CDP

1. Cisco Discovery Protocol. A proprietary network protocol developed and used by Cisco, which is used to share network information between network devices.

2. Continuous Data Protection. A backup system which backs up changes to data and files as soon as that change has been made. This allows files and data to be recovered to any point in time. In theory this should provide virtually no data loss should files or data need to be restored from a backup.
