• Design commonalities across products with a single device for low-end and high-end systems
• Optimized investments with common switch fabric skills and design re-use across product line
• Optimized cost solution for advanced services applicationsDescriptionAs a switch for 10-20 Gbps platforms, the PRS16G/C192 is an ideal solution for cost-competitive, advanced services applications, such as medium-range routers for network access/edge aggregation with high-demanding packet processing; remote location thin appliances for firewall, SSL, VPN, security, intrusion detection; data center server appliances with deep packet processing; NAS/SAN equipment;and, more generally, service applications requiring a 10-Gbps uplink capability. All of these services are running in the network processors attached to the PRS16G/C192 switch ports.
As a fabric interface for linecards, the PRS16G/C192, enables switch/ adapter cards designed for 10-20 Gbps entry platforms to be used as line cards in chassis-based platforms addressing the higher capacity needs of applications in the Metro/WAN, wireless infrastructure, and enterprise (data center, NAS/SAN, high-end LAN).
