Application-Aligned NaaS Control for Dynamic Session Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network service paradigms, such as network slicing, fail to meet the dynamic and intricate needs of applications like holographic collaboration, leading to inefficiencies and increased costs due to rigid service delivery models and lack of real-time control over network resources.
Innovation Solution
The introduction of Application-Aligned Network-as-a-Service (NaaS) APIs (AA-NAPIs) allows applications to control network resources through intelligent application controllers (IACs) that map application object references to network objects, enabling dynamic and cost-effective management of network functions and connectivity based on application-specific requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network slicing is used for application-network interaction, then network service delivery is standardized, but it cannot meet the dynamic and intricate needs of applications like holographic collaboration
Solution Approach 1:
The patent segments the network service model into distinct layers: application layer, NaaS layer, and network layer. The NaaS layer acts as an intermediary that segments complex network operations into manageable service units that applications can consume without understanding underlying complexity.
Solution Approach 2:
The NaaS layer serves as an intermediary between applications and the network infrastructure. It provides translation and mediation capabilities, allowing applications to interact with the network through simplified interfaces while the NaaS layer handles the complexity of network resource management and orchestration.
2Productivity
If applications are given direct control over network resources, then optimal network utilization is achieved, but applications are exposed to network complexities
Solution Approach 1:
The NaaS layer acts as an intermediary that shields applications from network complexity while enabling efficient resource utilization. It provides abstraction mechanisms that allow applications to request network resources based on their needs without exposing the intricate details of network management.
Solution Approach 2:
The system enables applications to self-manage their network resources through automated orchestration. The NaaS layer provides self-service capabilities where applications can dynamically allocate and manage network resources based on their requirements without manual intervention or deep knowledge of network operations.
3Reliability
If premium network services are always activated, then Quality-of-Experience is maximized, but operational costs increase
Solution Approach 1:
The patent implements dynamic service level adjustment where the network service quality is adapted in real-time based on application needs and conditions. The system can transition between different service levels (premium, standard, basic) dynamically, activating premium services only when necessary and switching to lower-cost services when full performance is not required.
Solution Approach 2:
The system changes network service parameters dynamically based on application requirements and operational conditions. It adjusts service quality parameters, resource allocation parameters, and cost parameters in response to changing demands, allowing optimal balance between Quality-of-Experience and operational cost.

AI summary
An application specific interface (AA-NAPI) associated with an application for the purpose of controlling the networking aspects of the application session is provided by communication service provider (CSP). Cost model of network service types associated with a specific application type is learned by using the AA-NAPI. For each service-point joining the session, network properties are queried by using the AA-NAPI. During continuous service quality monitoring, upon detection of quality degradation leading to the decision to upgrade session quality, network service-type associated with a specific server-point is changed by using the AA-NAPI. Network specific actions are taken to reconfigure the network so that the requested service type is received by the specific service-point. New network capability is activated to improve network service level by using the AA-NAPI. Network specific actions are taken by the network to install new network capabilities so that the specific service-point's service quality is improved as requested.
