Solution Overview

Problem

The existing virtualized broadband remote access server (VBRAS) lacks dynamic management capabilities for its protocol component, leading to inefficient resource utilization and user experience degradation due to bottlenecks and redundant resource allocation.

Innovation Solution

A control method and apparatus that dynamically manage the protocol component by obtaining performance parameters such as user count, memory, and CPU utilization rates, enabling capacity expansion or shrinkage by activating or hibernating protocol components within a shared resource pool, thereby optimizing resource usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the protocol component capacity is expanded in advance to handle potential user load, then user service quality is improved, but resource waste increases when user load is low

Engineering Contradiction:

Improveuser service qualityVSAvoidresource waste

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent implements dynamic capacity adjustment of the protocol component based on real-time monitoring of online user numbers. When the number of online users exceeds a preset threshold, the system activates additional protocol components to handle the load. When users go offline and load decreases, the system deactivates unnecessary components. This dynamic adaptation resolves the contradiction by ensuring sufficient capacity during high load while minimizing resource consumption during low load periods.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system continuously monitors the number of online users and uses this feedback to adjust protocol component capacity. The preset threshold acts as a trigger point that initiates capacity expansion or contraction. This feedback mechanism ensures that resource allocation is continuously optimized based on actual demand, preventing both over-provisioning and under-provisioning of resources.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If the protocol component capacity is shrunk to release resources, then resource utilization is improved, but user experience deteriorates due to processing bottlenecks

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements network function virtualization that separates the control plane from the data plane, allowing the same physical hardware to host multiple virtualized BRAS services. The virtualized protocol component can be dynamically instantiated, activated, or deactivated based on service requirements. This universal platform supports multiple services and providers on the same infrastructure, dramatically improving device substitutability while maintaining service reliability through virtualization isolation and management.
