while low-priority traffic receives best-effort service. This localized differentiation optimizes throughput for critical applications without requiring complex global reconfiguration.
Solution Approach 2:
The patent changes QoS parameters such as bandwidth percentage, packet transmission rate, and latency tolerance dynamically based on traffic priority levels. By adjusting these parameters according to traffic class rather than using fixed equal allocation, the system achieves optimized throughput while maintaining manageable parameter configuration through standardized priority classes.
3Loss of time
If all network traffic is handled with same latency tolerance, then system simplicity is maintained, but time-sensitive operations suffer from delays
Solution Approach 1:
The patent segments traffic into latency-sensitive and latency-tolerant classes, applying different handling mechanisms to each. Time-sensitive traffic (e.g., real-time communication, critical transactions) receives prioritized processing with guaranteed low latency, while non-time-sensitive traffic (e.g., batch processing, non-critical data transfer) tolerates higher delays. This segmentation reduces overall latency for critical operations without requiring complex universal solutions.
Solution Approach 2:
The patent implements dynamic latency management where packet scheduling and routing decisions adapt in real-time based on traffic priority and network conditions. High-priority packets are scheduled for immediate transmission during available bandwidth windows, while lower-priority packets wait in queues. This dynamic approach minimizes latency for critical traffic without requiring complex static latency guarantees for all traffic.

AI summary
A system and a method for prioritizing network traffic using application awareness and network awareness in a network environment is disclosed. An exemplary method can include receiving a network traffic priority for network traffic associated with a job performed by a distributed application; and based on the network traffic priority, assigning the network traffic to a network classification model, such as an access control list, associated with a network element for directing the network traffic in a network. The network classification model is associated with a network traffic priority class having defined quality of service (QoS) features, such that the network traffic traverses the network according to the defined QoS features.
