Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current QoS systems face challenges such as significant resource usage, inaccurate prioritization, outdated rules, and lack of context, leading to poor network management and inefficient traffic handling.
Innovation Solution
A system that generates Universally Unique Identifiers (UUIDs) from packet headers, uses a cloud database to analyze these identifiers for context-based packet management, and provides instructions to routers for optimized traffic handling, reducing computational load on network devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If cloud-driven context-based packet classification is implemented, then packet prioritization accuracy is improved, but network device complexity increases
Solution Approach 1:
The patent introduces a cloud-based classification system as an intermediary between network devices and packet traffic management. The cloud system receives packet headers, performs context-based classification using multiple criteria (protocol type, source/destination addresses, ports, payload content), and returns classification results to network devices. This mediator handles the complex classification logic remotely, improving accuracy while keeping local devices simpler.
Solution Approach 2:
The patent moves the classification process from a single-dimension local device-based approach to a multi-dimensional cloud-based system that considers protocol type, source/destination IP addresses, port numbers, and payload content simultaneously. This dimensional expansion enables more accurate packet classification by evaluating multiple parameters in combination.
2Measurement precision
If comprehensive packet analysis is performed locally, then classification accuracy is improved, but resource usage on network devices increases
Solution Approach 1:
The patent extracts the resource-intensive packet classification function from local network devices and relocates it to a cloud-based system. Only essential packet header information is extracted and transmitted to the cloud, while the computationally heavy analysis of protocol type, addressing, ports, and payload content is performed remotely, reducing local device resource consumption while maintaining high classification accuracy.
Solution Approach 2:
The patent creates a virtual copy of the classification functionality in the cloud environment. Instead of requiring each network device to perform comprehensive analysis, a centralized cloud system performs the analysis once and provides classification results to multiple devices, efficiently distributing the computational burden and reducing redundant resource usage across the network.
3Ease of operation
If traditional QoS tagging systems are used, then traffic management is simplified, but prioritization accuracy deteriorates due to lack of context
Solution Approach 1:
The patent implements a feedback mechanism where the cloud-based classification system continuously analyzes packet characteristics and provides refined classification results back to network devices. This feedback loop enables the system to learn from traffic patterns and improve prioritization accuracy over time, while network administrators can still manage traffic using simplified QoS tagging interfaces.
Solution Approach 2:
The patent creates a universal cloud-based classification system that serves multiple network devices and traffic types simultaneously. The system handles various protocol types, addressing schemes, and traffic patterns through a single multi-functional platform, maintaining ease of operation while significantly improving prioritization accuracy through comprehensive context analysis.
Data Source
AI summary
Systems, methods, and computer-readable storage media for packet classification, and more specifically to cloud-driven traffic classification. A system can receive, at a packet identifier, a packet comprising a packet header and packet data, and generate a Universally Unique Identifier (UUID) based on the packet header. The system can then transmit the UUID from the packet identifier to a UUID cloud database and receive, at the packet identifier from the UUID cloud database, packet management instructions. The system can then provide the packet and the packet management instructions to a router.
