The invention discloses a
distributed computing task non-
perception migration method and
system under
optical fiber network interruption. The
distributed computing task non-
perception migration method comprises the following steps: constructing a distributed task migration
system and an output
system architecture; collecting network state indexes, constructing a network
topological graph, and analyzing the state of an
optical fiber link for fault prediction; obtaining a calculation task operation state, establishing a sub-
task mapping relation, constructing a directed
dependency graph, and generating a state snapshot; analyzing resource requirements, reserving standby resources, and deploying a
distributed cache system; analyzing a fault influence range, extracting an influenced calculation sub-graph, and selecting a migration target node; in a target node preloading environment, reconstructing an execution context, and redirecting a communication path; and setting a data change capture mechanism,
synchronizing incremental data and executing consistency
verification. According to the method, non-
perception migration of the computing tasks is realized, task continuity and
data consistency are guaranteed, and the reliability of the
distributed computing system in an
optical fiber network fault scene is improved.
