QoS Model Consolidation for Dynamic Network Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Quality of Service (QoS) models in packet switched networks, such as IntServ and Diffserv, face challenges in scalability and management, particularly in dynamically changing network conditions where QoS models proliferate undesirably, leading to inefficient resource allocation and potential service level agreement (SLA) breaches.
Innovation Solution
The method involves monitoring network traffic to select and manage QoS models based on stability, performance, and desirability indicators, allowing for the reduction of QoS models by withdrawing those that do not meet promised levels or are redundant, and promoting desirable traffic characteristics, thereby optimizing resource allocation and ensuring compliance with SLAs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If QoS models are dynamically discovered based on monitoring route performance, then the system can adapt to changing network conditions, but QoS models may proliferate undesirably leading to management difficulties
Solution Approach 1:
The patent merges multiple discovered QoS models into a single consolidated model by identifying common performance characteristics among multiple routes. Instead of maintaining separate QoS models for each route or cluster, the system aggregates routes with similar performance profiles and creates unified QoS models, thereby reducing model proliferation while preserving adaptability to different network conditions.
Solution Approach 2:
The patent creates universal QoS models that can represent multiple routes with similar performance characteristics. A single QoS model serves multiple routes by capturing their common performance profile, allowing the system to maintain adaptability across diverse network conditions while using a reduced set of reusable models.
2Adaptability or versatility
If multiple QoS models are maintained to cover various network conditions, then service coverage is improved, but resource allocation becomes inefficient
Solution Approach 1:
The system consolidates resource allocation by merging multiple QoS models into unified models. This reduces the overhead of managing and allocating resources across numerous separate models, improving resource allocation efficiency while maintaining comprehensive service coverage through the aggregated model representations.
3Reliability
If QoS models are frequently updated to reflect current network performance, then service quality is improved, but management overhead increases
Solution Approach 1:
The system reduces management overhead by merging updates across multiple QoS models. When performance characteristics change, the system updates the consolidated models rather than individually managing numerous separate models, thereby maintaining service quality while reducing the complexity of model management.
4Reliability
If IntServ resource reservation is implemented to guarantee QoS, then transmission reliability is improved, but system scalability deteriorates
Solution Approach 1:
The patent applies universal QoS models that can be reused across multiple routes and traffic flows, reducing the need for individual resource reservations for each flow. This maintains transmission reliability through guaranteed QoS while improving scalability by eliminating the need for complex per-flow reservation management.

AI summary
The present invention provides a method of providing QoS models for a communications network in which: data is obtained data describing a plurality of QoS models, with each QoS model containing at least one QoS component specifying a characteristic of network traffic to be provided by the QoS model; monitoring network traffic to obtain a plurality of indicators, each indicating a characteristic of the network traffic associated with one of the QoS models; selecting, based on the indicators, a subset of the plurality of QoS models; and providing data identifying the subset of QoS models to a client device to enable the client device to send data over the network according to a selected one of the subset of QoS models.
