Definitions for "Hot standby"
Backup equipment kept turned on and running in case some equipment fails
See standby.
A strategy that uses two PacketShaper/AppVantage units connected in parallel, with one unit active and the other acting as a hot spare. In the event of a failure in the active unit, the spare unit takes over automatically, using the same IP address. Hot standby should not be confused with the failover feature, a process that adjusts link rate when a router switches to a backup WAN connection.
