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, 
especially since routers and even switches can filter packets so 
they only reach those stations that are part of the group. The 
DFE-550TX goes one step further by examining multicast 
packets on the card itself (rather than using the computer’s 
CPU) and only accepting those packets for the group(s) in 
which the host belongs, thus conserving CPU utilization.  
This can be very useful since more and more multicast data, 
such as corporate messages to employees, stock quotes, video 
and audio conferencing, and database replication is 
transmitted on today’s networks.  
IP Multicasting can eliminate an organization's need to 
maintain parallel networks for voice, video and data. 
DMI/Desktop Management Interface 
DMI is an Operating System/Network Operating System-
independent management framework that allows system 
vendors to support multiple market/customer segments with a 
single management strategy. DMI lowers the Total Cost of 
Ownership (TCO) by providing a common framework for 
managing desktop systems, mobile systems and servers. 
DMI supports a management schema (Management 
Information Format [MIF]), allowing manageable components 
to be described within various platforms in a standard 
descriptive language. MIFs are extensible, allowing the DFE-
550TX to export value-added management capabilities. These 
value-added management features enable remote 
troubleshooting and higher quality management of computer 
resources.
