80-Gb/s Integrated Full-Duplex MAC, Packet Processing, Traffic Management and Fabric Access

Currently Viewing:

Integrates Media Access Controller (MAC), packet processing, traffic management and fabric access, all at 80-Gb/s full-duplex wirespeed.
P330 enables complete line-card functionality on a chip for data center applications. By integrating packet processing into the P220/230 line of devices, the solution enables designing high-density switching line cards, ranging from 24 to 48 10-GE ports for data center applications. This translates into a non-compromising switching system design, including a strictly non-blocking fabric, 100 ms packet buffer and densities of up to 768 ports of 10-GE or 40-GE/100-GE equivalent, all within a single-stage fabric. The P330 enables the building of switching systems that optimize power and cost metrics to be similar to Not Recommended for New Design 1-GE switching systems.
