ENET4200Z Switch-Router Flow Processor

Overview

ENET42000Z is a 16Gbps configurable flow processor, implemented on a Xilinx Zynq FPGA, integrating packet processing, protocol interworking, hierarchical traffic management, CFM/OAM, and a Layer 2/3/4 switch aimed at the Metro Access Market.
The ENET4200Z is a Metro Ethernet Forum-compliant multiservice flow processor and traffic manager that is uniquely positioned to deliver an optimal solution for Carrier Ethernet providers.

Features
