Network Traffic Flow Management via QoS Reservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network technologies face challenges in managing traffic flow for quality of service (QoS) in multimedia and collaboration applications, particularly in ensuring reserved bandwidth and minimizing packet delays across wireless network paths.
Innovation Solution
The solution involves network devices, such as clients and access points, determining traffic specification values based on session parameters and assigning priority to each stream, which enables QoS reservations and resource allocation on the network path, ensuring appropriate bandwidth reservation for sensitive traffic instances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network devices manage traffic flow without QoS reservations, then network flexibility and ease of operation are maintained, but bandwidth reservation reliability and packet delay performance deteriorate
Solution Approach 1:
The system performs QoS reservations and traffic specification configurations in advance before actual data transmission occurs. Network devices pre-establish bandwidth reservations and priority assignments for different traffic streams, ensuring that when multimedia or collaboration applications transmit data, the QoS parameters are already in place to guarantee reliable bandwidth allocation and minimize packet delays.
Solution Approach 2:
The patent introduces an intermediary mechanism that translates application-layer QoS requirements into network-layer traffic specifications. This intermediary layer automatically maps application performance requirements to appropriate network parameters, eliminating the need for manual network configuration while ensuring reliable bandwidth reservation through automated QoS policy enforcement.
2Reliability
If network devices implement automated QoS reservations based on traffic specifications, then bandwidth reservation reliability improves, but device complexity increases
Solution Approach 1:
Network devices automatically perform QoS reservations and traffic flow management without requiring manual configuration or complex intervention. The system self-services by automatically translating application QoS requirements into network traffic specifications, dynamically allocating bandwidth, and managing priority queues based on real-time traffic conditions, thereby reducing the perceived complexity for users while maintaining high reliability.
Solution Approach 2:
The patent dynamically adjusts network parameters such as bandwidth allocation, packet priority, and queue management based on changing traffic conditions and application requirements. By automatically modifying these parameters in response to real-time network state and QoS demands, the system achieves reliable QoS reservations without requiring complex static configurations, thereby reducing device complexity while maintaining reliability.
3Loss of time
If network devices prioritize traffic streams based on traffic specifications, then packet delay performance improves, but processing complexity increases
Solution Approach 1:
The network system segments traffic into distinct streams based on application type and QoS requirements, creating separate priority queues for different traffic categories. By dividing traffic flow into manageable segments with predefined priority levels, the system can efficiently process each segment according to its specific requirements, minimizing packet delay for time-sensitive applications while avoiding the complexity of handling all traffic uniformly.
Solution Approach 2:
The patent dynamically changes traffic priority parameters based on real-time network conditions and application requirements. Network devices automatically adjust priority levels, bandwidth allocations, and queue management parameters according to the specific needs of each traffic stream, enabling optimized packet delay performance without requiring complex manual configuration of each individual flow.

AI summary
A network device determines the traffic specification values based on the session values that represent the application parameters of an application, which is provided differentiated service levels. A user of the network device may provide and/or choose the session values. The network device may generate one or more streams corresponding to a plurality of the applications. Each stream may comprise one or more traffic instances. The network device may assign a priority value to each stream and instance identifier to each traffic instances within the stream to manage the transfer of data units.
