1-4 Introduction
Features of the Fast SwitcHub-2s
•
Conforms to the IEEE 802.3 and IEEE 802.3u specifications, as well as
10BASE-T and 100BASE-TX standards
•
Provides two independent RJ-45 10BASE-T / 100BASE-TX Ethernet station
ports, where each logical port consists of 1 MDI port (for connection to hubs
or switches) and 1 MDI-X port (for connection to workstations or servers),
eliminating the need for crossover cables
•
Both ports support full-duplex and half-duplex operation
•
Total bandwidth of up to 200 Mbps (when full-duplex mode is used)
•
Auto-senses transmission speed (10/100 Mbps)
•
Uses adaptive cut-through switching (which dynamically changes among
standard cut-through, fragment free cut-through, and store-and-forward
depending on the error rate)
•
Uses back pressure to eliminate frame loss by "blocking" traffic from end
stations or segments connected directly to the switch when its buffers fill
•
Minimum latency of packet transmission (leading edge to leading edge) less
than 20 microseconds when using cut-through switching
• Uses "on the fly" cut-through technique to transport packets
•
Transparent bridging function supported
•
Address learning function to build the routing information database
•
Operates at maximum packet filtering and forwarding rate
