Usually fan module has lower MTBF value. The lower fan speed can extend the life time of fan module. Once the fan module’s MTFP is improved, the whole system’s MTBF will be improved, too. 5

6. Product Overview Premium Offerings of DGS-3620 xStack Switches
Investment Protection
Multiple functions (L3 routing, high port density, security and PoE) in a single device, eliminating the needs of purchasing multiple router and switches
Future-proofing IPv6 features
Ultra High Performance
Up to 4 10G uplink ports allow maximum 40G backbone bandwidth
Maximized Network Uptime
Resilient switching & routing technologies (OSPF, VRRP, MSTP, ERPS, LACP..)
Physical stacking architecture avoids single point of failure
Redundant power supply design
Application Awareness
VoIP-enabled network by Voice VLAN, which auto recognizes VoIP devices & prioritizes their traffic
PoE models available for easy deployment of VoIP networks
Committed bandwidth for mission critical applications
Physical stacking supports ring architecture. When 1 device in the stack fails, the traffic can go over another path in the ring to the destination. The path switchover time is much faster than RSTP.
Cross-stack link aggregation provides uplink redundancy. In a stack, when 1 switch with uplink connection fails, other switches with uplink connections still provide service. 6

7. Product Overview Premium Offerings of DGS-3620 xStack Switches
Comprehensive Security
A variety of Endpoint Security features (authentication & attack mitigation, etc)
Not only as a core/aggregation switch, but allows for endpoint connections
Ease of Management
DGS-3620’s Web GUI supports FULL SET of features, good for first timer
12 DGS-3620 devices can be stacked as a single unit, easing the management effort
Virtually stacks with other D-Link switches, providing Single IP Management for small business
Works in concert with D-View network management software for larger deployment
Green
Various green features that can minimize the power usage, saving the earth 7

8. Product Overview Product Briefing
Advanced hardware design with excellent performance.
Support 802.3af (PoE) and 802.3at (PoE Plus) for all ports1
High uplink/stacking bandwidth
4 10GE SFP+ ports provide up to 40G bandwidth. It provides high flexibility for physical stacking or uplink application use.
Enlarge MAC address table to 32K (DGS-3600 series is 16K)
Smart Fan
Power saving: Internal heat sensor monitors switch’s temperature and adjusts the fan speed accordingly.
Improve the MTBF with slower fan speed and reduce the noise2
External SD Card
Easy to store and restore file with portable SD card (like FW, configuration file, boot image, syslog or other files).
External Alarm Port3
Provides digital I/O design on external alarm port. It can provide better security protection.
With digital in, DGS-3620 can receive events detected by external sensors (eg. temperature, smoking or anti-theft sensor). The switch can send a trap/log out to report the issue.
With digital out, DGS-3620 can activate external air-conditioner/fan or ring the bell based on the condition customer defined.
Note
DGS PC, DGS P are first D-link L3 Gigabit Managed Switches that support PoE
Usually fan module has lower MTBF value. The lower fan speed can extend the life time of the fan module. Once the fan module’s MTBF is improved, the whole system’s MTBF will be improved, too.
Alarm port configuration will be supported in future firmware release 8

Interchangeable Module Type: Directed Attach Copper (Passive/Active), Optical SR/LRM/LR
10 Gigabit Ethernet Interface Evolution

17. Technology Briefing MPLS
MPLS* provides the “Best-effort Delivery”. It speeds up the data delivery, improves the packet QoS and solves the burden of IP routing
MPLS adopted the core idea of ATM. It locates itself between IP layer and data link layer and takes the responsibility of carrying any traffic over itself
What MPLS learns from ATM:
Thinking of label switching
Using Local Label instead of global IP address 1
47.1 3 40 3 2 1 1 50
47.3 3
47.2 2 IP
Note: DGS-3620 will support MPLS in the future

VPWS (Virtual Private Wire Services) is point-to-point.
VPLS (Virtual private LAN service) is multipoint.
Carrier Ethernet logically connects to MPLS core via Q-tag, Q-in-Q or simple p2p MPLS tunnels
MPLS core carries pure Ethernet over MPLS without customer Layer 3 routing control
Customer routing information is NOT exposed to Service Provider

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