Although you can equip an SP node with a variety of network adapters and use

the node to make your network connections, the SP Switch Router with the

Switch Router adapter and optional network media cards offers many

advantages when connecting the SP to external networks.

Each media card contains its own IP routing engine with separate memory

containing a full route table of up to 150,000 routes. Direct access provides

much faster lookup times compared to software driven lookups.

Media cards route IP packets independently at rates of 60,000 to 130,000 IP

packets per second. With independent routing available from each media

card, the SP Switch Router gives your SP system excellent scalability

characteristics.

The SP Switch Router has dynamic network configuration to bypass failed

network paths using standard IP protocols.
