Proxy Server for Internet Telephony Bandwidth Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Internet telephony technologies face challenges in expanding services and improving quality of service, particularly in bandwidth efficiency and cost reduction for network communication.
Innovation Solution
A proxy server system is introduced, connecting two service networks with a system manager and database, enabling internal and external account management, session process management, and signal routing to provide shared network services, reducing the need for direct registration with ISPs and optimizing bandwidth usage through transcoding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If each node directly registers with the ISP to obtain external account services, then each node can independently access external network services, but the system complexity increases and bandwidth efficiency decreases
Solution Approach 1:
The proxy server acts as an intermediary between internal nodes and the external ISP. Instead of each node directly registering with the ISP, the proxy server consolidates registration and manages external account access on behalf of multiple nodes. This reduces system complexity while maintaining service accessibility, as the proxy server handles authentication and session management centrally.
Solution Approach 2:
Multiple internal nodes are merged into a single external account through the proxy server. The proxy server aggregates the registration and session management for multiple nodes under one external account, reducing the number of external connections and simplifying the system architecture while allowing all nodes to access external services.
2Ease of operation
If multiple nodes register separately with the ISP, then each node has independent service access, but bandwidth usage increases and cost efficiency decreases
Solution Approach 1:
The proxy server combines multiple internal node sessions into shared external connections to the ISP. By merging the external account access, the system reduces redundant bandwidth consumption that would occur if each node maintained separate external connections, while still allowing independent service access for each node through the shared proxy infrastructure.
3Loss of energy
If the proxy server manages external account for multiple nodes, then bandwidth efficiency improves and cost reduces, but the device complexity increases
Solution Approach 1:
The proxy server is designed with multi-functional modules that handle various aspects of external account management: the external registrar module manages registration, the session manager module handles session processes, and the signal routing module manages signal routing. This modular universal design allows the single proxy server to efficiently manage multiple nodes' external access, improving bandwidth efficiency while organizing complexity into manageable functional components.

AI summary
A proxy server including a system manager and a database is provided. The system manager includes an internal registrar module, an external registrar module, a session manager module and a signal routing module. The internal registrar module provides an internal register service for a plurality of nodes in a first service network. The external registrar module registers at an internet service provider providing network services in a second service network. The session manager module manages session processes in the first service network and the second service network and manages the network services shared between the registered nodes. The signal routing module routes control signals of the session processes between the first service network and the second service network. The database stores information related to the registered nodes.
