Target Applications
Enterprise Access/Aggregation
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.

Bandwidth Control)
Multiple users/services per port, with bandwidth limit and guaranteed
bandwidth (Three Color Marker & Policing)
Two Rate Three Color Market & Policing
• Committed Information Rate (CIR): Guarantees the bandwidth of each
service by limiting the bandwidth of each other.
• Peak Information Rate (PIR): Allows services to take
the unused bandwidth for better bandwidth usage.
VoIP
• Traffic Policing: Drops or remarks the packet
priority tag for traffic exceeding CIR. Doing
best-effort forwarding when peak of each
service are conflicted.

Traffic Shaping
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.

Smoothed Deficit Weighted Round Robin (SDWRR)
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.

Virtual Private Wire Service (VPWS)
Compatible with existing MPLS network, using LDP for label switching
Transparency of subscriber’s L3 routing protocol in ISP network, reduces the
effort of ISP and also provides better extensibility in subscriber networks
Co-works with QinQ and L2PT to provide L2 transparency to customers

Switch Resource Management (SRM)
Switch Resource Management templates allow user optimizing the switch
databases for different application.
• Routing Mode: For applications requires larger routing tables such as company gateway
• VPWS Mode: For applications requires lots of L2 VPN tunnels such as ISP access switch

Cable Diagnostics
Change pair, no need to change cable
• Usually multi-pair cables are used for the network
construction of cabinets or buildings
• Detecting various of errors
-
Lines of specific pair is left open
Two lines of a pair is shorted
Lines of different pair are short
Cable does not exist or quality is too bad
Locating the position of cable errors, saving time on
cable repair Note
Note: DES-3810 supports distance check on GE port only
