Proxy Node Access Network Virtualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing management systems for access networks face increased operation and maintenance costs and service disruptions when adding a new type of access network node, such as FTTDp, as they require modifications, affecting user experience and network usability.
Innovation Solution
A method for access network virtualization using a proxy node that establishes a relationship mapping table to map virtual access nodes to remote access nodes, allowing packets to be routed without modifying the existing management system, thereby reducing operational costs and integration time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a new type of access network node (FTTDp) is added to the original network, then the network coverage and service capability are improved, but the management system needs to be modified which increases operation and maintenance cost
Solution Approach 1:
A proxy node is introduced as an intermediary between the management system and remote access nodes. The proxy node receives management packets from the management system, queries the mapping table to obtain the corresponding remote access node, and forwards the packet to the target node. This intermediary approach allows the management system to remain unchanged while supporting new access network node types through the mapping table mechanism.
Solution Approach 2:
The patent creates a virtual mapping table that maps virtual access node identifiers to actual remote access node identifiers. This copying mechanism allows the management system to manage virtual nodes rather than physical nodes directly, enabling flexible addition of new node types without modifying the management system structure.
2Adaptability or versatility
If the management system is modified to support new access network nodes, then the system functionality is improved, but service interruption occurs affecting user experience
Solution Approach 1:
The mapping table is pre-configured with the correspondence between virtual access nodes and remote access nodes before new nodes are deployed. This preliminary setup allows the system to immediately support new nodes without requiring live modifications or service interruptions, as the mapping relationships are already established and ready for use.
3Measurement precision
If multiple remote access nodes are managed individually, then the management precision is improved, but the operation and maintenance cost increases
Solution Approach 1:
Multiple remote access nodes are merged under a single virtual access node identifier in the mapping table. The management system manages the virtual node as a single entity, while the proxy node handles the distribution of management packets to multiple actual remote access nodes based on the mapping table. This combining approach reduces management complexity while maintaining precise control over individual nodes.
