Target Applications Enterprise Access/Aggregation

DES-3810 Stack

DES-3810

ECMP & PBR provides redundant/load sharing capability of uplink.

IMPB, ARP Spoofing Prevention, DHCP Server Screening, BPDU Attack Protection, and L3 Control Packet Filtering expel threats out of core networks.

MAC, WAC, and Compound authentication provide clientless/easy-to-deploy mechanisms to authenticate users and devices.

Embedded DHCP server, auto-configuration, and trap/e-mail alerts make the network management much easier.

Technology BriefingBandwidth Control & Three Color Marker

D-Link Confidential

To lower the packet lose rate, almost all switch controllers have built-in expensive buffer memory to prevent the data re-transmission.

Switch stores the traffic in buffer memory and delays the transmission until the egress bandwidth is available.

However, the best-effort traffic shaping is no longer enough for the QoS requirement nowadays.

Accurate and fair scheduling is required to make the egress bandwidth usage more proper nowadays• Fair Queue (FQ), WFQ, Deficit Round Robin (DRR), WDRR: Forward/scheduling

decision made by byte count and utilization of queues, the true weight of each queue.

• Smoothed round-robin mechanism makes rapid passes for each queue and use more turns for high queues instead of waiting all packets transmitted in high queues.
