Backup node in embodiment determines that method comprises the steps:
Step s101: judge whether the window number that current window pattern includes is more than 1, if window number is more than 1, enter step
S102, if described window number is equal to 1, enters step s106；
One window scheme can include multiple windows, typically corresponding with same application, opens on combination
One window scheme, corresponding each window opening it and including；
Step s102: choose a window successively from each described window as target window；
In advance each window can be numbered, according to number order successively selected window it is also possible to be selected
Window be marked, randomly select from unmarked window every time, or delete the window that had been selected, here
It will not go into details；
Select a target window every time, that is, execute steps s103～step s105 (according to step s103
Judged result or execution step s103, step s104, or execution step s103, step s105)；
Step s103: judge whether the occupancy nodes of described target window are more than 1, if described occupancy nodes are more than 1,
