Switch Architecture
The SMC8748L2 switch employs a wire-speed, non-blocking switching
fabric. This permits simultaneous wire-speed transport of multiple packets at
low latency on all ports. The switch also features full-duplex capability on all
ports, which effectively doubles the bandwidth of each connection.
The switch uses store-and-forward switching to ensure maximum data
integrity. With store-and-forward switching, the entire packet must be
received into a buffer and checked for validity before being forwarded. This
prevents errors from being propagated throughout the network.
The switch also includes two slots on the rear panel for slide-in single-port
10GBASE modules that support XFP transceivers.
