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 support for 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. 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. 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 rackmount design and ease of installation, the DSS-24+ switch provides a cost-effective way of increasing total bandwidth where network traffic is continuously increasing.
