Layer-2 Pseudo-Wire Rapid Deployment Over Unknown IP Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Telco Layer-2 services are limited by requiring provisioning across Telco core networks with interconnect agreements, taking 30-90 days to implement, and are difficult to provide in areas not served by the Telco's infrastructure, with mismatched features and interfaces between carriers, making rapid deployment and interconnection challenging.
Innovation Solution
A method and system for rapid deployment of Layer-2 Pseudo-wire services using Provider-Edge and Provider-Core appliances to establish PSN-Tunnel connections over unknown Internet Protocol networks, enabling almost instant Layer-2 connectivity across disparate networks via any available physical media, including the public Internet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional Telco Layer-2 services are provisioned across Telco core networks with interconnect agreements, then service reliability is improved, but deployment time increases to 30-90 days
Solution Approach 1:
The patent introduces PSN tunneling technology as an intermediary mechanism that enables Layer-2 connectivity over public Internet networks without requiring traditional Telco core network infrastructure or interconnect agreements. This mediator allows direct peer-to-peer connectivity while maintaining service reliability, eliminating the 30-90 day deployment timeline associated with traditional Telco provisioning processes.
Solution Approach 2:
The patent replaces the mechanical/manual provisioning process of traditional Telco services with automated software-based PSN tunneling. Instead of manual configuration and physical infrastructure setup taking 30-90 days, the system uses automated tunnel establishment over IP networks, reducing deployment time to minutes or hours while maintaining connection reliability through encrypted tunnel protocols.
2Stability of the object's composition
If traditional Telco services are used, then network stability is improved, but adaptability to unknown networks deteriorates
Solution Approach 1:
The patent creates a universal Layer-2 connectivity solution that functions across multiple network types including public Internet, private IP networks, and unknown networks. The PSN tunneling mechanism provides multi-functional adaptability, allowing the same technical approach to work across different network infrastructures without requiring Telco-specific agreements or proprietary infrastructure, thus achieving both stability and versatility.
3Reliability
If Telco infrastructure is required, then service quality is improved, but device complexity increases
Solution Approach 1:
The patent extracts the essential Layer-2 connectivity function from the complex Telco infrastructure and implements it directly through PSN tunneling at the network edge. By removing the requirement for Telco core network infrastructure, interconnect agreements, and complex provisioning systems, the solution maintains service quality while dramatically reducing infrastructure complexity to simple edge devices capable of establishing encrypted tunnels over standard IP networks.
