ABOUT THE TIGERSTACK 1000

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 for Layer 2 and Layer 3, these switches can significantly improve the throughput between IP segments or VLANs.

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. 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.
