Function Management for Virtual CPE Bandwidth Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In virtual CPE configurations, mass transmission or simultaneous calls from user terminals can cause network bandwidth pressure between customer premises equipment (CPE) and the virtual CPE server, leading to potential disruptions in Internet communication.
Innovation Solution
A function management device and method that collect resource and network bandwidth information to activate virtual machines on CPE equipment, shifting functions with high bandwidth occupancy ratios from the virtual CPE server to the CPE, thereby reducing network load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If functions are provided by the virtual CPE server, then service flexibility and cost reduction are improved, but network bandwidth pressure increases during mass transmission or simultaneous calls
Solution Approach 1:
The patent implements dynamic function deployment by monitoring network bandwidth usage in real-time and automatically migrating functions between CPE and virtual CPE server based on current load conditions. This dynamic adjustment resolves the contradiction by allowing the system to flexibly switch between centralized and distributed function execution, maintaining service flexibility while preventing network bandwidth overload during peak usage periods
Solution Approach 2:
The patent segments functions into two categories: those executed locally on CPE and those executed remotely on the virtual CPE server. By segmenting function execution locations and using a function management device to coordinate between them, the system maintains adaptability while distributing network load, thus resolving the bandwidth pressure issue during mass transmission events
2Ease of operation
If all communication is transmitted to the center base through the virtual CPE server, then centralized function management is improved, but network stability deteriorates during peak usage
Solution Approach 1:
The function management device acts as an intermediary between CPE and the virtual CPE server, intelligently routing communication requests based on current network conditions. This intermediary maintains centralized management capabilities while preventing network instability by redirecting traffic patterns during peak usage, thus resolving the contradiction between centralized control and network stability
Solution Approach 2:
The system performs preliminary monitoring of network bandwidth usage and proactively migrates functions from the virtual CPE server to CPE before network overload occurs. This preliminary action prevents network instability while maintaining centralized management through the function management device, resolving the contradiction by anticipating and preventing problematic conditions
