Abstract
A method is provided for migrating a connection between two computing nodes of a computing center. The method includes establishing the connection between a remote application and a local application on a first computing node, pausing the local application, restoring the local application to a second computing node, and reestablishing the connection between the remote application and the local application on the second computing node. A connection filter on the first computing node can maintain connections while the local application is paused. An application scheduler routine can cause the application to be restored on the second computing node where a second connection filter obtains connection information and reestablishes the connection to the remote application.
