Dynamic Pseudo-Link Establishment in VPLS Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current VPLS services using MPLS technology are inflexible and inefficient, as they establish fixed pseudo-links between LAN networks, which do not adapt to changing communication needs, such as during base station handovers, and consume unnecessary network resources.
Innovation Solution
A communication method that dynamically establishes pseudo-links between termination devices based on client equipment identifiers, allowing for adaptive data transfer plans and efficient resource allocation, including the option to destroy pseudo-links when not in use to conserve resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed pseudo-links are established between all termination devices in VPLS service, then network connectivity is ensured, but network resources are wasted and flexibility is reduced
Solution Approach 1:
The patent implements dynamic pseudo-link establishment where links are created on-demand based on actual communication needs between client devices. The system monitors communication requests and establishes pseudo-links only when necessary, rather than maintaining fixed pre-configured links. This dynamic approach ensures connectivity reliability while eliminating waste of network resources on unused links.
Solution Approach 2:
The system changes the state parameter of pseudo-links from static/permanent to dynamic/temporary. Pseudo-links are established with specific lifecycle parameters including creation time, expiration time, and usage conditions. This parameter change allows the network to adapt link configurations dynamically, maintaining connectivity when needed while releasing resources when links are not in use.
2Device complexity
If fixed pseudo-links are established between all termination devices, then network architecture is simplified, but adaptability to changing communication needs is reduced
Solution Approach 1:
The patent introduces dynamic pseudo-link establishment that adapts to changing communication requirements. When new communication needs arise (e.g., during base station handovers), the system automatically establishes appropriate pseudo-links. This maintains architectural simplicity through automated procedures while achieving high adaptability to dynamic network conditions and communication patterns.
Solution Approach 2:
The system implements self-service automation where the network automatically detects communication needs and establishes pseudo-links without manual intervention. The automated procedure monitors communication requests between client devices and dynamically creates necessary network paths, combining architectural simplicity with operational flexibility.
3Reliability
If pseudo-links are maintained continuously, then connection reliability is improved, but data transmission time increases due to unnecessary link maintenance
Solution Approach 1:
The patent implements periodic evaluation of pseudo-link necessity rather than continuous maintenance. The system periodically checks whether active communication requires specific pseudo-links and establishes or removes links accordingly. This periodic action maintains connection reliability for active communications while avoiding time delays associated with maintaining unnecessary links.
Solution Approach 2:
The system discards (removes) pseudo-links when they are no longer needed for active communications and recovers network resources for future use. Pseudo-links are established temporarily for specific communication sessions and removed afterward, eliminating the time penalty of maintaining permanent links while ensuring reliability during actual data transmission.
