-FX family of crossbar switch fabrics are scalable building blocks for the development
of high-performance chassis systems. The Prestera-FX9110 crossbar switch provides 9-ports and supports
108 full-duplex Gigabit Ethernet (GbE) ports; the Prestera-FX9210 crossbar switch is a 12-port fabric that
supports 144 full-duplex GbE ports at full-wire-speed. The Prestera-FX9110 and Prestera-FX9210 devices
take advantage of a cell-based architecture with variable cell sizes and output queue scheduling to support
full speed Prestera-EX and Prestera-MX devices while maintaining Quality of Service (QoS) throughout the
system. Used in conjunction with the Prestera packet processors, Prestera-FX fabric adapters, and the
Alaska
簍
PHY transceivers, Prestera-FX crossbar switch fabrics offer advanced enterprise core features
such as redundancy, hot-swap capability and stability.
