MPLS Virtual Private Network Service Delivery via Intermediary Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current approaches to providing virtual private networks (VPNs) face challenges such as high costs, complex implementation, unreliable performance, low security, and difficulty in managing and monitoring services across disparate service providers, leading to inefficiencies and service disruptions.
Innovation Solution
A system and method for constructing a virtual private network that utilizes Multi-Protocol Label Switching (MPLS) and Ethernet technology to create a deterministic transport infrastructure, enabling standardized interconnections of dissimilar service provider technologies, performing quality-of-service management, and allowing for passive and active measurement and testing throughout the network, while minimizing integration and coordination efforts among participants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated private communication connections are used to interconnect company offices, then network security and centralized control are improved, but total cost and resource utilization efficiency deteriorate
Solution Approach 1:
The patent introduces a service provider as an intermediary to own and manage the private network infrastructure, while corporations lease virtual access to specific network segments. This mediator approach allows corporations to enjoy secure private network benefits without bearing the full cost of ownership and management, resolving the contradiction between security and cost.
Solution Approach 2:
The patent segments the physical network infrastructure into multiple virtual networks, allowing different corporations to lease specific segments or virtual channels. This segmentation enables efficient resource utilization by serving multiple customers from a single physical infrastructure, reducing total cost while maintaining dedicated security boundaries for each customer.
2Device complexity
If the Internet is used as a transport mechanism for business applications, then cost and convenience are improved, but security and performance reliability deteriorate
Solution Approach 1:
The patent implements local quality by providing each corporation with a customized virtual network segment tailored to its specific security and performance requirements. Each virtual segment can have differentiated security policies, quality of service parameters, and access controls, allowing corporations to achieve Internet-like cost efficiency while maintaining private network-level security through locally optimized virtual environments.
3Adaptability or versatility
If service providers collaborate to extend VPN service reach beyond their own infrastructure, then service coverage is improved, but implementation complexity and coordination effort deteriorate
Solution Approach 1:
The patent creates a universal service delivery platform that can accommodate multiple service providers and their respective virtual network segments. The system provides standardized interfaces and protocols that enable different providers to interconnect their networks without complex customization, allowing service coverage to be extended through collaboration while keeping implementation complexity manageable through universal standards.
