Method, system and computer program product for transitioning network traffic between logical partitions in one or more data processing systems

Abstract

A method, system and computer program product for transitioning network traffic between logical partitions in one or more data processing systems are disclosed. The method includes defining a plurality of logical partitions with respect to one or more processing units of one or more data processing systems and dynamically reallocating resources from a second partition to a first partition among the plurality of logical partitions. Packets awaiting processing are transferred from the second partition to the first partition and processed on the first partition.

AI Technical Summary

Benefits of technology

[0014] A method, system and computer program product for transitioning network traffic logical partitions in one or more data processing systems are disclosed. The method defining a plurality of logical partitions with respect to one or more processing units of more data processing systems and dynamically reallocating resources from a second to a first partition among the plurality of logical partitions. Packets awaiting processing are red from the second partition to the first partition and processed on the first partition.

Problems solved by technology

The ability of a partitioned data processing system both to create and to close or dissolve concurrent instances of one or more operating systems on a single processor creates numerous technological challenges with regard to the migration of resources and processes from one partition to another.
