NPS breaks the barriers of traditional NPUs and CPUs by using C-programmable core to process layers 2 to 7 at extremely high-speed for a combination of unmatched performance and flexibility.
Processors in networking equipment perform two main tasks, data and control plane. Data plane processors must deal with every individual packet and maintain vast performance. Control plane processors deal with applications and management rather than packets and execute millions of lines of code. The difference in functionality imposes different architecture.
Data plane architecture require hundreds of optimized processors to deal with simultaneously with millions of packets and flows, plus Traffic Manager to deal with quality of services. Control plane processors don’t require Traffic Manager and require fewer and larger code with large memory cache to execute millions of lines of code.
Today CPUs even with improved risk cores are targeting also the data plane, however, their architecture is control plane oriented and they provide insufficient performance for the data plane.In low-speed, the CPU can execute control and data plane processing, while high-speed require different processor type for the control and data plane. Today high-speed designs can consist of three field of processors, with NPU at layer 2, 3, a CPU with multiple core at layer 4 to 7 and a control CPU for management. NPS eliminates one field collapsing three field design into two fields with the huge performance advantage and the significant reduction in both assumption and costs. The ideal solution is with the NPS in the data plane focus on speed and the CPU in the control plane running millions of lines of code, the combination of the two will provide the best core performance results. The NPS is unique in many aspects with technology being the first and foremost. In our 10-year old NP family that made EZchip the leading NPU supplier, we have developed special task optimized processor for layers 2, 3, called TOPs.
