Transfer Apparatus Cost Differential Routing for Network Migration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The migration of services in communication networks leads to increased control load and instability due to the lack of efficient communication route management during network transitions, as existing methods do not account for migration to new communication networks.
Innovation Solution
A transfer apparatus is introduced that sets costs for data transfer lines and calculates differential costs to reroute data through a new node, reducing the load on controlling communication networks by selecting routes with lower costs, thereby stabilizing network migration processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If communication networks migrate services to new networks, then network adaptability and versatility improve, but control load increases and stability deteriorates
Solution Approach 1:
The transfer apparatus performs preliminary calculations of total costs and differential costs before actual route changes occur. By pre-calculating the cost differences between existing routes and new routes, the system can make informed decisions about route migration, avoiding unstable control during the transition process.
Solution Approach 2:
The system dynamically adjusts cost parameters between transfer apparatus and lines based on calculated differentials. By modifying cost values as parameters, the system guides data flow along optimal routes during migration without requiring complex control mechanisms, thereby maintaining stability while achieving adaptability.
2Adaptability or versatility
If communication networks migrate services to new networks, then network adaptability and versatility improve, but control load increases
Solution Approach 1:
The transfer apparatus autonomously calculates costs and determines optimal routes without requiring extensive external control. Each apparatus independently computes total costs and differential costs, making self-directed decisions about data routing during migration, which reduces the overall control load on the network.
Solution Approach 2:
By using cost parameter adjustments to guide routing decisions, the system achieves efficient control. The calculated differentials are used to modify cost parameters, which automatically directs data flow to optimal paths, simplifying the control process and improving productivity during migration.
3Productivity
If cost values are dynamically adjusted to change routes, then route optimization improves, but device complexity increases
Solution Approach 1:
The cost calculation process is segmented into distinct steps: calculating total cost of the first route, obtaining particular cost of the second route, calculating differential cost, and setting new cost values. This segmentation simplifies the overall complexity by breaking down the route optimization process into manageable, sequential operations.
Solution Approach 2:
The differential cost acts as an intermediary value that bridges the existing route costs and the desired new route costs. By using this intermediate calculation, the system can determine appropriate cost adjustments without directly comparing complex route configurations, thereby reducing the apparent device complexity while maintaining route optimization efficiency.

AI summary
A transfer apparatus (203) is configured to: calculate a total cost of a first route in a first network that starts from a source transfer apparatus and ends at a destination transfer apparatus; obtain a particular cost being a cost between the source transfer apparatus and a first line, which couples the source transfer apparatus and its own transfer apparatus, in a second route, which starts from the source transfer apparatus (203) and reaches the destination transfer apparatus via its own transfer apparatus; calculate a differential between the total cost and the particular cost; set, based on the differential, a cost between its own transfer apparatus (203) and a second line, which couples its own transfer apparatus and the destination transfer apparatus, to a value that causes the source transfer apparatus to select the second route rather than the first route; and notify the cost value to the source transfer apparatus.
