Service Function Chain Request Processing via Domain Classification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional network architectures face challenges in efficiently processing high-speed data traffic due to increased latency and resource wastage in physical devices, especially with the rise of high-bandwidth services, where optical interconnecting technology is not suitable for frequent connects/disconnects and VNFs with varying data processing rates lead to resource competition and network performance degradation.
Innovation Solution
A method and system for processing service function chain requests by classifying requests into optical or electrical domains, distributing them accordingly, selecting servers with minimal resources, and dynamically adjusting VNF deployments based on real-time network and service state monitoring to optimize resource utilization and reduce latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If optical interconnecting technology is used for high-bandwidth services, then bandwidth capacity and transmission speed are improved, but processing flexibility and adaptability to frequent connects/disconnects deteriorate
Solution Approach 1:
The system segments service function chain requests into different categories (high-speed/low-burst vs. low-speed/high-burst) and routes them to appropriate processing domains (optical vs. electrical), allowing each domain to operate in its optimal performance regime
Solution Approach 2:
An intermediary classification and routing mechanism is introduced between the service function chain request and the processing domain, determining whether optical or electrical domain processing is more suitable based on request characteristics
2Productivity
If VNFs with high data processing rates are deployed, then processing capacity is improved, but resource utilization efficiency deteriorates due to resource occupation for low-rate services
Solution Approach 1:
The system applies local quality by matching VNF processing capabilities to service requirements - high-rate VNFs are allocated to high-throughput services while low-rate VNFs handle bursty traffic, ensuring optimal resource utilization without over-provisioning
Solution Approach 2:
The system dynamically adjusts VNF deployment parameters based on service characteristics, selecting appropriate data processing rates and resource allocations to match actual traffic demands rather than using fixed high-rate configurations
3Device complexity
If service function chain requests are processed without classification, then system complexity is reduced, but processing latency increases due to suboptimal resource allocation
Solution Approach 1:
The system performs preliminary classification of service function chain requests based on their characteristics (data rate, burstiness) before routing to processing domains, enabling optimal path selection and reducing processing latency through advance decision-making
