ABSTRACT:
Hitless Switching provides a method of delivering data to a remote point in a reliable fashion. However, no guarantee or acknowledgement is provided that data has been written to a remote storage device. This is problematic for remote data mirroring. Apparatus and methods are provided to guarantee that data arriving at a remote terminal is correctly stored. Interaction with hitless switching and remote optical mirroring systems are described.
