Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
After a network entity moves, existing systems fail to efficiently propagate the movement event message to network devices responsible for data transmission, leading to potential disruptions in data transmission performance and service continuity.
Innovation Solution
A method involving network devices that maintain an uplink port information table and historical forwarded information list to identify and propagate movement event messages by matching network entity names and addresses, ensuring timely notification and subsequent processing to improve data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a network entity moves and its IP address changes, then the network entity can maintain location independence through ICN naming mechanism, but existing systems fail to efficiently propagate movement event messages to network devices responsible for data transmission
Solution Approach 1:
The patent applies preliminary action by having network devices pre-establish uplink port information tables and historical forwarded information lists before movement events occur. These data structures are prepared in advance with the necessary forwarding information, enabling immediate message propagation when a movement event occurs, thus reducing propagation delay while maintaining service continuity
Solution Approach 2:
The patent implements feedback mechanisms where network devices monitor and detect movement events, then propagate movement event messages back to relevant network devices. The system continuously updates forwarding information based on detected movements, creating a closed-loop feedback system that maintains accurate routing information and ensures timely message delivery to the correct network devices
2Loss of information
If movement event messages are propagated to all network devices, then all devices are informed of movements, but network traffic and processing overhead increase
Solution Approach 1:
The patent applies local quality by making forwarding information specific to each network device and its local context. Each device maintains its own uplink port information table and historical forwarded information list tailored to its specific forwarding needs. Movement event messages are propagated only to devices that have relevant local forwarding information, ensuring information completeness for affected devices while avoiding unnecessary propagation to devices without local relevance, thus reducing network traffic overhead
Solution Approach 2:
The patent segments the network into individual device contexts, where each device independently maintains its own forwarding information structures. This segmentation allows the system to propagate movement event messages selectively to only those devices that need the information based on their local forwarding tables, rather than broadcasting to all devices. The segmentation enables precise control over message propagation, maintaining information completeness for relevant devices while minimizing energy consumption from unnecessary message transmission

AI summary
The present invention provides a method for propagating a movement event message of a network entity, including: step 1) a network device maintaining a historical forwarded information list, wherein a network device capable of receiving a movement event message from an external system or device also maintains an uplink port information table; step 2) after receiving the movement event message sent by the external system or device, the network device with the uplink port information table performing matching by using the uplink port information table to obtain a forwarding port and forwarding information of the movement event message, and constructing a movement event forwarding message by using the forwarding information and forwarding same through the forwarding port; and step 3) after a network device receives the movement event forwarding message, searching for a matching forwarding port and forwarding information of the movement event forwarding message in the historical forwarded information list, modifying the movement event forwarding message by using the forwarding information, and then forwarding the modified movement event forwarding message through the forwarding port. The method of the present invention is able to propagate a movement event message to a network device responsible for related data transmission and forwarding.
