Network Transceiver System for Multimode Internetworking Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network systems are unable to concurrently support multiple Internet Service Providers (ISPs) and internetworking environments, lacking the ability to provide secure, connection-oriented, and dedicated-media internetworking while being vulnerable to security threats due to shared-media and connectionless IP-based networks.
Innovation Solution
A novel network transceiver system that enables concurrent subscription to multiple ISPs and Application Service Providers (ASPs) across disparate internetworking environments, using multi-carrier bands or Virtual Connection Circuits (VCC) for bandwidth allocation, and incorporating a Media Adaptation Layer (MAL) for end-to-end circuit-switching, supporting both shared-media and dedicated-media internetworking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If shared-media and connectionless IP-based networks are used, then network connectivity is provided, but security vulnerabilities increase due to lack of connection-oriented communication
Solution Approach 1:
The patent segments the network communication into two distinct modes: connection-oriented mode for secure communication and connectionless mode for standard IP networking. This segmentation allows the system to provide both security benefits of circuit-switching and versatility of IP-based networking without compromising either aspect.
Solution Approach 2:
The network device is designed with multi-functionality to support both connection-oriented and connectionless internetworking modes simultaneously. It can subscribe to multiple ISPs and service providers while maintaining the ability to provide secure dedicated-media connectivity when needed, thus achieving universality across different network requirements.
2Adaptability or versatility
If single ISP connectivity is provided, then network setup is simple, but adaptability to multiple service providers is limited
Solution Approach 1:
The network device incorporates universal capabilities to subscribe to and manage multiple ISP connections simultaneously. It maintains a plurality of communication channels to different service providers while presenting a unified interface for management, thus achieving multi-ISP adaptability without proportionally increasing operational complexity.
Solution Approach 2:
The patent introduces an intermediary management layer that handles the complexity of multiple ISP subscriptions and connections. This intermediary structure abstracts the complexity of managing multiple service providers from the end user, allowing versatile multi-ISP connectivity while maintaining simplified configuration and control.
3Reliability
If connectionless IP-based routing is used, then network flexibility is improved, but security and connection-oriented services deteriorate
Solution Approach 1:
The system segments communication protocols into connection-oriented and connectionless modes, allowing application-specific selection. This enables secure connection-oriented services for sensitive traffic while maintaining ease of operation through automatic protocol selection for standard IP-based applications, thus resolving the contradiction between reliability and ease of operation.
