The hardware consists of new Connection Managers, packet forwarding cards based on Broadcom 1250 chips that each contain dual processors. Initially, the SMS 10000 cards will use just one of the processors, but over time, as providers need more processing power to handle increased customer demand, the second processors can be turned on.The SMS 10000 used 350 MHz Power PC processors. One MIPS processor on the Broadcom chip is 600 MHz, an with both turned on the chip supports 1 GHz.The new\u00a0 hardware also includes two prt gigabit Ethernet and ATM OC-12 I\/O cards. All the new cards fit in existing SMS 10000 chassis.The added horsepower is designed for streaming applications such as audio and video and is based on demand from carrier customers, Redback says. The average bandwidth used by North American customers has grown from 30K bit\/sec to 60K bit\/sec over the past year, Redback says, and that jump is even greater in Europe.Software enhancements include protection switching that enables traffic streams to fail over to different SONET uplinks in the same SMS 10000 SL box if one SONET uplink fails. The switchover takes less than 50 milliseconds. The software also supports quality of service so providers can engineer ATM virtual circuits to guarantee that priority traffic gets the service characteristics it needs.Redback has upgraded the software to enable the device to collect Layer 2 Tunneling Protocol traffic from customers and distribute them over multiple L2TP tunnels to service provider networks. This load balancing boosts performance by ensuring no single tunnel gets overloaded.The SMS 10000 SL is available in December. Price is not set yet.
