These switches can be used to augment or completely replace slow legacy

routers, off-loading local IP traffic to release valuable resources for non-IP

routing or WAN access. With wire-speed performance, these switches can

significantly improve the throughput between IP segments or VLANs.

Switch Architecture

These Gigabit Ethernet switches employ a wire-speed, non-blocking

switching fabric. This permits simultaneous wire-speed transport of

multiple packets at low latency on all ports. The switches also feature

full-duplex capability on all ports, which effectively doubles the bandwidth

of each connection.

For communications between different VLANs, these switches use IP

routing. For communications within the same VLAN, they 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.
