Service Management Server for Dynamic QoS Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network implementations are limited in providing end-to-end Quality of Service (QoS) configurations for multiple services on a single client device, as existing methods are static and do not allow for dynamic service-specific QoS settings, leading to uniform QoS treatment for all traffic from a client interface, which is inadequate for devices requiring different service levels.
Innovation Solution
A method and arrangement that enables service-specific QoS configuration through a service management server, where client devices send requests for QoS configurations, and the server provides acknowledgement messages with service-specific QoS information, allowing intermediate nodes to enforce these settings dynamically, ensuring end-to-end QoS across multiple services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If static QoS configuration is used in current network implementations, then device complexity is reduced and ease of operation is improved, but adaptability deteriorates as all traffic from a client interface receives uniform QoS treatment regardless of service requirements
Solution Approach 1:
The patent introduces a service management server as an intermediary between client devices and the network infrastructure. This server dynamically generates and distributes service-specific QoS configuration information to intermediate nodes and client devices, enabling differentiated QoS treatment without requiring complex manual configuration at each device. The intermediary handles the complexity centrally while maintaining simplicity at the edges.
Solution Approach 2:
The patent transitions from static QoS configuration to dynamic QoS configuration. The service management server generates QoS configuration information dynamically based on service requirements and distributes it to relevant nodes. This allows the system to adapt to different services and their specific QoS needs while maintaining automated configuration management.
2Adaptability or versatility
If dynamic service-specific QoS settings are implemented, then adaptability is improved, but device complexity and automation requirements increase
Solution Approach 1:
The patent implements a self-service mechanism where the service management server automatically generates, distributes, and manages QoS configuration information without requiring manual intervention. The server responds to requests from intermediate nodes and client devices by providing appropriate QoS configurations dynamically. This automation handles the complexity internally while presenting a simple interface to users.
Solution Approach 2:
The patent establishes a feedback mechanism where intermediate nodes and client devices can request QoS configuration information from the service management server. The server processes these requests and provides appropriate configurations, creating a responsive system that adapts to specific service needs while maintaining centralized control and automation.
3Reliability
If uniform QoS treatment is applied to all traffic from a client interface, then device complexity is reduced, but service quality deteriorates as multiple services with different QoS requirements cannot be supported
Solution Approach 1:
The patent segments QoS configuration management by introducing a service management server that handles configuration generation and distribution separately from the actual QoS enforcement at intermediate nodes and client devices. This segmentation allows complex QoS requirements to be managed centrally while maintaining simple, standardized interfaces at the network edges, ensuring reliable QoS fulfillment without proportionally increasing device complexity.
