•
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-550TX 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-
550TX. The ensuing idle time keeps the buffer from overflowing
and prevents data from being lost. This enhancement can improve
network throughput, avoid collisions and prevent lost data,
helping the network achieve optimal performance.
IP Multicasting
The
DFE-550TX
implementing IP Multicasting (defined in RFC 1112). This
hardware-based implementation provides a huge performance
increase over other interface cards. Formerly, broadcast packets
were used for multicasting, but they are a less than ideal solution
for transmitting packets to groups. This is because broadcast
packets reach every terminal on the network, creating undue
traffic and occupying CPU time on all computers.
IP Multicasting is a much better way to send data to groups,
