When a file is transferred over a WAN, say from a head office to a branch office, a copy of it is cached by the branch office's WOC.
The backup rules allow traffic to go through the ISP that has connectivity in case either were to fail.
WAN optimization controllers (WOCs) can breathe new life into slow wide area network links, relieving congestion, speeding up file transfers and making applications more responsive.
In some circumstances the amount of data traveling over a WAN can be reduced by 75 percent or more using data reduction techniques.
Latency, as mentioned earlier, can be a problem with WANs.
