Access Network Processors with Integrated Traffic Management

Mellanox’s NPA is a highly-flexible network processor with integrated traffic management targeting Ethernet network access platforms (ONT/OLT GPON/EPON), copper access platforms (DSLAM) and demarcation devices and 3G/4G WiMAX base stations aggregation and backhaul. The NPA provides high integration, programmable packet processing and advanced flow-based bandwidth control at 10-Gigabit aggregate throughput.
