Hierarchical Proxy Deployment for 5G Latency and Bandwidth Constraints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing proxy deployment solutions in 5G/B5G networks are inflexible regarding the number and location of proxies, limiting the enhancement of network transmission capacity and failing to meet the stringent performance requirements of applications like higher bandwidth, lower latency, and data transmission rate.
Innovation Solution
A hierarchical proxy deployment method is introduced, involving a secondary base station node, master base station node, cloud proxy node, and long connection proxy node, with flexible deployment of proxies based on collected bandwidths and latencies to optimize proxy locations and numbers, using a calculation formula for time to first byte (TTFB) to select the optimal deployment solution.

Engineering Contradiction Analysis
1Ease of manufacture
If a predetermined number of proxies is deployed on specific network nodes, then the deployment is simple, but the flexibility of proxy number and location is poor, limiting network transmission capacity enhancement
Solution Approach 1:
The patent segments the proxy deployment into multiple hierarchical levels (core network proxies, edge network proxies, and local proxies) rather than deploying all proxies at a single level. This segmentation enables flexible deployment at different network locations while maintaining management simplicity through hierarchical structure.
Solution Approach 2:
The patent introduces a hierarchical dimension to proxy deployment, organizing proxies into multiple levels (core, edge, local) rather than a single flat layer. This dimensional change provides flexibility in both the number and location of proxies while maintaining deployment simplicity through structured organization.
2Productivity
If more proxies are deployed to enhance network transmission capacity, then the transmission performance improves, but the network overhead and resource consumption increase
Solution Approach 1:
The patent deploys proxies with different functions at different network locations: core network proxies handle protocol conversion and traffic management, edge network proxies handle local traffic optimization, and local proxies handle specific application optimization. This local differentiation optimizes transmission capacity while minimizing overall network overhead by placing only necessary proxy functions at each location.
Solution Approach 2:
The patent implements a selective proxy deployment strategy where only necessary proxy functions are deployed at each network level based on local requirements. Rather than deploying all proxy functions everywhere, the system applies partial proxy deployment at each level, reducing overall network overhead while maintaining sufficient transmission capacity enhancement.
3Speed
If proxies are deployed to meet transmission performance requirements, then the data transmission rate improves, but the complexity of determining optimal proxy number and location increases
Solution Approach 1:
The patent segments proxy deployment into hierarchical levels with clearly defined roles: core network proxies for protocol conversion, edge network proxies for local optimization, and local proxies for application-specific optimization. This segmentation simplifies the complexity of determining optimal deployment by providing a structured framework where each level has specific deployment criteria.
Solution Approach 2:
The patent establishes a preliminary hierarchical proxy deployment framework before actual deployment, defining the structure and roles of proxies at each level in advance. This preliminary action provides clear guidance for determining optimal proxy number and location, reducing deployment complexity by pre-establishing the deployment methodology and decision criteria.
Data Source
AI summary
A hierarchical proxy deployment method includes: performing information collection and information interaction in a hierarchical proxy deployment architecture to obtain bandwidths and latencies of all inter-node communication links; and selecting an optimal proxy deployment solution from all feasible proxy deployment solutions based on the bandwidths and latencies of all the inter-node communication links. According to the method, a hierarchical proxy deployment architecture is used. An optimal proxy deployment solution is formed by selecting the optimal location and the optimal number of proxies for deployment to meet the transmission performance requirement of network applications in 5G/B5G networks. Therefore, transmission performance requirements are satisfied by a proxy deployment with a minimized number of proxies, thereby reducing network overheads and resource waste.
