What can I do to enable automatic switching to a backup network when there is packet loss?

If I create a connection using network bonding (using the mode active-backup), then although automatic switching to the backup network occurs if I pull out the network cable, it does not occur when the problem is no packets getting through. What can I do to enable automatic switching to the backup network when there is packet loss on the primary with switching back when the primary is working properly (much like how network bonding with mode active-backup seamlessly switches between primary and backup and back when pulling out and plugging back in the network cable)?
