Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In data communication networks, migrating services while minimizing disruption and adhering to hardware and software resource constraints is challenging, particularly due to overlapping service routes and limited resource availability.
Innovation Solution
A method and system for migrating communications services by accessing a migration map to identify dependencies and determine a sequence that allows no more than M services to migrate simultaneously, ensuring smooth transitions and resource optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If services are migrated simultaneously to optimize resource usage, then resource optimization is improved, but service disruption increases and system stability deteriorates
Solution Approach 1:
The patent segments the service migration process by introducing a migration sequence that limits the number of services migrating simultaneously to a threshold value. This segmentation divides the migration into controlled batches, preventing system overload and maintaining stability while still achieving resource optimization through coordinated migration of multiple services.
Solution Approach 2:
The patent implements dynamic control of the migration process by adjusting the migration sequence based on system state. The system dynamically determines which services migrate when, using criteria such as service dependencies, resource availability, and current system load, thereby balancing resource optimization with service disruption minimization.
2Speed
If more services are allowed to migrate simultaneously, then migration speed is improved, but resource constraints are exceeded and system stability worsens
Solution Approach 1:
The patent applies preliminary action by pre-calculating and determining a migration sequence before execution. The system analyzes service dependencies, resource requirements, and constraints in advance to create an optimized migration plan, allowing faster migration execution without exceeding resource limits during the actual migration process.
3Productivity
If services with overlapping routes are migrated together, then resource optimization is improved, but service disruption increases
Solution Approach 1:
The patent introduces an intermediary mechanism in the form of a migration sequence that mediates between services with overlapping routes. This intermediary controls the timing and order of migrations, coordinating services that share network paths to minimize mutual interference and service disruption while still achieving resource optimization through coordinated migration.

AI summary
Techniques for migrating a plurality of communications services in a data communication network are disclosed. Aspects include accessing a migration map for the plurality of communications services; identifying a communications dependency between a first service and a second service according to the migration map, the first service migrating from a first route to a second route, the second service migrating from a third route to a fourth route, and the third route at least partially overlapping with the second route; determining a migration sequence based on the communications dependency, wherein the migration sequence includes a largest subset of the plurality of communications services of which no more than M communications services are allowed to migrate from pre-migration configurations to temporary routes, before migrating to post-migration configurations; and migrating the plurality of communications services from a first plurality of configurations to a second plurality of configurations according to the migration sequence.
