Totem is based on circulating token and lost of token (so token was not delivered for given time) is used as failure detector (so weak detector). Corosync also implements (optionally) hearth beating. For more informations take a look to: https://github.com/corosync/corosync/wiki/Developers#reference-documentation Especially http://corosync.github.com/corosync/doc/DAAgarwal.thesis.ps.gz should give you informations you need.
