Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network management systems fail to account for real-time outages and degradation of services on remaining links during maintenance, leading to potential service degradation.
Innovation Solution
A method and system that adaptively manage network capacity by receiving simulation data periodically, adjusting the periodicity based on the time until a communication link is taken offline, and moving load to alternate links that satisfy predetermined criteria, using a processor and memory with instructions to execute these operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If simulation data is received periodically to analyze link outage impact, then network service degradation can be mitigated, but the timing and frequency of data reception must be optimized to balance accuracy and system resources
Solution Approach 1:
The patent applies dynamics by making the data reception periodicity adaptive rather than fixed. The system dynamically adjusts the frequency of simulation data reception based on the time remaining until a planned link outage, receiving data more frequently when the outage is imminent and less frequently when there is more time, thus optimizing the balance between service quality and time resources
Solution Approach 2:
The patent changes the parameter of data reception periodicity based on the time interval to link outage. By modifying this temporal parameter dynamically, the system optimizes when simulation data should be collected and analyzed, ensuring sufficient preparation time while reducing unnecessary delays in critical situations
2Reliability
If load is moved to alternate communication links before maintenance, then service degradation is reduced, but the decision requires evaluation of multiple links against predetermined criteria
Solution Approach 1:
The patent applies preliminary action by evaluating alternate communication links and preparing load migration plans before the actual link maintenance occurs. The system proactively identifies suitable alternate links and validates them against predetermined criteria in advance, ensuring service continuity is maintained when the maintenance event happens
Solution Approach 2:
The patent implements feedback mechanisms where simulation data about link performance and alternate paths is continuously collected and evaluated. This feedback information is used to adjust load migration decisions, ensuring that the selected alternate links truly satisfy the predetermined criteria for maintaining service quality

AI summary
A method, system and machine-readable storage device to manage network capacity are provided. In accordance with the method, simulation data is received periodically according to a metric based on data associated with a plurality of communication links interconnecting endpoints. Specially, the simulation data is received according to a periodicity adjusted selectively based on an interval of time between a current date and time and a date and time that a communication link is to be taken offline. The simulation data indicates impact of the communication link to be taken offline on a plurality of alternate communication links. Thereafter, load is moved selectively from the communication link to be taken offline to an alternate communication link of the plurality of alternate communication links based on whether the simulation data associated with the alternate communication link satisfies a predetermined criterion.
