Process migration in data center networks

摘要

There is provided a method and system for process migration in a data center network. The method includes selecting processes to be migrated from a number of overloaded servers within a data center network based on an overload status of each overloaded server. Additionally, the method includes selecting, for each selected process, one of a number of underloaded servers to which to migrate the selected process based on an underload status of each underloaded server, and based on a parameter of a network component by which the selected process is to be migrated. The method also includes migrating each selected process to the selected underloaded server such that a migration finishes within a specified budget.

1. A method for process migration in a data center network, comprising:
selecting, via a computing device, processes to be migrated from a plurality of overloaded servers within a data center network based on an overload status of each overloaded server; selecting, via the computing device, for each selected process, one of a plurality of underloaded servers to which to migrate the selected process based on an underload status of each underloaded server, and based on available capacities for network links by which the selected process is to be migrated, wherein the process to be migrated and the underloaded server to which to migrate the process are selected simultaneously by performing a first linear programming relaxation to produce a fractional solution and a second linear programming relaxation on the fractional solution to produce an integral solution; and migrating, via the computing device, each selected process to the selected underloaded server based on the integral solution such that a migration finishes within a specified budget of time.
