Synchronization between LinuxDirector and Backup

["Chul Lee" <chullee@xxxxxxxxxxxxxxxx>]

Hello List

Currently, LVS uses redundant backup LinuxDirector for fail-over .
However, current implementation is said to cause the established connection
lost
and let the client  send their requests again.

Is there any efforts to perfom LinuxDirector's failover without lost of the
established connection?
I think that Backup director can be synchronized with the LinuxDirector with
the help of TCP tapping techniques. Therefore Backup and LinuxDirector see
almost same hash tables(may not 100% identical).

Please, point me to the related efforts or projects.

Chul
