Ethernet Port Switch
D-Link's DSS-24+ is a high performance unmanaged Layer 2
Switch that provides users with 24 10/100Mbps Fast Ethernet
ports with NWay auto-negotiation per port. Designed with a
new chipset, the DSS-24+ can automatically detect either
MDI/MDIX cable type through any of the Ethernet ports, which
eliminates the need for an uplink port. The DSS-24+ includes an
optional 2-port 100BASE-FX module with an "SC connector"
increasing cable connectivity to other servers and switches. The
DSS-24+ is targeted for both small office and small business
environments.
The DSS-24+ 24 10/100 Mbps ports adheres to IEEE 802.3,
802.3u, and 802.3x standards, which specify 10Base-T,
100Base-TX and 100BASE-FX Ethernet technologies. With the
DSS-24+ switching function, Store and Forward is implemented
with Rate Adaptation Protocol. (RAP) is an end-to-end rate-
based congestion control mechanism, which ensures data
integrity when packets are transmitted. The switching capability
of the DSS-24+ allots 256Kbytes of allocated memory buffer
per 8-ports. As a result, a complete frame checking and error-
filtering scheme helps prevent any packets with errors from
being transmitted among any broadcast segments. The DSS-24+
also supports Backpressure and pause frame-based flow control
at half duplex mode schemes to ensure zero packet loss by
sending out collision signals when the port's receiving buffer is
full under heavy traffic congestion.
The DSS-24+ switching function forwards data packets at wire
speeds for both 10Mbps and 100Mbps. In addition, the DSS-
24+ data filtering design eliminates all errors of packets at each
port at wire speeds of 10Mbps and 100Mbps. As a switching
solution, the DSS-24+ initiates a MAC address-learning table
aging features. MAC addresses are automatically updated
reducing any broadcast among network segments, which
provides dynamic filtering through auto-learned MAC
addresses and static filtering.
With its rack mount design and ease of installation, the DSS-
24+ switch provides a cost effective way of increasing total
bandwidth where network traffic is continuously increasing.
