nP3454 Advanced Product Brief PB3454 PB3454 / V0.3 / 04/24/2003 4.4Gbps Integrated Network Processor and Traffic Manager SRAM SRAM SRAM SRAM/ TCAM Applications · Switched Ethernet Platforms · Ethernet Over SONET/SDH · CPE Equipments, MTU/MDU Features 2 GE nP3454 2 GE Host CPU Overview The nP3454 is a successor to the highly adopted AMCC nP3404 Integrated Network Processors and Traffic Management device. The nP3454 is pin compatible with nP3404 and comes with twice the performance of nP3404. nP3454 is implemented using industry leading nPcore TM technology with enhanced Network processing and Traffic Management. The increased performance, efficiency, headroom, flexibility and integration afforded by this proven technology enables customers to deliver more features at lower cost, power and size than ever before. Rich Ethernet interfaces combined with superior programmability provide the best combination for enabling value added Ethernet Services for Access and Metro Ethernet Networks. Industry Leading Performance and Flexibility The nP3454 network processing unit consists of two low power network processing nPcores TM that are based on proven OC-192 OC-192 class products. These nPcores TM along with specialized Network Service Accelerators such as Policy Engine and Special Purpose policing Unit offer unparalleled performance at line rate. The superior programmability and flexibility of these cores enable flexible support for existing and future networking protocols. All the line interfaces on this device are standards compliant maximizing interoperability and flexibility. Value Added Services The traffic management unit of the nP3454 is based on the proven PerStream QueuingTM and Scheduling architecture allowing guaranteed and measurable services. The nP3454 TM's four classes of service enables layered services. The enhanced multicast scheme and programmable memory management provide increased flexibility in traffic management. Software Compatibility The nP3454 is software compatible with prior generation NPUs with its `run to completion' single image programming model and nPKernel software infrastructure. This provides enormous leverage for the customers in reusing software from prior generations of design and achieving quick time to market.
