thank you for choosing d-link dge-550t, the value leader among dual-speed adapters for pci bus personal computers. this introduction gives a general description of the newer networking technologies found on the dge-550t.

    the dge-550t provides the bandwidth capability to support high-end servers and workstations. with autonegotiation, this card can run on three different speeds: 10/100mbps, both half- and full-duplex, and 1000mbps at full duplex. when running at 1000mbps, it provides a network throughput of 2gbps in full-duplex mode.

    the card supports ieee 802.1p traffic prioritization for time-sensitive and mission-critical traffic. with ieee 802.1q multiple vlan support, it provides vlan tables that can filter packets by recognized vlan tags, strip vlan tags when received, and insert vlan tags when transmitted. vlans can increase the efficiency and provide extra security of your network.

    the dge-550t provides ieee802.3x flow control enhancements, which are needed for a network adapter to function with a switch. in full-duplex mode, mac implements the pause control function. this means when a switch is connected in full-duplex mode and it senses that its buffer will overflow in the near future, the switch will transmit one standard ethernet packet that causes the dge-550t to pause for a period, thus avoiding internal buffer overflow and packet loss.

    the nic enables simple, scalable network migration, providing the benefit of gigabit ethernet networking with the familiarity of ethernet.
