    Introduction Switch Architecture The 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.
