Switch Architecture

The switches employ a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. This switch also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection.

The switches use 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.

These switches include a slot on the rear panel for hot-swappable 10 Gigabit Ethernet modules. (The 10 Gigabit Ethernet modules are not currently available, but will be supported in the future.)
