Introduction2
While powered-down computers Sleep, WOL enabled NICs
monitor LAN traffic for valid Wake-up frames. When one is
received, the NIC will immediately wake-up and send a
signal to the motherboard to power ON the computer.
Some uses for the WOL feature include:
•
Forgot a document and out of town? Send a Wake-up
signal to your computer and retrieve the needed file.
•
Initiate long routines and reports before you get to
work.
•
Transfer files when the network traffic is low (during
late hours).
•
Power ON your PC before you arrive to work.
•
The MIS department can upgrade software on
computers after hours from a remote station.
WOL is very helpful in limiting the power consumption of
PCs, workstations, and kiosks.
Flow Control
The DFE-530TX implements IEEE 802.3x compliant flow
control for full duplex, which provides traffic management
functions for full-duplex operation. Flow control allows for
enhanced full duplex operation with switches. When
operating at full duplex (requiring a direct connection to a
switch) and the switch’s data buffer is about to overflow, a
Pause frame will be transmitted to the DFE-530TX. The
ensuing idle time keeps the buffer from overflowing and
prevents data from being lost. This enhancement can
improve overall network throughput, prevents lost data and
helps the network achieve optimal performance.
