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 uses chip-level address filtering when
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
