linux - Is it possible to put foreground process into background without suspending (control +z)?

I am running an application which receives TCP and UDP packets and therefore cannot be suspended. I intially ran 3 processes of the same application, with different arguments, in background mode using &. When I did only $fg, all three process came into foreground. Now I want to send them to background again but without suspension. How can I do that?
